The intention is to create a small, portable library that can be used to deterministically generate content at runtime for applications such as games. Because it's MIT-licensed, you have very minimal requirements for your use of the library. While performance should be a goal, currently effort is being spent primarily on implementing useful algorithms.
It was inspired by reading about .kkrieger, and thinking how I wish some of these bloated games I install would use these techniques. What if there was a nice, well-licensed library that game developers could use, with some examples of ways to generate pretty textures?
Perlin noise as GL_LUMINANCE texture, using different seeds:
Three Perlin noise outputs as R,G,B channels in GL_RGB texture, using different seeds:
Turing reaction-diffusion system outputs with varying input factors, as GL_LUMINANCE texture:
Two-stage Turing reaction-diffusion system outputs with varying input factors, as GL_LUMINANCE texture (Da = .125, Db = .03125)
Meinhardt reaction-diffusion system outputs with same seed but varying Dg factor, as GL_LUMINANCE texture (Dr = 0.0, Ds = .08, c = .002, gamma = .01, 16000 iterations)
From there, ideas for future work:
Feel free to drop me an email at anholt@FreeBSD.org if you're using the library (I'd love to know), would like to see a CVS repo (I'm meaning to do this soon anyway), or have links to docs on great methods for procedural content generation.
