Ever wondered what happens when you extrude a face? This is the visualization of the internal data structure used inside of Valence 3D.

A few years back, I wrote a Unity package for fracturing non-convex meshes. For the past few weeks, I've been attempting to port the code to #threejs (with some help from ChatGPT). Still buggy and unoptimized, but excited to finally have a result!

The Alien.js v1.2 motion blur is based on Garrett Johnson's Per-Object Motion Blur Render Pass, updated shader replacement and blue noise jitter with a texture map.

Great article by Don McCurdy (@[email protected]) on the theory, concepts, and practice of emission and bloom with a brief background on relevant light transport and color theory.

It's not often that you see a small indie game build their own engine with state-of-the-art light transport and rendering; I'm really looking forward to Tiny Glade 🏰🌿 Wishlist on Steam ✨'s Tiny Glade!

The three-gpu-pathtracer refactor is almost done! It wound up being a lot bigger than I thought but it should be much easier to use. Here's a comparison of the README setup instructions for a basic usecase. From 80 lines down to 20!

Release soon!

Epic added a new denoiser for Path Tracing this week, NFOR, specifically designed for sequence rendering, it appears incredibly stable compared to the default denoiser, with more normal looking noise vs the insane warbling with the default.

We CT scanned an Apple Vision Pro! We also scanned two Meta headsets. Here’s what we found inside, and what it says about the two companies’ approach to AR/VR and to hardware development in general. 🧵

New blog post! 'Meshlet triangle locality matters', in which we discover an unexpected efficiency property of mesh shaders on NVidia hardware, and attempt to deal with it.

Retweets appreciated!

The next lecture in my raytracing course is all about PBR materials. We'll implement basically the standard glTF material, with Cook-Torrance BRDF, GGX distribution, etc.

This uses multiple importance sampling combining cosine-weighted hemisphere, VNDF and direct light sampling.

Managed to improve the performance and quality of SSGI. Now it doesn't use dithering, but a wider uniform sampling. Also caching more stuff in groupshared memory. Still have to apply too much blur, so sadly much of the shape of shadows is lost. But pretty stable in motion now.
