This project features an animation of a 3D cube rotating using trigonometric functions. You can adapt the 3D point rotation math and the
line() function in your own animation programs.
Although the block text characters we’ll use to draw the cube don’t look like thin, straight lines, this kind of drawing is called a wireframe model because it renders only the edges of an object’s surfaces. Figure 62-1 shows the wireframe model for a cube and an icosphere, a rough sphere made of triangles.
