Help with noise generators

[NotStirred]

In net.minecraft.world.gen, is NoiseGeneratorOctaves, which has a function generateNoiseOctaves

Where can I find infomation on the return value of this and other noise generators? It returns an array of size 825 which is of some significance I assume.

I have figured it out through some documentation on forge/other

Just curious if you'd mind sharing what you figured out? Messing with the noise generators is on my todo list

Sure!

 

I hadn't really looked into the generateNoiseOctaves function properly, it takes arguments:

(double[] noiseArray, int xOffset, int yOffset, int zOffset, int xSize, int ySize, int zSize, double xScale, double yScale, double zScale)

 

The return value shape is determined by the x-y-zSize parameters. These are the size of the region you want to sample. Changing the size will not change the scaling or the density of the noise, it sort of just expands the area generating new noise in those new parts.

The x-y-zScale parameters will of course change the scale.

The x-y-zOffset will move the noise around inside the area.

 

I then sampled points around this area with some interpolation to create the final world shape.
