geometric objects. These routines reflect functionality available in the
<code>aux</code> toolkit described in the <em>OpenGL Programmer\'s Guide</em> and are included
in GLUT to allow the construction of simple GLUT programs that render
recognizable objects. These routines can be implemented as pure OpenGL
rendering routines. The routines do not generate display lists for the
objects they create. The routines generate normals appropriate for lighting
but do not generate texture coordinates (except for the teapot).
