(WebGL) Volumetric Light Approximation in Three.js - Blog - (BKcore) Thibaut Despoulain

This article will be covering the technique behind the volumetric light approximation (VLA) aka godrays I used in my latest OpenGL project to simulate sun shafts, but this time in WebGL, with a point light. Check out the demo and the code after the break. Update Following the recent changes in Three.js rev50/dev, the godrays shader provided on my github now uses unflipped v coordinates. If you use
