Using my lines, there is a problem with making the backfaces, if you know what I mean. They just don't line up properly. They go all wonky.
Twenty minutes later, I solved the problem with Displace. Go figger. The backfaces line up pretty **** good. Just a little refining and it's good to go. Although, there are two problems:
1) A little bit of math is required. Although, you could forego the math and do some hit-or-miss. Even with some math, some hit-or-miss will have to be done, but not as much w/out it.
2) It's set in stone, so to speak. At least theta is. Rho can be easily adjusted by rotating the D-Map, but the math or hit-or-miss will have to be done again.
Now that I think about it, I might be able to come up with a better variation. I'll have to do some serious fiddling. Great. Just great. I might have to put yet another Displace tutorial on-deck.
Back to the salt mine.
