I noticed that D was missing a flexible functional multi use noise library for game development. I fixed this by translating Auburn's Fast Noise - Lite into D as it's a header only implementation of multiple noise algorithms. These include:
- 2D & 3D
- OpenSimplex2 Noise
- OpenSimplex2S Noise
- Cellular (Voronoi) Noise
- Perlin Noise
- Value Noise
- Value Cubic Noise
- OpenSimplex2-based Domain Warp
- Basic Grid Gradient Domain Warp
- Multiple fractal options for all of the above
- Supports floats and/or doubles
The default is double.
You can see/get it here: https://code.dlang.org/packages/fast_noise
Here is an example on how to use it:
import std.stdio;
import std.random;
import fast_noise;
void main() {
// This is an example on how to use the library
FNLState noise = fnlCreateState();
noise.seed = unpredictableSeed();
noise.noise_type = FNLNoiseType.FNL_NOISE_PERLIN;
writeln("Begin perlin noise:");
for (double i = 0; i < 100; i++) {
double test = fnlGetNoise3D(&noise, 0,i,0);
writeln("noise: ", test);
}
// You can also initialize it with a seed
FNLState moreNoise = fnlCreateState(unpredictableSeed());
moreNoise.noise_type = FNLNoiseType.FNL_NOISE_OPENSIMPLEX2;
writeln("Begin OpenSimplex2 noise:");
for (double i = 0; i < 100; i++) {
double test = fnlGetNoise3D(&moreNoise, 0,i,0);
writeln("noise: ", test);
}
}```
Hopefully this small library gets you going on your noise generated implementation for your video game. Thanks for reading.
