HLSL shaders * Added sample count to framebuffer create info * Removed no-longer used assets * Android build Removed no-longer used assets * Code cleanup and heavy refactoring Updated GLSL and HLSL shaders Use tangents stored in GLSL instead of calculating them in the fragment shader * Renamed textured PBR sample main cpp file * Use glTF assets Code cleanup and refactoring Updated GLSL and HLSL shaders Removed no-longer used assets * Use glTF assets Removed no-longer used assets * Android build files * Android build files * Use glTF assets Removed no-longer used assets * Fixed HLSL shaders * Android build files * Use glTF assets Updated GLSL and HLSL shaders Removed no-longer used assets * Use glTF assets Updated GLSL and HLSL shaders Removed no-longer used assets * Added flag to disable glTF image loading Useful for samples that use their own textures or don't use textures at all to speed up loading * Use glTF assets Code cleanup Use Sponza scene instead of Sibenik to better highlight the effect Updated GLSL and HLSL shaders * Updated Android build files * Removed left-over comment * Use Sponza scene for the SSAO sample * Removed unused code * Removed ASSIMP No longer required as all samples now use the glTF file format * Added missing vertex shader stage * Removed old ASSIMP-based model loader * Added support for loading external glTF images from ktx Android fixes for loading external buffer files * Scene setup * Added missing shader stages * Removed ASSIMP from build files * Fixed compiler warning * Removed ASSIMP from readmes * Android build files cleanup * Replaced ktx submodule with only the files required for this repo The ktx submodule was a tad too big and contained lots of files not required for this repo * Moved ktx build files into base project * Use glTF assets * Use glTF assets * Removed license files, will be moved to asset pack * Use RGBA textures * Use RGBA cubemp texture with face assignment based on original images Refs #679 * Android build files * Removed textures All textures will be moved to the asset pack * Ignore asset folders * Removed font Fonts will be moved to the asset pack * Link to gltf asset pack * Updated gitignore * Android build file
