It uses GPU for image processing ant it is very fast (512x512 texture in less than 30 milliseconds). Now this program runs on my own engine, which supports GLSL shaders. This engine is LOVE-compatible, so, when LOVE supports shaders, this generator may runs on LOVE.
All textures and effects are seamless:
Cell noise+gaussian blur:
Perlin noise:
White noise:
Perlin noise+gradient mapping:
It may be used to create cool textures/detail textures and animated textures.
