It looks good. I would recommend two things. This is general advice, not
something that must be changed on this part (although it would improve the
pattern further):
1. When connecting quads/triangles/lines to primitives, use the same number
of decimal places as the primitives. Or more. All the disc, circle,
cylinder, cone, and ring primitives currently have 4 decimal places.
2. Use common vertices for quads, triangles, and area-filling primitives.
Whenever a renderer works on a scene, it takes the data from the DAT files,
and transforms them to form the correct presentation. This means the
numbers get modified, and small rounding errors can result when points are
mapped to pixels. Usually, this is no big deal. But it can cause points
that *should* be in a straight line to fall out of alignment. If the
graphics primitives are tied together by common corners (wherever
possible), the misalignment effect will be greatly reduced.
