A comedy short film I’ve been working on with friends on-and-off over the past few years is finally out. It’s ~20min, very lighthearted in tone, and free, so go have a watch!

Here's something I've been working on that's (hopefully) useful for others: a single-header spherical harmonics support library for HLSL 2021

Some of what I’ve been working on at Activision for the past while: we’ve just presented a paper at I3D on using zonal quadratic SH (ZH3) as a compact encoding for irradiance. We show how you can get more quality out of linear SH by hallucinating extra coefficients, and also how you can encode ZH3 probes in 16 bytes, getting a lot of the quality of quadratic SH in a very compact footprint. The paper is at http://torust.me/ZH3.pdf, and there’s a ShaderToy at https://www.shadertoy.com/view/Xfj3RK.
