This makes it possible to use different shader languages by compiling them to that bytecode format. The primary shader language used here is [GLSL](shaders/glsl), most samples also come with [slang](shaders/slang/) and [HLSL](shaders/hlsl) shader sources, making it easy to compare the differences between those shading languages. The [Rust GPU](https://rust-gpu.github.io/) project maintains [Rust](https://www.rust-lang.org/) shader sources in a [separate repo](https://github.com/Rust-GPU/VulkanShaderExamples/tree/master/shaders/rust). - -## A note on synchronization - -Synchronization in the master branch currently isn't optimal und uses ```vkDeviceQueueWaitIdle``` at the end of each frame. This is a heavy operation and is suboptimal in regards to having CPU and GPU operations run in parallel. I'm currently reworking this in the [this branch](https://github.com/SaschaWillems/Vulkan/tree/sync_rework_second_attempt). While still work-in-progress, if you're interested in a more proper way of synchronization in Vulkan, please take a look at the [PR for that branch](https://github.com/SaschaWillems/Vulkan/pull/1224) to see progress. - -## Examples - -### Basics - -- [Basic triangle using Vulkan 1.0](examples/triangle/) - - Basic and verbose example for getting a colored triangle rendered to the screen using Vulkan. This is meant as a starting point for learning Vulkan from the ground up. A huge part of the code is boilerplate that is abstracted away in later examples. - -- [Basic triangle using Vulkan 1.3](examples/trianglevulkan13//) - - Vulkan 1.3 version of the basic and verbose example for getting a colored triangle rendered to the screen. This makes use of features like dynamic rendering simplifying api usage. - -- [Pipelines](examples/pipelines/) - - Using pipeline state objects (pso) that bake state information (rasterization states, culling modes, etc.) along with the shaders into a single object, making it easy for an implementation to optimize usage (compared to OpenGL's dynamic state machine).

-} uboInstance; -``` - -### Preparing the uniform buffer (and memory) - -***Note:*** When preparing the (host) memory to back up the dynamic uniform buffer object it's crucial to take the [minUniformBufferOffsetAlignment](http://vulkan.gpuinfo.org/listreports.php?limit=minUniformBufferOffsetAlignment) limit of the implementation into account. - -Due to the implementation dependent alignment (different from our actual data size) we can't just use a vector and work with pointers instead: - -```cpp -struct UboDataDynamic { - glm::mat4 *model = nullptr; -} uboDataDynamic; -``` -First step is to calculate the alignment required for the data we want to store compared to the min. uniform buffer offset alignment reported by the GPU: - -```cpp -void prepareUniformBuffers() -{ - // Calculate required alignment based on minimum device offset alignment - size_t minUboAlignment = vulkanDevice->properties.limits.minUniformBufferOffsetAlignment; - dynamicAlignment = sizeof(glm::mat4); - if (minUboAlignment > 0) { - dynamicAlignment = (dynamicAlignment + minUboAlignment - 1) & ~(minUboAlignment - 1); - } -``` - -The max. allowed alignment (as per spec) is 256 bytes which may be much higher than the data size we actually need for each entry (one 4x4 matrix = 64 bytes). - -Now that we know the actual alignment required we can create our host memory for the dynamic uniform buffer: - -```cpp - size_t bufferSize = OBJECT_INSTANCES * dynamicAlignment; - uboDataDynamic.model = (glm::mat4*)alignedAlloc(bufferSize, dynamicAlignment); -``` -*(The ```alignedAlloc``` function is a small wrapper doing aligned memory allocation depending on the OS/Compiler)* - -Creating the buffer is the same as creating any other uniform buffer object: - -```cpp -vulkanDevice->createBuffer( - VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT, VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT, &uniformBuffers.dynamic, bufferSize);

The sample is based on the [glTF scene](../gltfscene) sample, and adds data structures, functions and shaders required to render a more complex scene using Crytek's Sponza model. - -## Description - -This example demonstrates how to render a more complex scene loaded from a glTF model. - -It builds on the basic glTF scene sample but instead of using global pipelines, it adds per-material pipelines that are dynamically created from the material definitions of the glTF model. - -Those pipelines pass per-material parameters to the shader so different materials for e.g. displaying opaque and transparent objects can be built from a single shader. - -It also adds data structures, loading functions and shaders to do normal mapping and an easy way of toggling visibility for the scene nodes. - -Note that this is not a full glTF implementation as this would be beyond the scope of a simple example. For a complete glTF Vulkan implementation see [my Vulkan glTF PBR renderer](https://github.com/SaschaWillems/Vulkan-glTF-PBR/). - -For details on glTF refer to the [official glTF 2.0 specification](https://github.com/KhronosGroup/glTF/tree/master/specification/2.0). - -## Points of interest - -**Note:** Points of interest are marked with a **POI** in the code comments: - -```cpp -// POI: This sample uses normal mapping, so we also need to load the tangents from the glTF file -``` - -For this sample, those points of interest mark additions and changes compared to the basic glTF sample. - -### Loading external images - -Unlike the other samples, the glTF scene used for this example doesn't embed the images but uses external ktx images instead. This makes loading a lot faster as the ktx image format natively maps to the GPU and no longer requires us to convert RGB to RGBA, but ktx also allows us to store the mip-chain in the image file itself. - -So instead of creating the textures from a buffer that has been converted from the embedded RGB images, we just load the ktx files from disk: - -```cpp -void VulkanglTFScene::loadImages(tinygltf::Model& input) -{ - images.resize(input.images.size()); - for (size_t i = 0; i < input.images.size(); i++) { - tinygltf::Image& glTFImage = input.images[i]; - images[i].texture.loadFromFile(path + "/" + glTFImage.uri, VK_FORMAT_R8G8B8A8_UNORM, vulkanDevice, copyQueue); - } -} -``` - -### Materials - -#### New Material properties - -```cpp -struct Material -{ - glm::vec4 baseColorFactor = glm::vec4(1.0f); - uint32_t baseColorTextureIndex; - uint32_t normalTextureIndex; - std::string alphaMode = "OPAQUE"; - float alphaCutOff; - bool doubleSided = false; - VkDescriptorSet descriptorSet; - VkPipeline pipeline; -}; -``` - -Several new properties have been added to the material class for this example that are taken from the glTF source. - -Along with the base color we now also get the index of the normal map for that material in ```normalTextureIndex```, and store several material properties required to render the different materials in this scene: - -- ```alphaMode```
