Detailed Description

+The clip traversal. +

+The purpose of this traversal is to insert in the RenderTraversal the observers which are said to be not clipped. Some observers may do something else. +

+Observer should use the IBaseHrcObs->clip() method to implement their observer, or completly redefine the traverse() method. +

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

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

+This method must create a default observer for this traversal. +

+Any model which doesn't provide (by registerObs() or by inheritance) an observer for this view will be linked with this default observer. +
