rreusser/glsl-fft

This project provides a GLSL-based Fast Fourier Transform (FFT) implementation for processing two complex matrices in WebGL shaders, designed for developers working with GPU-accelerated image processing, signal processing, or WebGL applications who need to perform FFT operations directly on the GPU. The library includes both JavaScript setup code and GLSL fragment shaders to execute multi-pass FFT computations on power-of-two sized textures.
