PTG - A minimal procedural generation library

This project provides utilities for the generation of random terrains. It includes:

• A collection of noise generators in 2D and 3D
  • Perlin noise
  • Simplex noise
  • OpenSimplex noise
  • Fractal variants of both Perlin and OpenSimplex noise
  • Simple value-based noises
• Region generators in 2D: they generate random shapes for biomes and other region-specific values, based on the legacy layered biome generator system of Minecraft (before 1.18).
• High performance!

Install using Gradle

For installing via Gradle, you need to add my Maven repository to your repositories.

repositories {
    mavenCentral()
    maven {
        url "https://maven.shadew.net/"
    }
}

dependencies {
    compile 'dev.runefox:ptg:3.0'
}

The latest version depends on the Fastutil library, version 8.2.1. This dependency is automatically included with the PTG library, but this requires that the Maven Central Repository is declared as a repository in your buildscript.

Experimental features

There are several experimental features implemented. These features may not work as expected or may be slow. Use cautiously. Such features are:

• Voronoi, Worley and Cell noise (all based on Voronoi); these can be excessively slow especially in higher dimensions.
• Repetitive noise; seamlessly repeating noise, but can look odd and is not available for Simplex and OpenSimplex noise.

Changelog

3.0

• Group ID and root package name are now dev.runefox instead of net.shadew.
