- the new Vulkan extension allows developers to express local dependencies between sub-passes so that drivers can stay on-chip memory for tiled hardware
- blog post explains the extensions, how to post existing applications to use the new extension
- Khronos released two new SPIR-V extensions
- the first extension guarantees reconvergence behavior to require the behavior many programmers’ intuition assumed to work
- additionally, a new extension allows correct divergence handling within a quad
- the blog post explains the previous issues and how the extension solves them
- the blog post describes the history of Portals and BSP trees
- expands the ideas to more modern concepts and suggests the applicability of GPU based solutions
- the article presents issues with moving averages and suggests using binomial averages instead
- shows data examples to highlight the issues and explain in frequency domain why they happen
- the article shows how PIX can be used to debug WebGPU applications
- shows what is required to attach PIX, get debug-marker output, as well as frequent issues
- the author discusses a method to use indirect drawing to draw a dynamic number of instances of each type on the GPU
- The article provides an overview of the implementation (with code examples)
- additionally provides a couple of optimizations and future development steps
- the blog post provides a detailed walkthrough of the implementation of a caustics effect using WebGL
- shows the different elements the effect is made up of and how to simulate the different phenomena
- intermediate samples are presented as interactive WebGL examples
