I am happy to announce publication of my chapter titled "Real-Time Neural Network Implementation for GPUs" in GPU Zen 4 book, available now.
Chapter comes with full MIT-licensed source code, available on Github here: github.com/boksajak/MLP...
The book is available on Amazon.

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):

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.

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 :)

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.
