A gentle reminder my MLPZen project is up on GitHub. You get: - MLP inference and training in standard HLSL, in-line anywhere in your shaders - 2D and 3D Hash-grid - Adam optimizer - Dx12 sample app - Link: github.com/boksajak/MLP... Looking forward to how people will use this!

I made a game! Do you like playing your favorite arcades but feel like there's not enough ray tracing? You can now play my "bin packing" classic with full path tracing. Open source and free (executables in the bin folder): github.com/boksajak/Bin...

My MLPZen project comes with a sample showing a simple neural texture compression (NTC). You don't need a complex vendor-locked SDK with proprietary extensions to start experimenting with NTC for your game. This project is pure DirectX 12/HLSL. Github: github.com/boksajak/MLP...

Forgot to post it here, but I recently went through @boksajak.bsky.social's great Crash Course in Deep Learning. To make sure I understood everything, I implemented it in Odin. This straightforward CPU version is very slow as you might expect, but also easy to follow. github.com/wookie41/odi...

One group is stochastic friendly to ray tracing while the other group is more suited to rasterization pipeline. I agree though that over time, stochastic RT approaches will universally be the high end option

Just a good balance for performance. Feel free to try larger networks, but tou may need to increase number of features per level of the hashgrid as well

Jakub Boksansky @boksajak.bsky.social · 10/06/2025

(1) Yes, we mention that as "clustering" for future work (2) We could have a fixed MLP serving as a decoder, or non-neural function reading stuff stored on geometry with GATE.

Lol, and you need to use the advance lever to move the "film" to the next frame. Perfect for people who want the inconvenience of using film with none of the benefits. I am glad it exists and that I don't have to use it.

as a hotfix: Try doing some programming with a truly horrible language™️ and/or platform few decades old and suddenly the modern tools will look like a blessing. For a while at least. YMMV

After many weeks of effort I finally have radiance on screen now! I’ve still got issues mostly related to my Surfel Acceleration Structure, however I’d say the results are already looking quite promising. It has kind of a hand painted look to it now :)

yes, you cast one more shadow ray, but you may be able to forgo casting the same shadow ray second time for shading when the selected light is the same as initial candidate

What urges you to write your own path tracer? Do you prefer your pixels home-made? Is it the thrill of GPU timeout debugging? Is it insanity? Tell me why we do it.

tiny_bvh has been updated to 0.4.0. Changes: 1. speedtest reports compiler, CPU, lib version. 2. Performance is improving but Embree remains KOTH. :( 3. New: BVH optimizer! 4. New: Better test scene now included. Win64-only; the old one remains the default. Next up: SBVH! github.com/jbikker/tiny...

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.
