- the post introduces new D3D12 features available with latest win10 preview version
- DirectX Raytracing Tier 1.1 introduces ExecuteIndirect, dynamic raytracing PSO additions and Inline Raytracing
- Inline Raytracing allows RayQuery to be called from every shader stage
- DirectX Mesh Shader are similar to nvidia mesh shaders, allowing more flexibily in the vertex processing pipeline
- DirectX Sampler Feedback allows the recording of which parts of textures have been accessed
- enabling more fine grained streaming and texture space shading scenarios
- the video explains the basic of shaders in Unity for beginners
- the ARM developed sets of samples to showcase best practices for Vulkan on mobile is now open-source and part of Khronos
- article has list of samples and tutorials for a number of different areas
- Khronos published a unified Vulkan Samples Repository
- all samples are based on the same framework and have been reviewed and are maintained by Khronos
- the article shows the Unity shader implementation for stylized and unlit grass
- a geometry shader is used to spawn a variable number of grass blades based on camera distance
- grass movement by wind is emulated with a displacement texture
- starts by showing how to create a small 2D world procedurally
- small overview of explicit vs implcit surface ray tracing
- then shows the steps used to render a procedural mini planet
- including ocean waves, mountains and clouds
- summary of SIGGRAPH 2019 for a hybrid solution between temporal anti-aliasing with adaptive ray tracing
- using heuristics to detect when adaptive ray tracing provides the best improvements
