This function must be used between <b>beginShape()</b> and <b>endShape()</b> and only when there is no MODE parameter specified to <b>beginShape()</b>. <span class="warning">Using the 3D version of requires rendering with P3D or OPENGL (see the Environment reference for more information).</span></td>
