Variable-width Bézier curves (2025)
Summary
A technical blog post by Luther Tychonievich exploring variable-width strokes for Bézier curves in 2D graphics. It covers pressure-based stroke models (circular offsets), line vs. spline rendering, de Casteljau and Horner algorithms, hodographs, stroke outlines, and CPU/GPU implementations, with notes on export formats and an open-source licensing approach.
