Detailed Description

Scene graph operator that sorts a scene by render states.

Author:

Victor Saar The StateSortingOperator is a scene graph operator that sorts a scene by contained render states. Each render state to sort by requires a StateHandler. The operator'sconstructor takes an array of such state handlers. The order of state handlers defines the used sort priority. Each LODNode in the scene is optimized separately, as only a single sub-scene of a LODNode is rendered at a time. For convenience the operator defines typedefs for common state handlers. Importantto note is that the operator does not preserve transformations contained in the scene. Therefore the CollapseTransformsOperator should be applied on scenes with transformations (of course, this only helps with polygon sets).
