GEO.LSP is a collection of functions that will generate an nthorder geodesic sphere of unit radius centered at the origin (0 0 0),
using AutoCAD 2.6 threedimensional faces. A 0thorder geodesic sphere is an icosahedron, having twenty triangular faces.
Each increment in order increases the number of faces by a factor of four; thus, a 1storder sphere has 80 faces, a 2ndorder
has 320 faces, etc. Be forwarned that the execution time for generating the spheres increases by factors of four as well!
The calling sequence for invoking the function is simply (geo n), where n is the desired order. After generation, the sphere may
be viewed from different directions using the VPOINT command, and hiddenface removal may be accomplished with the
HIDE command. Note that the time required for hidden face removal increases roughly as the square of the number of faces.
