Set of transformation persistent OpenGl_Structure for building BVH tree. Provides built-in mechanism to invalidate tree when world view projection state changes. Due to frequent invalidation of BVH tree the choice of BVH tree builder is made in favor of BVH linear builder (quick rebuild). More...

Constructor & Destructor Documentation

OpenGl_BVHClipPrimitiveTrsfPersSet::OpenGl_BVHClipPrimitiveTrsfPersSet ( )

Creates an empty primitive set for BVH clipping.

Member Function Documentation

Standard_Boolean OpenGl_BVHClipPrimitiveTrsfPersSet::Add ( const OpenGl_Structure * theStruct )

Adds structure to the set.

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

virtual Graphic3d_BndBox3d OpenGl_BVHClipPrimitiveTrsfPersSet::Box ( const Standard_Integer theIdx ) const

overridevirtual

Returns AABB of the structure.

Implements BVH_Set< Standard_Real, 3 >.

const NCollection_Handle<BVH_Tree<Standard_Real, 3> >& OpenGl_BVHClipPrimitiveTrsfPersSet::BVH	(	const Handle< Graphic3d_Camera > &	theCamera,
		const OpenGl_Mat4d &	theProjectionMatrix,
		const OpenGl_Mat4d &	theWorldViewMatrix,
		const Standard_Integer	theViewportWidth,
		const Standard_Integer	theViewportHeight,
		const Graphic3d_WorldViewProjState &	theWVPState
	)

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

virtual Standard_Real OpenGl_BVHClipPrimitiveTrsfPersSet::Center	(	const Standard_Integer	theIdx,
		const Standard_Integer	theAxis
	)		const

overridevirtual

Calculates center of the AABB along given axis.

Implements BVH_Set< Standard_Real, 3 >.

void OpenGl_BVHClipPrimitiveTrsfPersSet::Clear ( )

Cleans the whole primitive set.

const OpenGl_Structure* OpenGl_BVHClipPrimitiveTrsfPersSet::GetStructureById ( Standard_Integer theId )

Returns the structure corresponding to the given ID.

void OpenGl_BVHClipPrimitiveTrsfPersSet::MarkDirty ( )

inline

Marks object state as outdated (needs BVH rebuilding).

Standard_Boolean OpenGl_BVHClipPrimitiveTrsfPersSet::Remove ( const OpenGl_Structure * theStruct )

Removes the given structure from the set.

Returns: true if structure removed, otherwise returns false (structure is not in the set).

virtual Standard_Integer OpenGl_BVHClipPrimitiveTrsfPersSet::Size ( ) const

overridevirtual

Returns total number of structures.

Implements BVH_Set< Standard_Real, 3 >.

virtual void OpenGl_BVHClipPrimitiveTrsfPersSet::Swap	(	const Standard_Integer	theIdx1,
		const Standard_Integer	theIdx2
	)

overridevirtual

Swaps structures with the given indices.

Implements BVH_Set< Standard_Real, 3 >.
