Is it possible to analyse slopes in a more advanced way than just their slope or elevation?
Ideally I want to be able to automatically find bits that aren't rough and roughen them up, and only those areas.
I know there are ways of generating terrain with erosion mattes and so on, but let's say I've already done that and want to find remaining areas of smoothness. I guess that's what I'm after - a smoothness analyser.
Another thing I'd like to be able to do is to apply shaders based on their slope in x,y, or z directions rather than all directions.
