Ray marching is a common approach to GPU-accelerated volume rendering, but gives biased transmittance estimates. My new #SIGGRAPHAsia paper (+code) proposes an amazingly simple formula to eliminate this bias almost completely without using more samples.

A couple barriers to C development are lack of a fast sorting library and a fast hash set and map. I've found these two libraries to be excellent at providing those. They are macro based, but I think the trade-off is worth it. Both work with C99.

A new article: Why CIELAB doesn’t improve median cut

It's a common misconception that CIELAB will instantly improve palettes produced by the median cut algorithm. Unfortunately it's not that simple.

📜 30fps.net/pages/median...

It gets pretty technical but I added some context to the intro.

This graph shows how eager each color space is to minimize lightness error. The X-axis represents median cut’s splits as it works its way through clusters until all palette colors have been found. The Y-axis shows the sum of squared lightness errors of the whole image, measured as CIELAB’s L∗.

I believe the low lightness weight is the main reason why median cut doesn’t work better in unscaled CIELAB than in sRGB.

🎄 Introducing our paper A Generalizable Light Transport 3D Embedding for Global Illumination lnkd.in/gQUMSAyV .
🙈 Just as Transformers learn long-range relationships between words or pixels, our new paper shows they can also learn how light interacts and bounces around a 3D scene.

So, I made a hair shader that doesn't require any specially made meshes or textures.

Initially I made this work by sampling many normal directions rotated around the hair strand direction, but I eventually got an approximation working that doesn't rely on multi-sampling.

"Return of the Obra Dinn" is seven years old this week.

For this not-particularly-special anniversary, here's a re-cammed and narrated timelapse of (nearly) all character creation, object modeling, scene posing, and general 3D work for Obra Dinn from 2015 to 2018:

I finally found the time and energy to make a new blog and write a couple of posts. This time I wrote about PBR content and game development principles. Both posts are quite different so hopefully people find something interesting on either one of them.

New article on my site: Better sRGB to greyscale conversion

The commonly used greyscale formula is slightly off when computed in gamma space but can it be fixed?

📜 30fps.net/pages/better...

A four-pane comparison of different formulas for greyscale conversion.
Top row: Linear sRGB (the correct way to do it), Gamma sRGB (the somewhat wrong "luma" formula).
Bottom row: CIELAB L* (a high quality option), and the new alternative gamma-space version.

Careful inspection shows the "Gamma sRGB" case is slightly dimmer at points than the others.

A quote from “Principles of Digital Image Processing” by Wilhelm Burger and Mark J. Burge. It shows weights that are a better fit for gamma-space greyscale conversion.

Computing the exact bijection of the optimal transport (OT) problem between very large point sets is completely untractable…

In our SIGGRAPH Asia 2025 paper: “BSP-OT: Sparse transport plans between discrete measures in log-linear time” we get one with typically 1% of error in a few seconds on CPU!

Happy to announce: ReSWD. Sliced Wasserstein Distances are quite powerful, but they perform a Monte Carlo (MC) integration (over random directions). During an optimization this can lead to noisy gradients due to variance.
