Hi, Does anyone have a reliable written guide to the terminology of the transformation functions in math.c, and the geometrical model(s) they assume? Almost every time I try to work out the geometry behind one of these functions I end up puzzled and brainfatigued. I'm particularly interested in the mappings that explicitly involve spherical coordinates. Thanks, Tom
