Float to R8_UNorm conversion has a permitted tolerance of 0.6ulp in the DX spec. 0.55/255 on some GPUs rounds down to 0 and on others rounds up to 1/255. Dangerous behavior when R8_UNorm NumFramesAccumulated=0 is used by a denoiser to mark invalid history... microsoft.github.io/DirectX-Spec...

I decided to open source my implementation of Surfel Radiance Cascades Diffuse Global Illumination, since I'm not longer actively working on it. Hopefully the code can serve as a guide to others who can push this idea further :) github.com/mxcop/src-dgi

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-...

In our next Tiny Glade update we'll bump the light limit from 32 to 32k while keeping the cost more or less the same. The small limit has been a cop out, as we didn't quite know how to render huge numbers of (screen-space) shadow-casting lights without severe performance degradation.

Thread divergence during constant buffer reads can have a big perf impact, this presentation discusses how to detect this on NVidia GPUs using GPU Trace and Shader profiler. Also shows how useful access to ISA is for understanding what the shader does under the hood. www.youtube.com/watch?v=HSsP...

Here's a recording of my Tiny Glade presentation from the Graphics Programming Conference 2024: www.youtube.com/watch?v=jusW... It's an any% speedrun of our GPU-driven rendering, shadows, global illumination, water, and DoF, involving a few weird tricks.
