bool GU_ConvexHullHalfPlanesT< T >::findActivePlanes	(	UT_Array< IDX > &	activeplanes,

		T	rad
	)		const

inline

Constructs a list of planes that are active for the given sphere. These will be any planes that intersect the sphere. The idea being that if one has already culled by this sphere, only these planes have to be tested to if we are in or out. If no active planes are found, the return result will be true if entirely inside the planes, or false if entirely out.