-The alpha mode defines how the alpha value for this material is determined. For opaque materials it's ignored, for masked materials the shader will discard fragments based on the alpha cutoff. -- ```alphaCutOff```
-For masked materials, this value specifies the threshold between fully opaque and fully transparent. This is used to discard fragments in the fragment shader. -- ```doubleSided```
-This property is used to select the appropriate culling mode for this material. For double-sided materials, culling will be disabled. - -Retrieving these additional values is done here: - -```cpp -void VulkanglTFScene::loadMaterials(tinygltf::Model& input) -{ - materials.resize(input.materials.size()); - for (size_t i = 0; i < input.materials.size(); i++) { - tinygltf::Material glTFMaterial = input.materials[i]; - ... - materials[i].alphaMode = glTFMaterial.alphaMode; - materials[i].alphaCutOff = (float)glTFMaterial.alphaCutoff; - materials[i].doubleSided = glTFMaterial.doubleSided; - } -} -``` -**Note:** We only read the glTF material properties we use in this sample. There are many more, details on those can be found [here](https://github.com/KhronosGroup/glTF/tree/master/specification/2.0#materials). - -#### Per-Material pipelines - -Unlike most of the other samples that use a few pre-defined pipelines, this sample will dynamically generate per-material pipelines based on material properties in the ```VulkanExample::preparePipelines()``` function - -We first setup pipeline state that's common for all materials: - -```cpp -// Setup common pipeline state properties... -VkPipelineInputAssemblyStateCreateInfo inputAssemblyStateCI = ... -VkPipelineRasterizationStateCreateInfo rasterizationStateCI = ... -VkPipelineColorBlendAttachmentState blendAttachmentStateCI = ... -... - -for (auto &material : glTFScene.materials) -{ - ... -``` - -For each material we then set constant properties for the fragment shader using specialization constants: - -```cpp - struct MaterialSpecializationData { - VkBool32 alphaMask; - float alphaMaskCutoff; - } materialSpecializationData; - - materialSpecializationData.alphaMask = material.alphaMode == "MASK"; - materialSpecializationData.alphaMaskCutoff = material.alphaCutOff; - - std::vector specializationMapEntries = { - vks::initializers::specializationMapEntry(0, offsetof(MaterialSpecializationData, alphaMask), sizeof(MaterialSpecializationData::alphaMask)), - vks::initializers::specializationMapEntry(1, offsetof(MaterialSpecializationData, alphaMaskCutoff), sizeof(MaterialSpecializationData::alphaMaskCutoff)), - }; - VkSpecializationInfo specializationInfo = vks::initializers::specializationInfo(specializationMapEntries, sizeof(materialSpecializationData), &materialSpecializationData); - shaderStages[1].pSpecializationInfo = &specializationInfo; - ... -``` - -We also set the culling mode depending on whether this material is double-sided: - -```cpp - // For double sided materials, culling will be disabled - rasterizationStateCI.cullMode = material.doubleSided ? VK_CULL_MODE_NONE : VK_CULL_MODE_BACK_BIT; -``` - -With those setup we create a pipeline for the current material and store it as a property of the material class: - -```cpp - VK_CHECK_RESULT(vkCreateGraphicsPipelines(device, pipelineCache, 1, &pipelineCI, nullptr, &material.pipeline)); -} -``` - -The material now also get's it's own ```pipeline```. - -The alpha mask properties are used in the fragment shader to distinguish between opaque and transparent materials (```scene.frag```). - -Specialization constant declaration in the shaders's header: - -```glsl -layout (constant_id = 0) const bool ALPHA_MASK = false; -layout (constant_id = 1) const float ALPHA_MASK_CUTOFF = 0.0; -``` -*Note:* The default values provided in the shader are overwritten by the values passed at pipeline creation time. - -For alpha masked materials, fragments below the cutoff threshold are discarded: - -```glsl - vec4 color = texture(samplerColorMap, inUV) * vec4(inColor, 1.0); - - if (ALPHA_MASK) { - if (color.a < ALPHA_MASK_CUTOFF) { - discard; - } - } -``` - -### Normal mapping - -This sample also adds tangent space normal mapping to the rendering equation to add additional detail to the scene, which requires loading additional data. - -#### Normal maps - -Along with the color maps, we now also load all normal maps. From the glTF POV those are just images like all other texture maps, and are stored in the image vector. So as for loading normal maps no code changes are required. The normal map images are then referenced by the index of the normal map of the material, which is now read in addition to the other material properties: - -```cpp -void VulkanglTFScene::loadMaterials(tinygltf::Model& input) -{ - materials.resize(input.materials.size()); - for (size_t i = 0; i < input.materials.size(); i++) { - tinygltf::Material glTFMaterial = input.materials[i]; - ... - // Get the normal map texture index - if (glTFMaterial.additionalValues.find("normalTexture") != glTFMaterial.additionalValues.end()) { - materials[i].normalTextureIndex = glTFMaterial.additionalValues["normalTexture"].TextureIndex(); - } - ... - } -} -``` -**Note:* Unlike the color map index, the normal map index is stored in the ```additionalValues``` of the material. - -The normal maps are then bound to binding 1 via the material's descriptor set in ```VulkanExample::setupDescriptors```: - -```cpp -for (auto& material : glTFScene.materials) { - ... - VkDescriptorImageInfo colorMap = glTFScene.getTextureDescriptor(material.baseColorTextureIndex); - VkDescriptorImageInfo normalMap = glTFScene.getTextureDescriptor(material.normalTextureIndex); - std::vector writeDescriptorSets = { - vks::initializers::writeDescriptorSet(material.descriptorSet, VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER, 0, &colorMap), - vks::initializers::writeDescriptorSet(material.descriptorSet, VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER, 1, &normalMap), - }; - vkUpdateDescriptorSets(device, static_cast(writeDescriptorSets.size()), writeDescriptorSets.data(), 0, nullptr); -} -``` - -The descriptor set itself is then bound to set 1 at draw time in ```VulkanglTFScene::drawNode```: - -```cpp -if (node.mesh.primitives.size() > 0) { - ... - for (VulkanglTFScene::Primitive& primitive : node.mesh.primitives) { - if (primitive.indexCount > 0) { - VulkanglTFScene::Material& material = materials[primitive.materialIndex]; - ... - vkCmdBindDescriptorSets(commandBuffer, VK_PIPELINE_BIND_POINT_GRAPHICS, pipelineLayout, 1, 1, &material.descriptorSet, 0, nullptr); - ... - } - } -} -``` - -Fragment shader interface in ```scene.frag```: - -```glsl -layout (set = 1, binding = 0) uniform sampler2D samplerColorMap; -layout (set = 1, binding = 1) uniform sampler2D samplerNormalMap; -``` - -#### Per-Vertex tangents - -Along with the normals we also need per-vertex tangents and bitangents for normal mapping. As the bitangent can easily be calculated using the normal and tangent, glTF only stores those two. - -So just like with other vertex data already