Going to the trouble of cameras, lights, materials, and mesh geometries is a lot of work for an unimpressive triangle. However, you've now seen the bare bones of WPF's 3-D support. In this section, you'll learn how to use it to introduce more complex shapes.
Once you've mastered the lowly triangle, the next step up is to create a solid, faceted shape by assembling a small group of triangles. In the following example, you'll create the markup for the cube shown in Figure 23-8.
You'll notice that the edges of the cube in Figure 23-8 have smooth, anti-aliased edges. Unfortunately, if you're rendering 3-D on Windows ...
