Instead of creating per-object descriptor sets for rendering multiple objects, this example passes descriptors at command buffer creation time.

#### [03 - Multiview rendering (VK_KHR_multiview)](examples/multiview/) #### [03 - Inline uniform blocks (VK_EXT_inline_uniform_block)](examples/inlineuniformblocks/)
Makes use of inline uniform blocks to pass uniform data directly at descriptor set creation time and also demonstrates how to update data for those descriptors at runtime.
#### [04 - Multiview rendering (VK_KHR_multiview)](examples/multiview/)
Renders a scene to to multiple views (layers) of a single framebuffer to simulate stereoscopic rendering in one pass. Broadcasting to the views is done in the vertex shader using ```gl_ViewIndex```.

#### [04 - Conditional rendering (VK_EXT_conditional_rendering)](examples/conditionalrender) #### [05 - Conditional rendering (VK_EXT_conditional_rendering)](examples/conditionalrender)
Demonstrates the use of VK_EXT_conditional_rendering to conditionally dispatch render commands based on values from a dedicated buffer. This allows e.g. visibility toggles without having to rebuild command buffers ([blog post](https://www.saschawillems.de/?p=3098)).

Uses the VK_EXT_debug_marker extension to set debug markers, regions and to name Vulkan objects for advanced debugging in graphics debuggers like [RenderDoc](https://www.renderdoc.org).
