Coll simulation! I'm looking for any pointers to noise or other generative methods which looks like eroded terrain from the get-go, without the cost of simulating the erosion process. Any tips appreciated.

There are tricks to do it, I described some at the end of this blog post: https://jobtalle.com/layered_voxel_rendering.html

- If you raise all height values to a power, you get creases in the terrain that are generated by erosion in real life.

- If you raise all terrain values under a height just above sea level to a power, then you get beach like erosion, so flat areas will form along the shore.

I'll admit it, you made me look up "Coll simulation" to figure out what it was. Even though I assumed it was a typo. Which it is.
