- the second part of the blog post series covering raytracing implementation with compute shaders presents the results of splitting the acceleration structure into two levels
- presents an overview of the implementation, performance comparison
- additionally shows that two-level separation provides additional flexibility advantages
- Vulkan extension for Variable Rate Shading (VRS) has been released as VK_KHR_fragment_shading_rate
- adds the necessary API and SPIR-V extensions
- latest PIX update adds support for visualizing the GPU execution of command list from a single ExecuteCommandLists call
- adds support for showing the resources that belong to each descriptor in a heap

- the author presents an overview of his raytracer setup
- explains the problems encountered and the current state
- provides an overview of how to trace the Ptex textures on the GPU
- the Unity article explains how to integrate multiple cameras into a scriptable render pipeline