loaded we need to check if there are tangents for a node and load them from the appropriate buffer using a glTF accessor: - -```cpp -void VulkanglTFScene::loadNode(const tinygltf::Node& inputNode, const tinygltf::Model& input, VulkanglTFScene::Node* parent, std::vector& indexBuffer, std::vector& vertexBuffer) -{ - VulkanglTFScene::Node node{}; - ... - - if (inputNode.mesh > -1) { - const tinygltf::Mesh mesh = input.meshes[inputNode.mesh]; - for (size_t i = 0; i < mesh.primitives.size(); i++) { - const tinygltf::Primitive& glTFPrimitive = mesh.primitives[i]; - // Vertices - { - ... - const float* tangentsBuffer = nullptr; - - if (glTFPrimitive.attributes.find("TANGENT") != glTFPrimitive.attributes.end()) { - const tinygltf::Accessor& accessor = input.accessors[glTFPrimitive.attributes.find("TANGENT")->second]; - const tinygltf::BufferView& view = input.bufferViews[accessor.bufferView]; - tangentsBuffer = reinterpret_cast(&(input.buffers[view.buffer].data[accessor.byteOffset + view.byteOffset])); - } - - for (size_t v = 0; v < vertexCount; v++) { - Vertex vert{}; - ... - vert.tangent = tangentsBuffer ? glm::make_vec4(&tangentsBuffer[v * 4]) : glm::vec4(0.0f); - vertexBuffer.push_back(vert); - } - } - ... -``` - -**Note:** The tangent is a four-component vector, with the w-component storing the handedness of the tangent basis. This will be used later on in the shader. - -#### Shaders - -Normal mapping is applied in the ```scene.frag``` fragment shader and boils down to calculating a new world-space normal from the already provided per-vertex normal and the per-fragment tangent space normals provided via the materials' normal map. - -With the per-vertex normal and tangent values passed to the fragment shader, we simply change the way the per-fragment normal is calculated: - -```glsl -vec3 normal = normalize(inNormal); -vec3 tangent = normalize(inTangent.xyz); -vec3 bitangent = cross(inNormal, inTangent.xyz) * inTangent.w; -mat3 TBN = mat3(tangent, bitangent, normal); -vec3 localNormal = texture(samplerNormalMap, inUV).xyz * 2.0 - 1.0; -normal = normalize(TBN * localNormal); -``` - -As noted earlier, glTF does not store bitangents, but we can easily calculate them using the cross product of the normal and tangent. We also multiply this with the tangent's w-component which stores the handedness of the tangent. This is important, as this may differ between nodes in a glTF file. - -After that we calculate the tangent to world-space transformation matrix that is then applied to the per-fragment normal read from the normal map. - -This is then our new normal that is used for the lighting calculations to follow. - -### Rendering the scene - -Just like in the basic glTF sample, the scene hierarchy is added to the command buffer in ```VulkanglTFModel::draw```. Since glTF has a hierarchical node structure this function recursively calls ```VulkanglTFModel::drawNode``` for rendering a give node with it's children. - -The only real change in this sample is binding the per-material pipeline for a node's mesh: - -```cpp -void VulkanglTFScene::drawNode(VkCommandBuffer commandBuffer, VkPipelineLayout pipelineLayout, VulkanglTFScene::Node node) -{ - if (!node.visible) { - return; - } - if (node.mesh.primitives.size() > 0) { - ... - vkCmdPushConstants(commandBuffer, pipelineLayout, VK_SHADER_STAGE_VERTEX_BIT, 0, sizeof(glm::mat4), &nodeMatrix); - for (VulkanglTFScene::Primitive& primitive : node.mesh.primitives) { - if (primitive.indexCount > 0) { - VulkanglTFScene::Material& material = materials[primitive.materialIndex]; - vkCmdBindPipeline(commandBuffer, VK_PIPELINE_BIND_POINT_GRAPHICS, material.pipeline); - vkCmdBindDescriptorSets(commandBuffer, VK_PIPELINE_BIND_POINT_GRAPHICS, pipelineLayout, 1, 1, &material.descriptorSet, 0, nullptr); - vkCmdDrawIndexed(commandBuffer, primitive.indexCount, 1, primitive.firstIndex, 0, 0); - } - } - } - for (auto& child : node.children) { - drawNode(commandBuffer, pipelineLayout, child); - } -} -``` \ No newline at end of file diff --git a/examples/gltfscenerendering/gltfscenerendering.cpp b/examples/gltfscenerendering/gltfscenerendering.cpp deleted file mode 100644 index 7faef44c..00000000 --- a/examples/gltfscenerendering/gltfscenerendering.cpp +++ /dev/null @@ -1,663 +0,0 @@ -/* -* Vulkan Example - Scene rendering -* -* Copyright (C) 2020-2023 by Sascha Willems - www.saschawillems.de -* -* This code is licensed under the MIT license (MIT) (http://opensource.org/licenses/MIT) -* -* Summary: -* Render a complete scene loaded from an glTF file.

For a complete glTF Vulkan implementation see https://github.com/SaschaWillems/Vulkan-glTF-PBR/. - -## Points of interest - -**Note:** Points of interest are marked with a **POI** in the code comments: - -```cpp -// POI: Get buffer data required for vertex skinning -``` - -### Data structures - -Several new data structures are required for doing animations with vertex skinning. The [official glTF spec](https://github.com/KhronosGroup/glTF/tree/master/specification/2.0#skinned-mesh-attributes) has the details on those. - -#### Node additions - -```cpp -struct Node -{ - Node * parent; - uint32_t index; - std::vector children; - Mesh mesh; - glm::vec3 translation{}; - glm::vec3 scale{1.0f}; - glm::quat rotation{}; - int32_t skin = -1; - glm::mat4 matrix; - glm::mat4 getLocalMatrix(); -}; -``` - -The node now also stores the matrix components (```translation```, ```rotation``` ,```scale```) as they can be independently influenced. - -The ```skin``` member is the index of the skin (see below) that is applied to this node. - -A new function called ```getLocalMatrix``` is introduced that calculates the local matrix from the initial one and the current components. - -#### Vertex additions - -```cpp - struct Vertex - { - ... - glm::vec4 jointIndices; - glm::vec4 jointWeights; - }; -``` - -To calculate the final matrix to be applied to the vertex we now pass the indices of the joints (see below) and the weights of those, which determines how strongly this vertex is influenced by the joint. glTF support at max. four indices and weights per joint, so we pass them as four-component vectors. - -#### Skin - -[glTF spec chapter on skins](https://github.com/KhronosGroup/glTF/tree/master/specification/2.0#skins) - -```cpp -struct Skin -{ - std::string name; - Node * skeletonRoot = nullptr; - std::vector inverseBindMatrices; - std::vector joints; - vks::Buffer ssbo; - VkDescriptorSet descriptorSet; -}; -``` - -This struct stores all information required for applying a skin to a mesh. Most important are the ```inverseBindMatrices``` used to transform the geometry into the space of the accompanying joint node. The ```joints``` vector contains the nodes used as joints in this skin. - -We will pass the actual joint matrices for the current animation frame using a shader storage buffer object, so each skin also get's it's own ```ssboo``` along with a descriptor set to be bound at render time. - -#### Animations - -[glTF spec chapter on