mattdesl/glsl-fxaa

This is a WebGL implementation of Fast Approximate Anti-Aliasing (FXAA v2) for use with glslify, providing a screen-space anti-aliasing technique particularly useful in WebGL where MSAA support is limited. The library offers both standard and optimized versions for mobile GPUs, with the optimized variant reducing dependent texture reads from 9 to 4 by computing coordinates in the vertex shader. It's designed for WebGL developers creating 3D scenes or post-processing effects who need high-quality anti-aliasing without native MSAA support.
