- The author is developing a WebGPU animation renderer for web-based animations and implemented a technique for rendering TTF fonts, which recently expired from a Microsoft patent.
- TTF fonts use glyphs composed of paths and quadratic splines defined by start, end, and control points, with paths having clockwise or counterclockwise directions for filling or cutouts.
- The rendering technique by Loop and Blinn uses triangles to represent splines on the GPU, allowing shaders to efficiently determine pixel inclusion based on UV coordinates, enabling high-resolution font rendering without complex calculations.
