A basic method in MegaPOV would be to get a grid of height values (using trace)
and start comparing: if a point is higher than all 8 points around it (or 5
points at the edges, or 3 points in the corner) it is the top of a bump.
Of course it's a bit more complicated if you want more control, e.g. only
consider convexities above a certain scale as "bumps".
