# MatheusDev's Utils

## What is this?

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

## What does it have?

Currently, the following stuff is implemented:

* ["Matrix" -> Array mapping][MatrixMapping] for N dimensions.

* Optimized [2D][Matrix2Mapping] and [3D][Matrix3Mapping] versions of the above.

* A "[javatemplater][Templater.java]", which was used to create the Matrix->Array Mapping classes.

* [1D Simplex Noise][SimplexNoise.java].

* [Simplex Noise for N Dimensions][SimplexNoiseN.java].

* [2D][Noise2] and [3D][Noise3] optimized versions of the SimplexNoiseN algorithm.

* [1D Value Noise][ValueNoise1D.java].

* Helper for writing [Gif-Animations][GifSequenceWriter.java] to files.

* Lots of [Vector math utilities][Vecmath] for multiplying matrices, vectors, etc.

* A [collision detection framework][Collision] using the Seperating Axis Theorem (SAT) and rotateable Quads and Polygons.

* A bunch of other Utilities, like [FrameUtils][FrameUtils.java], for positioning java.awt.Frame's in the mid of a desired screen, [GriddedImage][GriddedImage.java] to create png-Image grids for SpriteSheets, [NumUtils][NumUtils.java] and a [TextFileReader][TextFileReader.java].

## What can I do with this?

Look at this:




![Demo GIF][SimplexNoiseDemoImg]

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

```java

MatrixNf values = new SimplexNoiseN(

        5,                                   // Octaves

        new Random(),                        // Random number generator RNG

        new FloatInterpolationCubicSpline(), // Value interpolator

        64, 256, 256                         // Dimensions (3D)

        ).get();

```
