Super happy and honored to share that our paper "BSP-OT: Sparse transport plans between discrete measures in log-linear time" won a *Best paper award* at SIGGRAPH Asia 2025!
If you are here, come see my presentation about this work Wednesday afternoon!
Many thanks to the award committee!

My absolute favorite (and hands-down the most used) spatial warp in Keeper is the fractal. Our morph tech supports both Mandelbulb and Quaternion fractals. It's addictively cool and I could play with this all day long. :)

I reopened my project for the first time in 6 months... I barely remember which side is up. I told myself, "Do the first thing that cross your mind":
If there is geometry under a light, and its cameraGain is set to zero, the light and the geometry become invisible to camera rays.

Oh no, I managed to build my game for mac, but launching it fails, because wgpu metal backend doesn't yet support multi-draw-indirect-count (which I can easily emulate) and push constants (which are a huge pain to emulate).
Sooooo do I use moltenvk or what

All this profiling mess made me kinda tired of the voxel raytracer project, so I'm back to my main game, trying to build it on Mac, which will make it possible to use XCode profiling as well.
Of course it doesn't build for a ton of reasons, working on fixing those rn 🥲

Another status update: the actual profiling thing (GPU Trace mode) doesn't support my GPU (GTX 1060). Oh well.

The z-buffer and depth testing (aka z-testing) have been the dominant way of hidden surface elimination for over 50 years, introduced but not implemented in W. Straßer's PhD thesis in 1974, and actually implemented in Ed Catmull's PhD thesis in the same year. 1/4

found a fascinating artifact from the 00s while looking into circle/sphere packing www.redneckpoolheater.com
it's actually really cool because here they have the additional constraint of having to be able to form a network of connected pipes, the tube runs are in pairs to have a return route

about the reuse of the data structure from the sphere packing, reinterpreting it as a grid-based raytracing acceleration structure:

this is a little underrated cool indexbuffer optimization trick that i seen several times (this screenshot from Unreal, as it is a public reference, but i seen its alternative in custom engines multiple times).

I'm back from vacation (and food poisoning...), so my tree impostor adventures continue. Now precomputing & rendering tight octagonal impostor bounds (instead of full-bbox quad), which saves another ~0.7ms per frame in the scene with ~30k trees!

The demo I’ve been working on is finally online:
ludicon.com/sparkjs/gltf-demo/
It demonstrates the benefits of real-time texture compression in 3D web apps. It allows you to compare models using traditional KTX2 textures (UASTC and ETC1S) with the same assets compressed as AVIF + Spark.
