Stephen,
I experimented with a heightfield on a cylinder and a sphere with excellent
results, but what I'd really like to do is create a heightfield on a flat
surface, which can be converted to a mesh that can be manipulated in Moray.
I tried doing this with p_square.pov, but could not figure out the proper
coding. I need to have values for F1, F2, and F3, and I don't have a clue
what they should be. I tried different things and got some interesting
shapes, but nothing even in the same universe as what I was trying for. Do
you have any suggestions?
