Here’s highlights of what I was able to capture with my cameras and telescopes in 2024. An eclipse, Aurora, rockets, and SO MANY deep sky objects. It was quite a year, but I have even more planned for 2025. I’m just getting started.

My new blog post explains spectral radiometric quantities, photometry and basics of spectral rendering. This is part 2/2 in a series on radiometry. Learn what it means when a light bulb has 800 lumen and how your renderer can account for that. momentsingraphics.de/Radiometry2Pho…

Surface-Stable Fractal Dithering: bit.ly/3E7zFN8

vik OpenAI recently tried to scrape gigabytes of data from our website which caused our server to go down multple times. They somehow seem concerned when its stolen from them, not so much when they do it. techcrunch.com/2025/01/10/how…

🚀 Introducing DiffusionRenderer, a neural rendering engine powered by video diffusion models. 🎥 Estimates high-quality geometry and materials from videos, synthesizes photorealistic light transport, enables relighting and material editing with realistic shadows and reflections

Also GOOD: float c; if( x<0.5 ) c=a; else c = b;

Using trained algorithms in interactive colour grading: bit.ly/41cIvm6

We just shipped the latest Python 3.14 alpha (3.14.0a5) to uv and python-build-standalone. This is the first release that includes the tail-calling interpreter. Our initial benchmarks show a ~20-30% performance improvement across CPython.

uv is one year old today. Hard to believe its only been a year. The growth, adoption, and impact surpassed my wildest expectations. Happy birthday, uv! 🥳

I'm thrilled to share a JCGT paper, "GPU Friendly Laplacian Texture Blending." It uses simple image processing and computational photography techniques to smoothly blend textures and materials while preserving local contrast and texture details without ghosting or blurring. 1/3

We are pleased to announce the release of the new OpenColorIO Configuration(s) for ACES 2.0: buff.ly/guty9Fh

OpenColorIO 2.4.2 has been released and ACES 2 support is now officially available with it! buff.ly/hv1MuDE

Not colour science related but of interest in this day and age: Prompt Engineering by Lee Boonstra from Google kaggle.com/whitepaper-pro…

Big area of investment for our upcoming type checker: world-class diagnostics / error messages, inspired by rustc. We can pull in rich context from across your codebase. All Andrew Gallant approved.

Thanks to the great work by Michael Mauderer, CLF support is now available in Colour! colour-science.org/posts/support-…

Alongside the preview release, we're also shipping an official VS Code extension. And you can use `ty server` directly in any editor that supports the Language Server Protocol (Neovim, etc.).