animations](https://github.com/KhronosGroup/glTF/tree/master/specification/2.0#animations) - -##### Animation sampler -```cpp -struct AnimationSampler -{ - std::string interpolation; - std::vector inputs; - std::vector outputsVec4; -}; -``` - -The animation sampler contains the key frame data read from a buffer using an accessor and the way the key frame is interpolated. This can be ```LINEAR```, which is just a simple linear interpolation over time, ```STEP```, which remains constant until the next key frame is reached, and ```CUBICSPLINE``` which uses a cubic spline with tangents for calculating the interpolated key frames. This is a bit more complex and separately documented in this [glTF spec chapter](https://github.com/KhronosGroup/glTF/tree/master/specification/2.0#appendix-c-spline-interpolation). - -**Note:** For simplicity, this sample only implements ```LINEAR``` interpolation. - -##### Animation channel - -```cpp -struct AnimationChannel -{ - std::string path; - Node * node; - uint32_t samplerIndex; -}; -``` - -The animation channel connects the node with a key frame specified by an animation sampler with the ```path``` member specifying the node property to animate, which is either ```translation```, ```rotation```, ```scale``` or ```weights```. The latter one refers to morph targets and not vertex weights (for skinning) and is not used in this sample. - -##### Animation -```cpp -struct Animation -{ - std::string name; - std::vector samplers; - std::vector channels; - float start = std::numeric_limits::max(); - float end = std::numeric_limits::min(); - float currentTime = 0.0f; -}; -``` - -The animation itself then contains the animation samplers and channels along with timing information. - -#### Loading and passing the data - -##### Vertex attributes - -This samples adds two new vertex attributes for passing per-vertex `joints` and `weights` information. As with other per-vertex attributes, these need to be loaded using glTF accessors in `VulkanglTFModel::loadNode`: - -```cpp -// Get vertex joint indices -if (glTFPrimitive.attributes.find("JOINTS_0") != glTFPrimitive.attributes.end()) -{ - const tinygltf::Accessor & accessor = input.accessors[glTFPrimitive.attributes.find("JOINTS_0")->second]; - const tinygltf::BufferView &view = input.bufferViews[accessor.bufferView]; - jointIndicesBuffer = reinterpret_cast(&(input.buffers[view.buffer].data[accessor.byteOffset + view.byteOffset])); -} -// Get vertex joint weights -if (glTFPrimitive.attributes.find("WEIGHTS_0") != glTFPrimitive.attributes.end()) -{ - const tinygltf::Accessor & accessor = input.accessors[glTFPrimitive.attributes.find("WEIGHTS_0")->second]; - const tinygltf::BufferView &view = input.bufferViews[accessor.bufferView]; - jointWeightsBuffer = reinterpret_cast(&(input.buffers[view.buffer].data[accessor.byteOffset + view.byteOffset])); -} -``` - -As usual we check if those attributes actually exist inside the glTF file, and if so we use the accessor and buffer view to get a pointer to the required vertex attributes. - -The new attributes are added to the vertex input state of our pipeline in `VulkanExample::preparePipelines` at locations 4 and 5: - -```cpp -const std::vector vertexInputAttributes = { - ... - {4, 0, VK_FORMAT_R32G32B32A32_SFLOAT, offsetof(VulkanglTFModel::Vertex, jointIndices)}, - {5, 0, VK_FORMAT_R32G32B32A32_SFLOAT, offsetof(VulkanglTFModel::Vertex, jointWeights)}, -}; -``` - -Vertex shader interface in `skinnedmodel.vert`: - -```glsl -layout (location = 4) in vec4 inJointIndices; -layout (location = 5) in vec4 inJointWeights; -``` - -##### Skins - -Loading skins is done in `VulkanglTFModel::loadSkin` and aside from getting the required data from the glTF sources into our own structures, this method also creates a buffer for uploading the inverse bind matrices: - -```cpp -void VulkanglTFModel::loadSkins(tinygltf::Model &input) -{ - skins.resize(input.skins.size()); - - for (size_t i = 0; i < input.skins.size(); i++) - { - tinygltf::Skin glTFSkin = input.skins[i]; - ... - if (glTFSkin.inverseBindMatrices > -1) - { - const tinygltf::Accessor & accessor = input.accessors[glTFSkin.inverseBindMatrices]; - const tinygltf::BufferView &bufferView = input.bufferViews[accessor.bufferView]; - const tinygltf::Buffer & buffer = input.buffers[bufferView.buffer]; - skins[i].inverseBindMatrices.resize(accessor.count); - memcpy(skins[i].inverseBindMatrices.data(), &buffer.data[accessor.byteOffset + bufferView.byteOffset], accessor.count * sizeof(glm::mat4)); - - vulkanDevice->createBuffer( - VK_BUFFER_USAGE_STORAGE_BUFFER_BIT, - VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT | VK_MEMORY_PROPERTY_HOST_COHERENT_BIT, - &skins[i].ssbo, - sizeof(glm::mat4) * skins[i].inverseBindMatrices.size(), - skins[i].inverseBindMatrices.data()); - ... - } - } -``` - -Vertex shader interface in `skinnedmodel.vert`: - -```glsl -layout(std430, set = 1, binding = 0) readonly buffer JointMatrices { - mat4 jointMatrices[]; -}; -``` - -As with e.g. vertex attributes we retrieve the inverse bind matrices from the glTF accessor and buffer view. These are used at a later point for generating the actual animation matrices. - -We then create a shader storage buffer object (for each skin) big enough to hold all animation matrices. See [Updating the animations](#UpdatingAnimation) for how these are calculated and updated. - -**Note**: For simplicity we create a host visible SSBO. This makes code easier to read. In a real-world application you'd use a device local SSBO instead. - -##### Animations - -Loading the animation data is done in ```VulkanglTFModel::loadAnimations``` and is also mostly about getting the required data from glTF into our own sources, including sampler and channel data. - -The most interesting part is getting the input and output pairs for the animation's samplers, which are loaded using glTF's accessors. - -We first load the **sampler's input values**, containing keyframe time values. These are also used to determine the start and end time of the animation: - -```cpp -void VulkanglTFModel::loadAnimations(tinygltf::Model &input) - ... - for (size_t i = 0; i < input.animations.size(); i++) - { - ... - for (size_t j = 0; j < glTFAnimation.samplers.size(); j++) - { - ... - { - const tinygltf::Accessor & accessor = input.accessors[glTFSampler.input]; - const tinygltf::BufferView &bufferView = input.bufferViews[accessor.bufferView]; - const tinygltf::Buffer & buffer = input.buffers[bufferView.buffer]; - const void * dataPtr = &buffer.data[accessor.byteOffset + bufferView.byteOffset]; - const float * buf = static_cast(dataPtr); - for (size_t index = 0; index < accessor.count; index++) - { - dstSampler.inputs.push_back(buf[index]); - } - // Adjust animation's start and end times - for (auto input : animations[i].samplers[j].inputs) - { - if (input < animations[i].start) - { - animations[i].start = input; - }; - if (input > animations[i].end) - { - animations[i].end = input; - } - } - } -``` - -Next up are the **sampler's output values** containing the keyframe output