A library for generating coherent noise. It can be used to procedurally create natural-looking textures (such as wood, stone, or clouds), terrain heightmaps, and other things.

SharpNoise is a loose port of Jason Bevins' libNoise to C#. It adds some .NET features such as serialization and support for C# Object Initializer syntax. SharpNoise is published unter the terms of the Gnu LGPL 3.

SharpNoise has modules as building blocks for noise generators. There are two kinds of modules:

• Generator modules, which produce noise values and have no sources
• Modifier and Combiner modules, which take one or more source modules and produce a new output from the values of their sources.

These modules can be joined together in a tree of noise modules to generate very complex noise patterns.

To see how to use SharpNoise, check out the example applications:

• BeginnerSample is a very simple first sample that just renders an image from a noisemap and saves it as a PNG.
• ComplexPlanetExample generates a complex planetary surface, using over 100 connected noise modules.
• OpenGLExample renders ever-changing data from a simpler noise generator in real time, using OpenGL 3.3.
• NoiseTester is a rough visualization tool that shows how the output of different modules is combined.

There is a separate solution with the example applications in the Examples/ folder.

I think SharpNoise is in a pretty OK state and am not doing a lot of work on it any more. However, I would like to fix any bugs or other issues that crop up. So if anything's not right, please let me know.
