I think I finally "understood" theory of relativity. The graphics programmer version: It's really just some normal map decode math and tonemapping :) Thread...

Stripy Anti-aliasing shadertoy.com/view/l3VcWG Stripes can be tricky to learn at first, but it's a good stepping stone for more complicated scenarios, so it felt necessary to include

Great visual to understand trigonometric functions.

The CUDA programming guide docs.nvidia.com/cuda/cuda-c-pr… is worth studying, even if you're not programming in CUDA. A lot of this knowledge is transferable to DX12/Vulkan compute shaders, especially the GPU architecture/best practices/performance guidelines parts.

NEW GM Shaders: Gamma! mini.gmshaders.com/p/gamma How computers handle lighting and specifically gamma correction. This is a simple introduction to more accurate color blending and lighting

I wrote a blog post on my implementation of the Surfel maintenance pipeline from my Surfel Radiance Cascades project. Most of what I learned came from "SIGGRAPH 2021: Global Illumination Based on Surfels" a great presentation from EA SEED :) m4xc.dev/blog/surfel-ma…

This year the "new" DirectX 12 graphics API, becomes 10 years old (Vulkan becomes 9). Feeling old yet?

min/max SDF -> either inside or outside is broken. Subtracts keep the inside fine, but the outside is incorrect. Union keeps the outside correct, but the inside is incorrect. Incorrect == not the actual distance to the surface. Conservative distance is not always good enough.

Seb wrote a fantastic article exploring how to make mat mul go fast on AMD GPUs. This is a deep dive into both the algorithm and hardware, with great visualizations. He is also looking for work and I only have good things to say about him, so hire him! seb-v.github.io/optimization/u…

Hope it went great Victor! I’d love to have a chat to compare notes sometime.

My talk from Better Software Conference last week is up on youtube. I present my findings on thread synchronization and job systems that I learned while parallelizing the physics solver. youtube.com/watch?v=Kvsvd6…

Awazing talk! Another technique (common in GPU) is persitant jobs: - let atomic C = 0 - fill machine->N jobs: - do work - prev = InterlockAdd(C, 1) - while (prev != N-1) spin - if (prev==N-1) prep next loop & break spin. - all threads persistent and require no schedule!
