Left: 1 spp pathtrace Right: Temporal accumulation with reprojection Accumulation works with camera movement using a classic rejection test: ID, depth, and normal threshold. Hopefully the video compression doesn't make it impossible to distinguish :)

Implementing the filtering (denoising) part of the SVGF paper in my #rustlang #webgpu library. Washed out texture is due to the missing albedo demodulation. Far from perfect, but it's moving in the good direction!

Re-using the first iteration of the a-trous filter in the history definitely helps. Will need to work on the ghosting, but the flies hurt my eyes a little more right now :D

Added shader hot reload to Loupiote (pathtracer using the Albedo library). The temporal accumulation yields a beautiful transition between pre/post shader editing :) GLSL is compiled to Naga module (with a small Naga GLSL parsing fix)

More work on Albedo & Loupiote. Added rough compositing with albedo modulation. Not accurate yet, need to pass more data to the compositing pass. Also need to work on the temporal rejection more :) Real time pathtraced using #webgpu and #rustlang, no RTX

Started migrating my BVH to CWBVH using tinybvh. Didn't expect to hit that many issues with the GLSL port 😀

CWBVH is almost fully working now, brought back the TLAS as well. Once I am fully done with the CWBVH and tinybvh-rs make it to stable, I will finally fix those denoised colors being wrongly demodulated/remodulated.

Not perfect yet, but the CWBVH traversal is finally bug free! 🎉 Will try to get tinybvh-rs 0.1.0 ASAP

tinybvh-rs 0.1.0-beta.2 is out: github.com/DavidPeicho/ti… Major bug fix for the CWBVH nodes slice. Need to think about the refitting API before a stable release. This library would not exist without the original tinybvh, as the name "tinybvh-rs" suggests :)

More denoising work: Less fireflies, but still quite a bit of ghosting!

From now on, I will try to show more rust/webgpy raytracing directly on bsky, follow me there: bsky.app/profile/davidp… Progress of the day below!

I have a #rustlang library wrapping C++ code (tinybvh) using cxx. Any chance that can be used in another library compiled to WASM?

Great opportunity to give Wonderland Engine a try!
