This package implements several functions for three-dimensional graphics, which are especially useful in preparing graphics for the LiveGraphics3D applet. At some point, I should figure out why this is happening and actually fix it.
Several functions work only with flat, convex polygons.
However, PolygonTriangulation routines can be used to break up concave polygons. Several functions deal only with polygons while they should also deal with lines. The output file consists of a single long line with no newlines, and therefore is difficult to view in Mathematica and some text editors. Nothing has been seriously tested. This package is still under construction.
