REGL

A functional, declarative wrapper that replaces the WebGL state machine with predictable, stateless draw commands.

REGL simplifies WebGL by treating GPU operations as pure functions. It eliminates the standard state machine headache: you define shaders, uniforms, and attributes in a single configuration object. This functional approach prevents side-effect bugs and cuts boilerplate significantly (often by 70% or more). It is the go-to tool for high-performance visualizations and custom engines where direct pipeline control is required. By mapping JavaScript props to GPU state, REGL makes complex techniques (like instanced rendering or multi-pass effects) modular and easy to debug.
