Description

Heightmaps generator on PHP using perlin-noise algorithm.

This package is just an upgrade of https://github.com/A1essandro/perlin-noise-generator to support higher PHP version.
In the future it might contain decoupled function

Requirements

This package is only supported on PHP 8.4 and above.

Installing

Composer

See more getcomposer.org.

Execute command

composer require cryde/noise-functions

Usage

$generator = new MapGenerator\PerlinNoiseGenerator();
$generator->size = 100; //heightmap size: 100x100
$generator->persistence = 0.8; //map roughness
$generator->setMapSeed('value'); //optional
$map = $generator->generate();

or

$generator = new MapGenerator\PerlinNoiseGenerator();
$map = $generator->generate([
    PerlinNoiseGenerator::SIZE => 100,
    PerlinNoiseGenerator::PERSISTENCE => 0.8,
    PerlinNoiseGenerator::MAP_SEED => 'value'
]);

mixed:

$generator = new MapGenerator\PerlinNoiseGenerator();
$generator->size = 100;
$map = $generator->generate([
    PerlinNoiseGenerator::PERSISTENCE => 0.8
]);
