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
