Noise/Fractal heightmap

Troubleshooting SDK
1

Are there any classes letting you make fractal TerrainQuad?

I have found FractalTileLoader but its for TerrainGrid only from what I understand.

There are also these nice PerturbFilter, OptimizedErode, etc, but how do I use them with TerrainQuad if it asks for heightmap?

You can use the FractalSum class to generate noise.

Then you can create a BufferedImage from the result and save it on disk.

Or you can use this constructor for example:
[java]TerrainQuad(String name, int patchSize, int totalSize, float[] heightMap)[/java]

And insert your values there.
