Public Member Functions
virtual void	push (SoState *state)
	Overrides push() method to copy values from next instance in the stack.

Public Member Functions inherited from SoModelMatrixElement
virtual void	print (FILE *fp) const
	Prints element (for debugging).

Public Member Functions inherited from SoElement
virtual void	pop (SoState state, const SoElement prevTopElement)
	Pops element.

virtual SoType	getTypeId () const
	Returns type identifier for element instance.

Public Member Functions inherited from SoTypedObject
SbBool	isOfType (const SoType &type) const
	Returns TRUE if this object is of the type specified in type or is derived from that type.

template<typename TypedObjectClass >
SbBool	isOfType () const
	Returns TRUE if this object is of the type of class TypedObjectClass or is derived from that class.

Static Public Member Functions
static SoType	getClassTypeId ()
	Returns the type identifier for this class.

static int	getClassStackIndex ()
	Returns the stack id for this element.

static void	reset (SoState state, SoNode node)
	Allows the SoGetBoundingBoxAction to reset the current model matrix to identity and all currently-open local matrices to identity.

static void	pushMatrix (SoState *state, SbMatrix &matrix, SbMatrix &localmatrix)
	Because two model matrices are kept track of during the getBoundingBoxAction (the local model matrix, used by separators to calculate their bbox caches, and the real model matrix), replacement routines for pushMatrix/popMatrix must be given; SoTransformSeparator::getBoundingBox uses these methods to correctly keep both matrices up-to-date.

static void	popMatrix (SoState *state, const SbMatrix &matrix, const SbMatrix &localmatrix)
	See description for pushMatrix().

Detailed Description

Stores the current model matrix for use with the SoGetBoundingBoxAction.

This element stores the current model matrix for use with the SoGetBoundingBoxAction. Overrides the virtual methods on SoModelMatrixElement to also set the current SoLocalBBoxMatrixElement.

This class relies on SoModelMatrixElement to store the matrix in the instance, and inherits most of its methods from it.

Member Function Documentation

◆ getClassStackIndex()

static int SoBBoxModelMatrixElement::getClassStackIndex ( )

static

Returns the stack id for this element.

◆ getClassTypeId()

static SoType SoBBoxModelMatrixElement::getClassTypeId ( )

static

Returns the type identifier for this class.

◆ popMatrix()

static void SoBBoxModelMatrixElement::popMatrix	(	SoState *	state,
		const SbMatrix &	matrix,
		const SbMatrix &	localmatrix
	)

static

See description for pushMatrix().

◆ push()

virtual void SoBBoxModelMatrixElement::push ( SoState * state )

virtual

Overrides push() method to copy values from next instance in the stack.

Reimplemented from SoModelMatrixElement.

◆ pushMatrix()

static void SoBBoxModelMatrixElement::pushMatrix	(	SoState *	state,
		SbMatrix &	matrix,
		SbMatrix &	localmatrix
	)

static

Because two model matrices are kept track of during the getBoundingBoxAction (the local model matrix, used by separators to calculate their bbox caches, and the real model matrix), replacement routines for pushMatrix/popMatrix must be given; SoTransformSeparator::getBoundingBox uses these methods to correctly keep both matrices up-to-date.

◆ reset()

static void SoBBoxModelMatrixElement::reset	(	SoState *	state,
		SoNode *	node
	)

static

Allows the SoGetBoundingBoxAction to reset the current model matrix to identity and all currently-open local matrices to identity.
