TWGL – A tiny WebGL helper library

In plain words

TWGL is a lightweight JavaScript library that simplifies WebGL development by reducing verbose API calls. It provides core helper functions for setting up shaders, buffers, attributes, and uniforms, making it ideal for developers who want to work directly with WebGL at a lower level without the overhead of larger frameworks. The library works with any math library that stores matrices as Float32Arrays or JavaScript arrays.

From the sources

This library's sole purpose is to make using the WebGL API less verbose. If you want to get stuff done use three.js . If you want to do stuff low-level with WebGL consider using TWGL . WebGL is a very verbose API. Setting up shaders, buffers, attributes and uniforms takes a lot of code. A simple lit cube in WebGL might easily take over 60 calls into WebGL. There's a few extra helpers and lower-level functions if you need them but those 6 functions are the core of TWGL. You are welcome to use any math library as long as it stores matrices as flat Float32Array or JavaScript arrays. See the examples. Otherwise there's a few different versions TWGL's is an attempt to make WebGL simpler by…from twgljs.org
