Here is a new blog post of mine, where I dive deep into the theory and math behind ReSTIR GI.
Big thanks to Markus Kettunen for verifying the theory, reviewing the article, and catching a key detail I had missed.

Understanding The Math Behind ReSTIR GI
Recently, I had the pleasure of contributing to Nvidia’s Zorah project, the flagship demo for the RTX 50 Series GPUs. My primary role was to provide technical support for light transport in Zorah, whi...

New blog post! "Measuring acceleration structures", in which we will compare BVH costs on various GPU architectures and drivers and attempt to understand the details enough on AMD hardware to make sense of the numbers!

Measuring acceleration structures
Hardware accelerated raytracing, as supported by DirectX 12 and Vulkan, relies on an abstract data structure that stores scene geometry, known as “acceleration structure” and often referred to as “BVH...

This is a great presentation of the journey to use ML to improve GI in a shipped game. This is exactly the kind of NN applications that I find appealing, small NNs to improve specific parts of rendering systems. advances.realtimerendering.com/s2024/conten...

MegaLights release took me a bit by surprise. It was just a small prototype on a backburner, not planned to be showcased in UE 5.5. Now trying to catch up after the demo push, starting from writing the official docs which just went online: dev.epicgames.com/documentatio...
MegaLights in Unreal Engine | Unreal Engine 5.5 Documentation | Epic Developer Community
A whole new direct lighting path to place many dynamic and shadowed area lights in an Unreal Engine scene.

The first public release of tiny_bvh is now available from Github:
github.com/jbikker/tiny...
tiny_bvh.h is a single-header library without dependencies that rapidly builds and traverses a BVH for you. Have a look at the example to see how easy to use it is!
Feedback welcome.
