iwo - A Typescript Webgl2 Physically Based Renderer

iwo is a physically based renderer written in Typescript. This project was created to learn how to create a forward rendering engine from scratch.

Demo

https://caboyd.github.io/iwo-examples/index.html

Installing

npm i iwo-renderer gl-matrix

This library requires a bundler like rollup and depends on gl-matrix. To use this library look at my example game Underwater Game
