Detailed Description

+The Render traversal. +

+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 traverse() method should render all the render observer with IDriver. +

+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. +

+USER RULES: Before using traverse() on a render traversal, you should:

+NB: see CScene for 3d conventions (orthonormal basis...) +
