Due to frequent invalidation of BVH tree the choice of BVH tree builder is made in favor of BVH linear builder (quick rebuild). More...

Returns: true if structure added, otherwise returns false (structure already in the set).

virtual Select3D_BndBox3d SelectMgr_SelectableObjectTrsfPersSet::Box ( const Standard_Integer theIndex ) const

overridevirtual

Returns bounding box of object with index theIndex.

Implements BVH_Set< Standard_Real, 3 >.

		const Graphic3d_Mat4d &	theWorldViewMatrix,
		const Graphic3d_WorldViewProjState &	theWVPState
	)

Returns BVH tree for the given world view projection (builds it if necessary).

virtual Standard_Real SelectMgr_SelectableObjectTrsfPersSet::Center	(	const Standard_Integer	theIndex,
