I haven't posted here yet, so let me share some of my recent work. Here is my "Crash Course in Deep Learning (for Computer Graphics)", available on GPUOpen: gpuopen.com/learn/deep_l...

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!

Classics 😊

I will be presenting our "GATE: Geometry-Aware Trained Encoding" at HPG on Wednesday at 9:50AM. See you all in Copenhagen soon! Paper link is here: diglib.eg.org/bitstream/ha...

I'll buy your book

This is the kind of story I needed to hear today 🙂. The power of mexican cuisine 💪

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 · Jun 10

(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.

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!

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.

You're within the order of magnitude of quarter res still. We can agree

I received a patent trophy! Big thanks to my friends and colleagues who helped me along the way!

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 :)

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

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

I wrote a new article, this time exploring a bit how some games handle refraction.
I discovered quite a few interesting tricks !

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.

The advice I got ca. 2008 was to put network cables inside of walls when building new home, connecting all rooms for ultimate Internet access. Only if we knew the WiFi will be the future 😅

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...
