A new language for dynamic, programmable vector graphics

WEAVEFONT is a programming language for creating vector graphics — originally designed for programmable typefaces, but powerful enough for static images, generative art, and real-time animations.

Inspired by the powerful and innovative METAFONT and reimagined for modern graphics pipelines, WEAVEFONT lets you define visual forms algorithmically and renders them in real time using OpenGL. That means high performance, fluid animations, and native interactivity — on desktop or in the browser through WebAssembly.

Key Features:

• Programmable vector fonts with full parametric control.
• Real-time rendering via GPU acceleration (OpenGL/WebGL)
• Lightweight and portable: just drop in a single .c and .h file in your project.
• WebAssembly-compatible: no external dependencies
• Free software: made for openness and community
