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...
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.
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...

New papers day! Preprints of our „GATE: Geometry-Aware Trained Encoding“ to be presented at HPG and „Neural Visibility Cache for Real-Time Light Sampling“ currently on Arxiv are available here: boksajak.github.io/blog/Preprin... Kudos to co-authors Daniel Meister and Carsten Benthin. Enjoy!
I received a patent trophy! Big thanks to my friends and colleagues who helped me along the way!
Started putting together a new toy gfx framework based on python with pybind11 for directx12 etc.
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 :)

I wrote a new article, this time exploring a bit how some games handle refraction. I discovered quite a few interesting tricks ! www.froyok.fr/blog/2024-12... #gamedev #rendering
Refracting Pixels | Froyok - Léna Piquet
What started this article is that I wanted to support refraction in my realtime game engine (which you can learn more about here). I didn't find a lot of clear documentation on the subject, so I went ...

Remind me why folks prefer Aces tonemapper to the Reinhard (or do they)?
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...
Are you guys using HLSL 2021 in your shaders (e.g. for templates)? Is there anything preventing you from enabling HLSL2021?
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.
Raycasting to determine room size and sending sounds to 3 reverb channels fro close, medium and far reverb. And calculating pan for each reverb. I wanted this effect when you hear big space on one side and close space on the other (when you are near the wall). #sounddesign #gameaudio #gamedev
