SDF vs MSDF vs Slug vs Rive vs Texture Atlas: GPU Text Rendering Explained
How do I choose a text rendering algorithm between SDF, MSDF, Slug, Texture Atlas or Rive? Text looks simple until you have to draw it yourself. A letter is not a picture, it is a set of outlines: closed loops of straight lines and Bezier curves, filled according to a winding rule. Drawing that on a CPU into a bitmap is a solved problem. Drawing it on a GPU, crisply, at any size, under any 3D transform, while the text changes every frame, is not. Most engines dodge the hard version by baking glyphs into textures ahead of time and living[…]

A Comprehensive Introduction and Overview of Gaussian Splats, Part 2 – Creating Gaussian Splats: From Photos to a Trained Model
In Part 1 we took the term apart. We covered what "splat" means, what "Gaussian" means, where the technique came from (radiance fields, then NeRFs in 2020, then the INRIA 3D Gaussian Splatting paper at SIGGRAPH 2023), and why anyone bothered to invent it in the first place. The one-word answer was speed. A NeRF[…]
Don’t let your proprietary code and IP leak to the cloud. Use on-prem air-gapped code audits.
A few days ago the mathematician Tristan Buckmaster, of NYU’s Courant Institute, published a statement about a result he and Levent Alpöge had spent roughly a year chasing: finite-time blowup for several equations in fluid dynamics, the kind of problem that sits next to a Clay Millennium Prize. Through the whole project they state they worked with LLMs, including OpenAI’s Codex, and they put every draft into their Codex sessions as they went. Then a rumor started that someone had cracked a major open problem. Buckmaster was told an internal OpenAI model had produced a competing proof, around 100 pages, on[…]
