name="_details"></a><h2>Detailed Description</h2> +The Render traversal. +<p> +The purpose of this traversal is to render a list of models. This traversals is tightly linked to the cliptraversal. The clipTraversals insert directly the observers with CRenderTrav::addRenderObs(obs). The <a class="el" href="class_NL3D__CRenderTrav.html#a4">traverse</a>() method should render all the render observer with <a class="el" href="class_NL3D__IDriver.html">IDriver</a>. +<p> +This traversal is an exception since it is not designed to have a graph of observers. But this behavior is permitted, and the root (if any) is traversed. +<p> +<b>USER</b> <b>RULES</b>: Before using <a class="el" href="class_NL3D__CRenderTrav.html#a4">traverse</a>() on a render
