You can specify the number of levels of subdivision using <code><em><strong>depth</strong></em></code>. For example, a <code><strong><em>depth</em></strong></code> of 0 will draw an icosahedron. A <code><em><strong>depth</strong></em></code> of 1 will subdivide each triangle of the icosahedron into four triangles, for a total of 80 triangles.</P> 34<P>By default, this function generates both position and normal information in 32-bit floating point. The function saves the current vertex descriptor and the vertex attribute format used before drawing (and restores them afterward), so as not to interfere with the application's state. An example usage is:<br></P> 35<P><a href="GXDrawSphere.html">GXDrawSphere1</a>(2);</code><br></P> 36<P><br> The model is drawn centered about the origin.
