<p>Initial copy of section to be changed.</p>
<p><b>New page</b></p><div>* Additional uv mapping supported objects. <br />
<br />
==Supported Objects==<br />
<p>Surface mapping is currently defined for the following objects:</p><br />
<ul><br />
<li><strong>bicubic_patch</strong> : UV coordinates are based on the patch's parametric coordinates. They stretch with the control points. The default range is (0..1) and can be changed.</li><br />
<li><strong>box</strong> : the image is <em>wrapped</em> around the box, as shown below.</li><br />
<li><strong>lathe, sor</strong> : modified spherical mapping... the u coordinate (0..1) wraps around the y axis, while the v coordinate is linked to the object's control points (also ranging 0..1). Surface of Revolution also has special disc mapping on the end caps if the object is not 'open'.</li><br />
<li><strong>mesh, mesh2</strong> : UV coordinates are defined for each vertex and interpolated between.</li><br />
<li><strong>ovus</strong> : spherical mapping centered near the center of mass of the ovus (moving from one sphere to another as the ratio of radius progresses).</li><br />
<li><strong>parametric</strong> : In this case the map is not taken from a fixed set of coordinates but the map is taken from the area defined by the boundaries of the uv-space, in which the parametric surface has to be calculated.</li><br />
<li><strong>sphere</strong> : boring spherical mapping.</li><br />
<li><strong>torus</strong> : The map is taken from the area &lt;0,0&gt;&lt;1,1&gt; where the u-coordinate is wrapped around the major radius and the the v-coordinate is wrapped around the minor radius. </li><br />
</ul></div>
