Hello,

The problem with degenerated triangles in meshes is fixed (if you are in 
a hurry with this one I can send it to you).
Could you give more information about hollow dome (meshes are hollow) 
The other problem of evenly spaced meridians is a bit more tricky (at 
least for certain slopes), I hope I'll find some time this week to have 
a look on it.

  Hello:

    I love this plugin, but I am having a few problems with it.

    The meshs generated seem to be somewhat degenerate.  I tried a 
simple tetrahedron (3 sided circle with 1 parallel).  The mesh I got 
was:

  #declare Dome2 = mesh {
  triangle { <0.000000, 0.000000, 1.000000>, <0.000000, 0.000000, 
1.000000>, <-0.500000, 0.866025, -0.000000> }
  triangle { <-0.500000, 0.866025, -0.000000>, <1.000000, 0.000000, 
-0.000000>, <0.000000, 0.000000, 1.000000> }
  triangle { <0.000000, 0.000000, 1.000000>, <0.000000, 0.000000, 
1.000000>, <-0.500000, -0.866025, -0.000000> }
  triangle { <-0.500000, -0.866025, -0.000000>, <-0.500000, 0.866025, 
-0.000000>, <0.000000, 0.000000, 1.000000> }
  triangle { <0.000000, 0.000000, 1.000000>, <0.000000, 0.000000, 
1.000000>, <1.000000, 0.000000, -0.000000> }
  triangle { <1.000000, 0.000000, -0.000000>, <-0.500000, -0.866025, 
-0.000000>, <0.000000, 0.000000, 1.000000> }
  // Attributes returned success!

  Note that several of the triangles have the same exact first and 
second coordinates (marked in bold if you are viewing HTML).

  The problem I am having with this, is that I am attempting to make a 
'hollow' dome.  I was going to simply subtract one dome from another 
(CSG) but the results are weird.  If I delete the 0 width triangles, 
then it seems to work a little better, but I am left with only 3.

  Is there any chance this can be fixed?

  Also, as I'm trying to make a 'city dome' out of this, the parallels 
get spaced much too closly at the top of the dome.  Would there be any 
way to use the distance 'up' the parallels to space them out?

          == John ==

  P.S.  I could help with the plugin if it's C++
