Virtual from TAttBBox; fill bounding-box information.

The bounding-box information is kept coherent during addition of projected elements and projection parameter updates. This is called only in case the manager has not been populated at all.

Implements TAttBBox.

REveElement * REveProjectionManager::ImportElements	(	REveElement *	el,
		REveElement *	ext_list = `nullptr`
	)

virtual

Recursively import elements and apply projection to the newly imported objects.

If ext_list is not 0 the new element is also added to the list. This simplifies construction of complex views where projected elements are distributed into several scenes for optimization of updates and rendering.

Returns the projected replica of el. Can be 0, if el and none of its children are projectable.

	)

virtual

If el is REveProjectable add projected instance else add plain REveElementList to parent.

Call the same function on el's children.

Returns the projected replica of el. Can be 0, if el and none of its children are projectable.

Set projection type and distortion.

Definition at line 93 of file REveProjectionManager.cxx.

◆ ShouldImport()

Bool_t REveProjectionManager::ShouldImport ( REveElement * el )

protectedvirtual

Returns true if element el should be imported.

Behaviour depends on the value of the fImportEmpty member: false - el or any of its children must be projectable (default); true - always import.

◆ SubImportChildren()

Int_t REveProjectionManager::SubImportChildren	(	REveElement *	el,
		REveElement *	proj_parent
	)

virtual

Recursively import children elements of el and apply projection to the newly imported objects.

The proj_parent argument should be a projected replica of element 'el'. This allows to insert projected children of a given element when they are added after the projection has been already performed on the parent. This is called from REveElement::ProjectChild().

Returns the projected replica of el. Can be 0, if el and none of its children are projectable.

Definition at line 317 of file REveProjectionManager.cxx.

◆ SubImportElements()

REveElement * REveProjectionManager::SubImportElements	(	REveElement *	el,
		REveElement *	proj_parent
	)

virtual

Recursively import elements and apply projection to the newly imported objects.

The proj_parent argument should be a projected replica of parent of element 'el'. This allows to insert projected children of a given element when they are added after the projection has been already performed on the parent. This is called from REveElement::ProjectChild().

Returns the projected replica of el. Can be 0, if el and none of its children are projectable.
