This class handles static optimization of an object. More...
This class handles static optimization of an object.
CSceneOptimizer handles optimization for a set of C3DExtObject objects. CSceneOptimizer::Optimize calls the C3DExtObject::Optimize for each objects it contains.
When optimizing an object there is two phases:
Calling C3DExtObject directly give you some additional possibilities compared to accessing them only through CSceneOptimizer.
