- the article provides a visual explanation of what an optimal transport problem is
- presents how the problem can be solved a lot simpler in 1D
- extends on this insight to present how a multi-dimensional problem can be sliced and approximated in multiple 1D steps
- the article describes the concept of render-bundles and how they can be used to reduce CPU overhead
- presents what changes are backed into the bundle and how updating referenced resources enables flexibility beyond static scenes
- code examples and internals are discussed in WebGPU terms but apply to other APIs as well
- The author updated his library for spherical harmonics and zonal harmonics
- added GLSL shader variation and shader toy
- additionally, the update fixed several bugs and made improvements
- the article presents a look into the internals of the gfx-rs wgpu implementation
- demonstrates the limitations of the implementation in terms of multithreaded uses
- shows what changes were made to reduce lock-contention and how the implementation might change in the future further
- short blog post lists a couple of tricks to use when writing shaders for higher performance
- additionally provides a small trick on how to reuse data between iterations when using shaderToy
- the blog post shows how to use Nvidia-specific intrinsics with D3D11 and D3D12
- how to use them from shaders and how to verify that the hardware supports it
