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 :)

I am privileged to have sat down with @jimkjellin.bsky.social and Andreas Larsson from Machine Games and @geforce-jacobf.bsky.social to talk about the tech behind Indiana Jones and The Great Circle on PC. How was full RT integrated? RTGI? A lot of awesome info here! Enjoy!

In Filament we use a technique similar to Doom's (the linked comment should interest you). We only allow one layer of refraction however for performance reasons. Refractive objects neither opaque nor transparent, we just draw them between those passes.

I built a basic compute raytracer in Unity to test and play with @jbikker.bsky.social's tinybvh. I think it's a good example of utilizing the library as well as a decent starting point for anyone interested in building a wavefront pathtracer in Unity.

A while ago I did a writeup on some interesting observations I've made with regards to the Jacobi method, in particular for numerically solving the Poisson equation.
It's not too flashy, but you might find it interesting. Fancy recurrence relations inside!

Alt: The Jacobi method is typically quite slow and useless in isolation, but it has lot of interesting properties that's useful in other contexts, so it's worth studying.

My latest article is about one of my favorite techniques in graphics - Müller's method of Polar Decomposition.
It also details some variations, including one which is ~2x faster to compute with more regular convergence.

New in tiny_bvh.h today:
- 4/8-wide BVH layout
- Conversion (collapse) from BVH2 to BVH4/8, Wald-style
- Basic intersect functions for both layouts.
BVH4 will primarily feed a fast OpenCL intersection function, but the CPU may also benefit. BVH8 will be used for CWBVH.