values for the input time values read above: - -```cpp -void VulkanglTFModel::loadAnimations(tinygltf::Model &input) - ... - for (size_t i = 0; i < input.animations.size(); i++) - { - ... - for (size_t j = 0; j < glTFAnimation.samplers.size(); j++) - { - ... - // Read sampler keyframe output translate/rotate/scale values - { - const tinygltf::Accessor & accessor = input.accessors[glTFSampler.output]; - const tinygltf::BufferView &bufferView = input.bufferViews[accessor.bufferView]; - const tinygltf::Buffer & buffer = input.buffers[bufferView.buffer]; - const void * dataPtr = &buffer.data[accessor.byteOffset + bufferView.byteOffset]; - switch (accessor.type) - { - case TINYGLTF_TYPE_VEC3: { - const glm::vec3 *buf = static_cast(dataPtr); - for (size_t index = 0; index < accessor.count; index++) - { - dstSampler.outputsVec4.push_back(glm::vec4(buf[index], 0.0f)); - } - break; - } - case TINYGLTF_TYPE_VEC4: { - const glm::vec4 *buf = static_cast(dataPtr); - for (size_t index = 0; index < accessor.count; index++) - { - dstSampler.outputsVec4.push_back(buf[index]); - } - break; - } - default: { - std::cout << "unknown type" << std::endl; - break; - } - } - } -``` - -As the comment notes these outputs apply to a certain animation target path, which is either a translation, rotation or scale. - -The path and node that the output keyframe values are applied to are part of the animation's channel: - -```cpp - ... - for (size_t i = 0; i < input.animations.size(); i++) - { - ... - for (size_t j = 0; j < glTFAnimation.channels.size(); j++) - { - tinygltf::AnimationChannel glTFChannel = glTFAnimation.channels[j]; - AnimationChannel & dstChannel = animations[i].channels[j]; - dstChannel.path = glTFChannel.target_path; - dstChannel.samplerIndex = glTFChannel.sampler; - dstChannel.node = nodeFromIndex(glTFChannel.target_node); - } -``` - -So if the animation's channel's path is set to ```translation```, the keyframe output values contain translation values that are applied to the channel's node depending on the current animation time. - - -#### Updating the animation - -With all required structures loaded, the next step is updating the actual animation data. This is done inside the ```VulkanglTFModel::updateAnimation``` function, where the data from the animation's samplers and channels is applied to the animation targets of the destination node. - -We first update the active animation's current timestamp and also check if we need to restart it: - -```cpp -Animation &animation = animations[activeAnimation]; -animation.currentTime += deltaTime; -if (animation.currentTime > animation.end) -{ - animation.currentTime -= animation.end; -} -``` - -Next we go through all the channels that are applied to this animation (translation, rotation, scale) and try to find the input keyframe values for the current timestamp: - -```cpp -for (auto &channel : animation.channels) -{ - AnimationSampler &sampler = animation.samplers[channel.samplerIndex]; - for (size_t i = 0; i < sampler.inputs.size() - 1; i++) - { - // Get the input keyframe values for the current time stamp - if ((animation.currentTime >= sampler.inputs[i]) && (animation.currentTime <= sampler.inputs[i + 1])) - { - // Calculate interpolation value based on timestamp, Update node, see next paragraph - } - } -} -``` - -Inside the above loop we then calculate the interpolation value based on the animation's current time and the sampler's input keyframes for the current and next frame: - -```cpp -float a = (animation.currentTime - sampler.inputs[i]) / (sampler.inputs[i + 1] - sampler.inputs[i]); -``` - -This interpolation value is then used to apply the keyframe output values to the appropriate channel: - -```cpp -if (channel.path == "translation") -{ - channel.node->translation = glm::mix(sampler.outputsVec4[i], sampler.outputsVec4[i + 1], a); -} -if (channel.path == "rotation") -{ - glm::quat q1; - q1.x = sampler.outputsVec4[i].x; - q1.y = sampler.outputsVec4[i].y; - q1.z = sampler.outputsVec4[i].z; - q1.w = sampler.outputsVec4[i].w; - - glm::quat q2; - q2.x = sampler.outputsVec4[i + 1].x; - q2.y = sampler.outputsVec4[i + 1].y; - q2.z = sampler.outputsVec4[i + 1].z; - q2.w = sampler.outputsVec4[i + 1].w; - - channel.node->rotation = glm::normalize(glm::slerp(q1, q2, a)); -} -if (channel.path == "scale") -{ - channel.node->scale = glm::mix(sampler.outputsVec4[i], sampler.outputsVec4[i + 1], a); -} -``` - -**Note:** As mentioned earlier, this sample only supports linear interpolation types. - -Translation and scale is a simple linear interpolation between the output keyframe values of the current and next frame. - -Rotations use quaternions and as such are interpolated using spherical linear interpolation. - -After the node's animation components have been updated, we update all node joints: - -```cpp -for (auto &node : nodes) -{ - updateJoints(node); -} -``` - -The ```updateJoints``` function will calculate the actual joint matrices and update the shader storage buffer object: - -```cpp -void VulkanglTFModel::updateJoints(VulkanglTFModel::Node *node) -{ - if (node->skin > -1) - { - // Update the joint matrices - glm::mat4 inverseTransform = glm::inverse(getNodeMatrix(node)); - Skin skin = skins[node->skin]; - size_t numJoints = (uint32_t) skin.joints.size(); - std::vector jointMatrices(numJoints); - for (size_t i = 0; i < numJoints; i++) - { - jointMatrices[i] = getNodeMatrix(skin.joints[i]) * skin.inverseBindMatrices[i]; - jointMatrices[i] = inverseTransform * jointMatrices[i]; - } - // Update ssbo - skin.ssbo.copyTo(jointMatrices.data(), jointMatrices.size() * sizeof(glm::mat4)); - } - - for (auto &child : node->children) - { - updateJoints(child); - } -} -``` - -Note the use of the ```getNodeMatrix``` function which will return the current matrix of a given node calculated from the node hierarchy and the node's current translate/rotate/scale values updated earlier. This is the actual matrix that's updated by the current animation state. - -After this we copy the new joint matrices to the shader storage buffer object of the current skin to make it available to the shader. - -#### Rendering the model - -With all the matrices calculated and made available to the shaders, we can now finally render our animated model using vertex skinning. - -Rendering the glTF model is done in ```VulkanglTFModel::draw``` which is called at command buffer creation. Since glTF has a hierarchical node structure this function recursively calls ```VulkanglTFModel::drawNode``` for rendering a give node with it's children: - -```cpp -void VulkanglTFModel::drawNode(VkCommandBuffer commandBuffer, VkPipelineLayout pipelineLayout, VulkanglTFModel::Node node) -{ - if (node.mesh.primitives.size() > 0) - { - // Pass the node's matrix via push constants - // Traverse the node hierarchy to the top-most parent to get the final matrix of the current node - glm::mat4 nodeMatrix = node.matrix; - VulkanglTFModel::Node *currentParent = node.parent; - while (currentParent) - { - nodeMatrix = currentParent->matrix * nodeMatrix; - currentParent = currentParent->parent; - } - // Pass the final matrix to the vertex shader using push constants - vkCmdPushConstants(commandBuffer, pipelineLayout, VK_SHADER_STAGE_VERTEX_BIT, 0, sizeof(glm::mat4), &nodeMatrix); - // Bind SSBO with skin data for this node to set 1 - vkCmdBindDescriptorSets(commandBuffer, VK_PIPELINE_BIND_POINT_GRAPHICS, pipelineLayout, 1, 1, &skins[node.skin].descriptorSet, 0, nullptr); - for (VulkanglTFModel::Primitive &primitive : node.mesh.primitives) - { - if (primitive.indexCount > 0) - { - ... - vkCmdDrawIndexed(commandBuffer, primitive.indexCount, 1, primitive.firstIndex, 0, 0); - } - } - } - for (auto &child : node.children) - { - drawNode(commandBuffer, pipelineLayout, *child); - } -} -``` - -There are two points-of-interest in this code related to vertex skinning. - -First is passing the (fixed) model matrix via a push constant, which is not directly related to the animation itself but required later on on the shader: - -```cpp -glm::mat4 nodeMatrix = node.matrix; -VulkanglTFModel::Node *currentParent = node.parent; -while (currentParent) -{ - nodeMatrix = currentParent->matrix * nodeMatrix; - currentParent = currentParent->parent; -} -// Pass the final matrix to the vertex shader using push constants -vkCmdPushConstants(commandBuffer, pipelineLayout, VK_SHADER_STAGE_VERTEX_BIT, 0, sizeof(glm::mat4), &nodeMatrix); -``` - -As this matrix won't change in our case, we pass this is a push constant to the vertex shader. - -And we also bind the shader storage buffer object of the skin so the vertex shader get's access to the current joint matrices for the skin to be applied to that particular node: - -```cpp -vkCmdBindDescriptorSets(commandBuffer, VK_PIPELINE_BIND_POINT_GRAPHICS, pipelineLayout, 1, 1, &skins[node.skin].descriptorSet, 0, nullptr); -``` - -With the application side setup done, we can now take a look at the vertex shader that does the actual vertex skinning (```skinnedmodel.vert```). - -As mentioned earlier, the interface has been expanded with values and attributes related to vertex skinning: - -```glsl -#version 450 - -... -layout (location = 4) in vec4 inJointIndices; -layout (location = 5) in vec4 inJointWeights; - -... - -layout(push_constant) uniform PushConsts { - mat4 model; -} primitive; - -layout(std430, set = 1, binding = 0) readonly buffer JointMatrices { - mat4 jointMatrices[]; -}; -``` - -Those are then used to calculate the skin matrix that's applied to the vertex position: - -```glsl -void main() -{ - ... - - mat4 skinMat = - inJointWeights.x * jointMatrices[int(inJointIndices.x)] + - inJointWeights.y * jointMatrices[int(inJointIndices.y)] + - inJointWeights.z * jointMatrices[int(inJointIndices.z)] + - inJointWeights.w * jointMatrices[int(inJointIndices.w)]; - - gl_Position = uboScene.projection * uboScene.view * primitive.model * skinMat * vec4(inPos.xyz, 1.0); - - ... -} -``` - -The skin matrix is a linear combination of the joint matrices. The indices of the joint matrices to be applied are taken from the ```inJointIndices``` vertex attribute, with each component (xyzw) storing one index, and those matrices are then weighted by the ```inJointWeights``` vertex attribute to calculate the final skin matrix that is applied to this vertex. \ No newline at end of file diff --git a/examples/gltfskinning/gltfskinning.cpp b/examples/gltfskinning/gltfskinning.cpp deleted file mode 100644 index 6bade0c6..00000000 --- a/examples/gltfskinning/gltfskinning.cpp +++ /dev/null @@ -1,1006 +0,0 @@ -/* -* Vulkan Example - glTF skinned animation -* -* Copyright (C) 2020-2023 by Sascha Willems - www.saschawillems.de -* -* This code is licensed under the MIT license (MIT) (http://opensource.org/licenses/MIT) -*/ - -/* - * Shows how to load and display an animated scene from a glTF file using vertex skinning - * See the accompanying README.md for a short tutorial on the data structures and functions required for vertex skinning - * - * For details on how glTF 2.0 works, see the official spec at https://github.com/KhronosGroup/glTF/tree/master/specification/2.0 - * - * If you are looking for a complete glTF implementation, check out https://github.com/SaschaWillems/Vulkan-glTF-PBR/ - */ - -#include "gltfskinning.h" - -/* - - glTF model class - - Contains everything required to render a skinned glTF model in Vulkan - This class is simplified compared to glTF's feature set but retains the basic glTF structure required for this sample - - */ - -/* - Get a node's local matrix from the current translation, rotation and scale values - These are calculated from the current animation an need to be calculated dynamically - */ -glm::mat4 VulkanglTFModel::Node::getLocalMatrix() -{ - return glm::translate(glm::mat4(1.0f), translation) * glm::mat4(rotation) * glm::scale(glm::mat4(1.0f), scale) * matrix;

If this feature is not available multiple indirect draw commands are used. ***Note:*** When issuing many draw counts also make sure to stay within the limitations of [`maxDrawIndirectCount`](http://vulkan.gpuinfo.org/listreports.php?limit=maxDrawIndirectCount). - -## Description - -This example demonstrates the use of indirect draw commands. In addition to draw functions like [`vkCmdDraw`](https://www.khronos.org/registry/vulkan/specs/1.0/man/html/vkCmdDraw.html) and [`vkCmdDrawIndexed`](https://www.khronos.org/registry/vulkan/specs/1.0/man/html/vkCmdDrawIndexed.html), where the parameters that specify what is drawn are passed directly to the function ("direct drawing"), there also exist indirect drawing commands. - -[`vkCmdDrawIndirect`](https://www.khronos.org/registry/vulkan/specs/1.0/man/html/vkCmdDrawIndirect.html) and [`vkCmdDrawIndexedIndirect`](https://www.khronos.org/registry/vulkan/specs/1.0/man/html/vkCmdDrawIndexedIndirect.html) take the draw commands from a buffer object that contains descriptions on the draw commands to be issued, including instance and index counts, vertex offsets, etc. This also allows to draw multiple geometries with a single draw command as long as they're backed up by the same vertex (and index) buffer. - -This adds several new possibilities of generating (and updating) actual draw commands, as that buffer can be generated and updated offline with no need to actually update the command buffers that contain the actual drawing functions. - -Using indirect drawing you can generate the draw commands offline ahead of time on the CPU and even update them using shaders (as they're stored in a device local buffer). This adds lots of new possibilities to update draw commands without the CPU being involved, including GPU-based culling. - -The example generates a single indirect buffer that contains draw commands for 12 different plants at random position, scale and rotation also using instancing to render the objects multiple times. The whole foliage (and trees) seen in the screen are drawn using only one draw call. - -The different plant meshes are loaded from a single file and stored inside a single index and vertex