We've seen a lot in this chapter. We've introduced a couple of advanced geometries and even showed you how you can create interesting looking geometries using a couple of simple binary operations. The most important things to remember from this chapter are these:
LatheGeometry. Once again, experiment with these geometries.
ExtrudeGeometryyou can easily create 3D geometries from 2D shapes. Normally this is done by extruding along the z-axis, but you can also extrude along a custom path.
