    In a way isn't that what lathes, sors, and prisms do ?

    If that's not a satisfactory approach there is a great little
Dos utility called Geodome that creates shapes of the same
name.
    It offers some user options that allow you to control
the number of nodes, spherical or cylindrical shape, and
direction scaling.
    It's output spits out triangles and optionally cylinders, acting
as cross supports, and Pov spheres as node connection points.
    Geodome might do what you want. If not the triangles are
there and can be moved or removed as needed to get the shape
you want
    If you can't located geodome I think it's on the POV-Ray
ftp server. If not it's a small program which I have on CD
so I could send you a copy.

    I took the time once to hand code a sphere like object with
triangles and I definitely don't recommend others try this.
