This is a collection of useful classes in java, without dependencies to outer libs, except the standard java lib.

Currently, the following stuff is implemented:

• "Matrix" -> Array mapping for N dimensions.
• Optimized 2D and 3D versions of the above.
• A "javatemplater", which was used to create the Matrix->Array Mapping classes.
• 1D Simplex Noise.
• Simplex Noise for N Dimensions.
• 2D and 3D optimized versions of the SimplexNoiseN algorithm.
• 1D Value Noise.
• Helper for writing Gif-Animations to files.
• Lots of Vector math utilities for multiplying matrices, vectors, etc.
• A collision detection framework using the Seperating Axis Theorem (SAT) and rotateable Quads and Polygons.
• A bunch of other Utilities, like FrameUtils, for positioning java.awt.Frame's in the mid of a desired screen, GriddedImage to create png-Image grids for SpriteSheets, NumUtils and a TextFileReader.

Look at this:

All the Noise values generated for this image are basically gotten from this code:

MatrixNf values = new SimplexNoiseN(
        5,                                   // Octaves
        new Random(),                        // Random number generator RNG
        new FloatInterpolationCubicSpline(), // Value interpolator
        64, 256, 256                         // Dimensions (3D)
        ).get();
