I think I tried almost anything using modifiers like splitting a plane into quads with split edge and then adding a fat solidify modifier and after that a displace modifier, but the problem I keep running into is that you can’t use the displace modifier per face. It’s only per vertex. I also tried a particle emitter with long cubes, but I didn’t see any options of changing the height of the particles using a texture or anything similar to that.
So do any of you guys have any ideas about how to do something like this?

EDIT: Alright, so I was able to get the pretty much same result. What I would like to do now is do the same thing using a Sphere. Is there any way to displace whole faces instead of vertices?