buffer, index offsets are stored inside the indirect draw commands. - -For details on the use of instancing (and instanced vertex attributes), see the [instancing example](../instancing) - -## Points of interest - -### Preparing the indirect draw -The example generates the indirect drawing buffer right at the start. First step is to generate the data for the indirect draws. Vulkan has a dedicated struct for this called `VkDrawIndexedIndirectCommand` and the example uses a `std::vector` to store these before uploading them to the GPU: -```cpp -void prepareIndirectData() -{ - ... - uint32_t m = 0; - for (auto& meshDescriptor : meshes.plants.meshDescriptors) - { - VkDrawIndexedIndirectCommand indirectCmd{}; - indirectCmd.instanceCount = OBJECT_INSTANCE_COUNT; - indirectCmd.firstInstance = m * OBJECT_INSTANCE_COUNT; - indirectCmd.firstIndex = meshDescriptor.indexBase; - indirectCmd.indexCount = meshDescriptor.indexCount; - indirectCommands.push_back(indirectCmd); - m++; - } - ... -} -``` -The meshDescriptor is generated by the mesh loader and contains the index base and count of that mesh inside the global index buffer containing all plant meshes for the scenery. - -The indirect draw command for the second plant mesh looks like this: -```cpp -indirectCmd.indexCount = 1668; -indirectCmd.instanceCount = 2048; -indirectCmd.firstIndex = 960; -indirectCmd.vertexOffset = 0; -indirectCmd.firstInstance = 2048; -``` -Which will result in 2048 instances of the index data starting at index 960 (using 1668 indices) being drawn, the first instance is also important as the shader is using it for the instanced attributes of that object (position, rotation, scale). - -Once we have filled that vector we need to create the buffer that the GPU uses to read the indirect commands from: - -```cpp -VK_CHECK_RESULT(vulkanDevice->createBuffer( - VK_BUFFER_USAGE_INDIRECT_BUFFER_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT, - VK_MEMORY_PROPERTY_DEVICE_LOCAL_BIT, - &indirectCommandsBuffer, - stagingBuffer.size)); - -vulkanDevice->copyBuffer(&stagingBuffer, &indirectCommandsBuffer, queue); -``` -To use a buffer for indirect draw commands you need to specify the ```VK_BUFFER_USAGE_INDIRECT_BUFFER_BIT``` usage flag at creation time. As the buffer is never again changed on the host side we stage it to the GPU to maximize performance. - -### Rendering -If the [`multiDrawIndirect`](http://vulkan.gpuinfo.org/listreports.php?feature=multiDrawIndirect) is supported, we can issue all indirect draws with one single draw call: -```cpp -void buildCommandBuffers() -{ - ... - for (int32_t i = 0; i < drawCmdBuffers.size(); ++i) - { - vkCmdDrawIndexedIndirect(drawCmdBuffers[i], indirectCommandsBuffer.buffer, 0, indirectDrawCount, sizeof(VkDrawIndexedIndirectCommand)); - } -} -``` -We just pass the buffer handle to the buffer containing the indirect draw commands and the number of drawCounts. - -The non-indirect, non-instanced equivalent of this would be: -```cpp -for (auto indirectCmd : indirectCommands) - { - for (uint32_t j = 0; j < indirectCmd.instanceCount; j++) - { - vkCmdDrawIndexed(drawCmdBuffers[i], indirectCmd.indexCount, 1, indirectCmd.firstIndex, 0, indirectCmd.firstInstance + j); - } - } -``` - -If the GPU does not support ```multiDrawIndirect``` we have to issue the indirect draw commands one-by-one using a buffer offset instead: -```cpp -for (auto j = 0; j < indirectCommands.size(); j++) -{ - vkCmdDrawIndexedIndirect(drawCmdBuffers[i], indirectCommandsBuffer.buffer, j * sizeof(VkDrawIndexedIndirectCommand), 1, sizeof(VkDrawIndexedIndirectCommand)); -} -``` - -### Acknowledgments -- Plant and foliage models by [Hugues Muller](http://www.yughues-folio.com/) diff --git a/examples/indirectdraw/indirectdraw.cpp b/examples/indirectdraw/indirectdraw.cpp deleted file mode 100644 index ced8d3c7..00000000 --- a/examples/indirectdraw/indirectdraw.cpp +++ /dev/null @@ -1,483 +0,0 @@ -/* -* Vulkan Example - Indirect drawing -* -* Copyright (C) 2016-2023 by Sascha Willems - www.saschawillems.de -* -* This code is licensed under the MIT license (MIT) (http://opensource.org/licenses/MIT) -* -* Summary: -* Use a device local buffer that stores draw commands for instanced rendering of different meshes stored -* in the same buffer. -* -* Indirect drawing offloads draw command generation and offers the ability to update them on the GPU -* without the CPU having to touch the buffer again, also reducing the number of drawcalls. -* -* The example shows how to setup and fill such a buffer on the CPU side, stages it to the device and -* shows how to render it using only one draw command. -* -* See readme.md for details -* -*/ - -#include "vulkanexamplebase.h" -#include "VulkanglTFModel.h" - -// Number of instances per object -#if defined(__ANDROID__) -#define OBJECT_INSTANCE_COUNT 1024 -// Circular range of plant distribution -#define PLANT_RADIUS 20.0f -#else -#define OBJECT_INSTANCE_COUNT 2048 -// Circular range of plant distribution -#define PLANT_RADIUS 25.0f -#endif - -class VulkanExample : public VulkanExampleBase -{ -public: - struct { - vks::Texture2DArray plants;

This requires the format used to support the ```BLIT_SRC_BIT``` and the ```BLIT_DST_BIT``` flags. If these are not supported, the image format can't be used to blit and you'd either have to choose a different format or use e.g. a compute shader to generate mip levels. The example uses the ```VK_FORMAT_R8G8B8A8_UNORM``` that should support these flags on most implementations. - -***Note:*** Use [```vkGetPhysicalDeviceFormatProperties```](https://www.khronos.org/registry/vulkan/specs/1.0/man/html/vkGetPhysicalDeviceFormatProperties.html) to check if the format supports the blit flags first. - -## Description - -This examples demonstrates how to generate a complete texture mip-chain at runtime instead of loading offline generated mip-maps from a texture file. - -While usually not applied for textures stored on the disk (that usually have the mips generated offline and stored in the file, see [basic texture mapping example](../texture)) this technique is used textures are generated at runtime, e.g. when doing dynamic cubemaps or other render-to-texture effects. - -Having mip-maps for runtime generated textures offers lots of benefits, both in terms of image stability and performance. Without mip mapping the image will become noisy, especially with high frequency textures (and texture components like specular) and using mip mapping will result in higher performance due to caching. - -Though this example only generates one mip-chain for a single texture at the beginning this technique can also be used during normal frame rendering to generate mip-chains for dynamic textures. - -Some GPUs also offer ```asynchronous transfer queues``` (check for queue families with only the ? ```VK_QUEUE_TRANSFER_BIT``` set) that may be used to speed up such operations. - -## Points of interest - -### Image setup -Even though we'll only upload the first mip level initially, we create the image with number of