I hope that somebody can help me with this. I need a mesh 2 sphere with a 1
unit diameter. I do not have any software to create this myself. I will use
the sphere to create a twisted rope. Lot's of rope means lots of memory, so
I figure a mesh 2 object will be the best way to go.
Thanks,
Tim

Look for HF_Sphere macro in shapes.inc, use flat heigfielt function to create
this sphere and redirrect its output to file as described in manual.

Thank you very much. I had no idea I had these objects available to me. This
is exactly what I was looking for.

It sounds like you want to make many copies of a mesh sphere. This will
not have any real benefit memory-wise, and will just be slower
rendering. You should just make the rope out of a mesh. Or make segments
of the rope out of meshes.
In any case, the height field macros don't give a very good
tessellation. A better one would be to tessellate the sides of a box,
and then normalize the points, giving you a unit-radius sphere. You
could also recursively subdivide a polyhedron, but that gives less
control over the number of triangles. Also, mesh2 will parse faster and
produce smaller mesh files, but will not render any differently from an
ordinary mesh. It is only an alternative syntax.
