virtual ElementIntersector* sofa::core::componentmodel::collision::Intersection::findIntersector	(	core::CollisionModel *	object1,
		core::CollisionModel *	object2,
		bool &	swapModels
	)			[pure virtual]

Return the intersector class handling the given pair of collision models, or NULL if not supported.

Parameters:

swapModel

output value set to true if the collision models must be swapped before calling the intersector.
