Noise Graph allows you to graphically design libNoise modules, preview data as raw numbers or as image, and when you are satisfied with results generate C++ class ready to use in your application.
noiselib is a Python library inspired by the C++ libnoise. noiselib strives to provide a 'Pythonic' interface, without sacrificing speed. The noise generators are implemented using the C Python API.
A general-purpose library that generates three-dimensional coherent noise. Useful for terrain generation and procedural texture generation. Uses a broad number of techniques (Perlin noise, ridged multifractal, etc.) and combinations of those techniques.
A space sim game engine project, using Ogre3D for rendering, libnoise for galaxy, system, planet, city, npc generation; the goal is seamless transitioning between space flight, atmospheric flight and ground walking, and high frame rate, of course...
