<p>The other 2-D element we need is some way to erase the polygon at its old location before it&rsquo;s moved and redrawn. We&rsquo;ll do that by remembering the bounding rectangle of the polygon each time it&rsquo;s drawn, then erasing by clearing that area with a rectangle fill.</p>
<p>With the 2-D side of the picture well under control, we&rsquo;re ready to concentrate on the good stuff. Listings 50.2 through 50.5 are the sample 3-D animation program. Listing 50.2 provides matrix multiplication functions in a straightforward fashion. Listing 50.3 transforms, projects, and draws polygons. Listing 50.4 is the general header file for the program, and Listing 50.5 is the main animation program.</p>
