Anyone has an idea how to create a filter to generate random noise for the GPUImage framework?

  • I guess I can consider this a feature request. It's a little late here for me to pull something together, but you're really looking for a GLSL ES implementation of a noise function. Check out the answers here: http://stackoverflow.com/q/4200224/19679 , particularly Stefan Gustavson's, for various noise implementations that could be used. None of these look particularly fast, so some tuning might be required for these fragment shaders. – Brad Larson May 04 '12 at 03:41

There's now a GPUImagePerlinNoiseFilter in the GPUImage framework based on the links in the thread referenced by Brad above.
