Crash Course in Deep Learning (for Computer Graphics)
If you're a graphics dev looking to understand more about deep learning, this blog introduces the basic principles in a graphics dev context.

I found it cool to hear the motivation for High-Frequency Learnable Encoding for NRC\NIRC\Neural Ambient Occlusion from the perspective of Kernel Machines!

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 :)

New blog post: Relativistic Quaternions
I briefly discuss what quaternions and dual quaternions must become in spacetime in order to represent physically meaningful motions.

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?

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).

I wrote about video game shadow techniques on my blog:

I've always liked different ways to draw shadows in games. I went and tried to find visually distinct examples and explain their differences. I hope you'll find it inspiring!
