I'm a little late to the party on this one since it's from January, but I just read this great blog post by Jure Triglav walking through implementing surfel-based global illumination. It's got a bunch of really cool interactive toys/visualizers!

Here is a new blog post of mine, where I dive deep into the theory and math behind ReSTIR GI.

Big thanks to @nmkettunen for verifying the theory, reviewing the article, and catching a key detail I had missed.

I put all of my Ray Tracing Gems chapters in one place where you can download them, extracted from books into separate PDFs: https://t.co/AOGFePRgoG
There is:
1. "Ray Traced Shadows"
2. "Reference Path Tracer"
3. "Refraction Ray Cones"
4. "Many Lights With Grid-based Reservoirs"

I wrote a "Crash Course in Deep Learning" for people (mostly) in computer graphics who want to start with deep learning. The link is: https://t.co/diqkV3bxFX
Have fun!

Very nice video explaining visually how GI and Radiance Cascades work: https://t.co/ovpe3v8rXY

I spent some time the past couple of weeks having fun with workgraphs and I've put together a quick tutorial on how to start using them using a practical example. https://t.co/s7KaZtngLB

It's finally here.

Explains how I learned Vulkan and wrote a small game engine with it in 3 months.

It's huge. Hopefully you'll find it useful. :)

New blog post: Demystifying multiple importance sampling

It is a simple thing that turns out to be confusing to a lot of us rendering engineers. I try to explain it in detail here with path-tracing examples!

Excited to share our Eurographics short paper "Real-time Seamless Object Space Shading"! We do ReSTIR in Object Space which is decoupled from screen space shading, elevating the scalability of your render pipeline. Code: https://t.co/W2NqSEOO44

🎇 🥂 Final blog post of the year! @dbalthazr Explains a whole bunch of tricks he pulled to get our Global Illumination system looking as sweet as it does! https://t.co/EnyPyPV71B

[Kostas Anagnostou @KostasAAA]

ReSTIR based dynamic diffuse global illumination, discussing ray generation, temporal and spatial reuse, irradiance caching and denoising, good read: https://t.co/zDLykQYD4Z

[Kostas Anagnostou @KostasAAA]

I made an attempt at a Maths-free, qualitative introduction to ReSTIR for direct illumination, lots of pretty pictures. https://t.co/q0x108pdia

The OpenPBR repo is now publicly available! A subproject of @MaterialXcg, OpenPBR provides an artist-friendly new open source shading model to bridge the gap from one software package to another. We encourage community input - read more on the blog: https://t.co/wzrCIBMhzt

Presenting: Voxel global illumination demo in three.js (Link in comments)

Uses voxelization in a worker thread, blue-noise powered stochastic sampling, and A-torus denoising to create a realtime GI solution that supports completely dynamic scenes. It runs at 60-80fps (w/out recording software) on an M1 mac!

People asked for ReSTIR resources, in addition to the original paper https://t.co/mmjXQe7Jet and "Gentle Introduction" https://t.co/aZBmThFPnF, there're quite a few blog posts: https://t.co/kwdxGzjhyd, https://t.co/EX6hAU3PUH, https://t.co/N47Xq42NlI, https://t.co/zHMdolcWqf 1/2
