WebGL Generative Particles

This library is a Work In Progress. Feel free to request features, report bugs, or contribute. We aim to keep the APIs stable, though some changes may occur.

"webgl-generative-particles" is an efficient WebGL-based generative particle system simulator designed for both React and vanilla JS applications. This system follows the mouse pointer, providing interactive and dynamic visual effects. It offers seamless integration with React (including React 18 and beyond) and Next.js, making it an ideal choice for modern frontend development. The simulator is customizable, compatible with various frameworks, and delivers high performance and real-time rendering for progressive web development.

Features

✅ Fully Treeshakable (import from webgl-generative-particles/react)

✅ Fully TypeScript Supported

✅ Leverages the power of React 18 Server components

✅ Compatible with all React 18 build systems/tools/frameworks

✅ Documented with Typedoc (Docs)

✅ Examples for Next.js, Vite, and Remix
