Building shapes out of points, lines, and faces
Using shape control
- A solid shape is one where the insides are never seen
- If never seen, don't attempt to draw them
- When solid TRUE, the
back sides (inside) of faces are not drawn
- The front of a face has coordinates in counter-clockwise
order
- When ccw FALSE, the
other side is the front
- Faces are assumed to be convex
- When convex FALSE,
concave faces are automatically broken into multiple convex faces
