Drawing a Spherical Mesh

[jgreenb2]

Han,

Thanks. I've actually done most of those things. I'll try some of your other suggestions. However, the drawing isn't the issue (it may not be right) -- the recursion itself seems to get lost after a short while and the program hangs. Given the limited debugging environment on the Prime, I haven't been able to make much more progress.

The real questions are these:

• Is there a known problem handling deep recursion on the Prime?
• What's the best way to implement something like a sphereical mesh?
  

Simple tail recursion -- like a factorial -- appear to work without issue. But when div is large the Prime stack appears to lose its place and drawSphere won't terminate.
