// 1. The rectangles represent the BSP planes of the BSP tree. They
// share a VertexColor3Effect. You can see a plane from either side
// (backface culling disabled). The planes do not interfere with view
// of the solid objects (wirestate enabled).
//
// 2. The sphere, tetrahedron, and cube share a TextureEffect. These
// objects are convex. The backfacing triangles are discarded
// (backface culling enabled). The front facing triangles are drawn
// correctly by convexity, so depthbuffer reads are disabled and
// depthbuffer writes are enabled. The BSP-based sorting of objects
// guarantees that front faces of convex objects in the foreground
// are drawn after the front faces of convex objects in the background,
// which allows us to set the depthbuffer state as we have. That is,
// BSPNode sorts from back to front.
//
// 3. The torus has backface culling enabled and depth buffering enabled.
// This is necessary, because the torus is not convex.
//
// 4. Generally, if all objects are opaque, then you want to draw from
// front to back with depth buffering fully enabled. You need to
// reverse-order the elements of the visible set before drawing. If
// any of the objects are semitransparent, then drawing back to front
// is the correct order to handle transparency. However, you do not
// get the benefit of early z-rejection for opaque objects. A better
// BSP sorter needs to be built to produce a visible set with opaque
// objects listed first (front-to-back order) and semitransparent
// objects listed last (back-to-front order).