desired mip levels. The following formula is used to calculate the number of mip levels based on the max. image extent: - -```cpp -texture.mipLevels = floor(log2(std::max(texture.width, texture.height))) + 1; -``` - -This is then passed to the image creat info: - -```cpp -VkImageCreateInfo imageCreateInfo = vkTools::initializers::imageCreateInfo(); -imageCreateInfo.imageType = VK_IMAGE_TYPE_2D; -imageCreateInfo.format = format; -imageCreateInfo.mipLevels = texture.mipLevels; -... -``` - -Setting the number of desired mip levels is necessary as this is used for allocating the right amount of memory for the image (```vkAllocateMemory```). - -### Upload base mip level - -Before generating the mip-chain we need to copy the image data loaded from disk into the newly generated image. This image will be the base for our mip-chain: - -```cpp -VkBufferImageCopy bufferCopyRegion = {}; -bufferCopyRegion.imageSubresource.aspectMask = VK_IMAGE_ASPECT_COLOR_BIT; -bufferCopyRegion.imageSubresource.mipLevel = 0; -bufferCopyRegion.imageExtent.width = texture.width; -bufferCopyRegion.imageExtent.height = texture.height; -bufferCopyRegion.imageExtent.depth = 1; - -vkCmdCopyBufferToImage(copyCmd, stagingBuffer, texture.image, VK_IMAGE_LAYOUT_TRANSFER_DST_OPTIMAL, 1, &bufferCopyRegion); -``` - -### Prepare base mip level -As we are going to blit ***from*** the base mip-level just uploaded we also need to set insert an image memory barrier that sets the image layout to ```TRANSFER_SRC``` for the base mip level: - -```cpp -VkImageSubresourceRange subresourceRange = {}; -subresourceRange.aspectMask = VK_IMAGE_ASPECT_COLOR_BIT; -subresourceRange.levelCount = 1; -subresourceRange.layerCount = 1; - -vks::tools::insertImageMemoryBarrier( - copyCmd, - texture.image, - VK_ACCESS_TRANSFER_WRITE_BIT, - VK_ACCESS_TRANSFER_READ_BIT, - VK_IMAGE_LAYOUT_TRANSFER_DST_OPTIMAL, - VK_IMAGE_LAYOUT_TRANSFER_SRC_OPTIMAL, - VK_PIPELINE_STAGE_TRANSFER_BIT, - VK_PIPELINE_STAGE_TRANSFER_BIT, - subresourceRange); -``` - -### Generating the mip-chain -There are two different ways of generating the mip-chain. The first one is to blit down the whole mip-chain from level n-1 to n, the other way would be to always use the base image and blit down from that to all levels. This example uses the first one. - -***Note:*** Blitting (same for copying) images is done inside of a command buffer that has to be submitted and as such has to be synchronized before using the new image with e.g. a ```vkFence```. - -We simply loop over all remaining mip levels (level 0 was loaded from disk) and prepare a ```VkImageBlit``` structure for each blit from mip level i-1 to level i. - -First the source for out blit. This is the previous mip level. The dimensions of the blit source are specified by srcOffset: -```cpp -for (int32_t i = 1; i < texture.mipLevels; i++) -{ - VkImageBlit imageBlit{}; - - // Source - imageBlit.srcSubresource.aspectMask = VK_IMAGE_ASPECT_COLOR_BIT; - imageBlit.srcSubresource.layerCount = 1; - imageBlit.srcSubresource.mipLevel = i-1; - imageBlit.srcOffsets[1].x = int32_t(texture.width >> (i - 1)); - imageBlit.srcOffsets[1].y = int32_t(texture.height >> (i - 1)); - imageBlit.srcOffsets[1].z = 1; -``` -Setup for the destination mip level (1), with the dimensions for the blit destination specified in dstOffsets[1]: -```cpp - // Destination - imageBlit.dstSubresource.aspectMask = VK_IMAGE_ASPECT_COLOR_BIT; - imageBlit.dstSubresource.layerCount = 1; - imageBlit.dstSubresource.mipLevel = i; - imageBlit.dstOffsets[1].x = int32_t(texture.width >> i); - imageBlit.dstOffsets[1].y = int32_t(texture.height >> i); - imageBlit.dstOffsets[1].z = 1; -``` - -Before we can blit to this mip level, we need to transition its image layout to ```TRANSFER_DST```: -```cpp - VkImageSubresourceRange mipSubRange = {}; - mipSubRange.aspectMask = VK_IMAGE_ASPECT_COLOR_BIT; - mipSubRange.baseMipLevel = i; - mipSubRange.levelCount = 1; - mipSubRange.layerCount = 1; - - // Prepare current mip level as image blit destination - vks::tools::insertImageMemoryBarrier( - blitCmd, - texture.image, - 0, - VK_ACCESS_TRANSFER_WRITE_BIT, - VK_IMAGE_LAYOUT_UNDEFINED, - VK_IMAGE_LAYOUT_TRANSFER_DST_OPTIMAL, - VK_PIPELINE_STAGE_TRANSFER_BIT, - VK_PIPELINE_STAGE_TRANSFER_BIT, - mipSubRange); -``` -Note that we set the ```baseMipLevel``` member of the subresource range so the image memory barrier will only affect the one mip level we want to copy to. - -Now that the mip level we want to copy from and the one we'll copy to have are in the proper layout (transfer source and destination) we can issue the [```vkCmdBlitImage```](https://www.khronos.org/registry/vulkan/specs/1.0/man/html/vkCmdBlitImage.html) to copy from mip level (i-1) to mip level (i): - -```cpp - vkCmdBlitImage( - blitCmd, - texture.image, - VK_IMAGE_LAYOUT_TRANSFER_SRC_OPTIMAL, - texture.image, - VK_IMAGE_LAYOUT_TRANSFER_DST_OPTIMAL, - 1, - &imageBlit, - VK_FILTER_LINEAR); -``` -```vkCmdBlitImage``` does the (down) scaling from mip level (i-1) to mip level (i) using a linear filter. - -After the blit is done we can use this mip level as a base for the next level, so we transition the layout from ```TRANSFER_DST_OPTIMAL``` to ```TRANSFER_SRC_OPTIMAL``` so we can use this level as transfer source for the next level: - -```cpp - // Prepare current mip level as image blit source for next level - vks::tools::insertImageMemoryBarrier( - copyCmd, - texture.image, - VK_ACCESS_TRANSFER_WRITE_BIT, - VK_ACCESS_TRANSFER_READ_BIT, - VK_IMAGE_LAYOUT_TRANSFER_DST_OPTIMAL, - VK_IMAGE_LAYOUT_TRANSFER_SRC_OPTIMAL, - VK_PIPELINE_STAGE_TRANSFER_BIT, - VK_PIPELINE_STAGE_TRANSFER_BIT, - mipSubRange); -} -``` - -### Final image layout transitions -Once the loop is done we need to transition all mip levels of the image to their actual usage layout, which is ```SHADER_READ``` for this example. Note that after the loop all levels will be in the ```TRANSER_SRC``` layout allowing us to transfer the whole image at once: - -```cpp - subresourceRange.levelCount = texture.mipLevels; - vks::tools::insertImageMemoryBarrier( - copyCmd, - texture.image, - VK_ACCESS_TRANSFER_READ_BIT, - VK_ACCESS_SHADER_READ_BIT, - VK_IMAGE_LAYOUT_TRANSFER_SRC_OPTIMAL, - VK_IMAGE_LAYOUT_SHADER_READ_ONLY_OPTIMAL, - VK_PIPELINE_STAGE_TRANSFER_BIT, - VK_PIPELINE_STAGE_FRAGMENT_SHADER_BIT, - subresourceRange); -``` - -Submitting that command buffer will result in an image with a complete mip-chain and all mip levels being transitioned to the proper image layout for shader reads. - -### Image View creation -The Image View also requires information about how many Mip Levels are used. This is specified in the ```VkImageViewCreateInfo.subresourceRange.levelCount``` field. - -```cpp - VkImageViewCreateInfo view = vks::initializers::imageViewCreateInfo(); - view.image = texture.image; - view.viewType = VK_IMAGE_VIEW_TYPE_2D; - view.format = format; - view.subresourceRange.aspectMask = VK_IMAGE_ASPECT_COLOR_BIT; - view.subresourceRange.baseMipLevel = 0; - view.subresourceRange.baseArrayLayer = 0;
