privatedelete

◆ REveProjectionManager() [2/2]

REveProjectionManager::REveProjectionManager ( REveProjection::EPType_e  type = REveProjection::kPT_Unknown)

Constructor.

Definition at line 39 of file REveProjectionManager.cxx.

◆ ~REveProjectionManager()

REveProjectionManager::~REveProjectionManager ( )
virtual

Destructor.

Destroys also dependent elements.

Definition at line 53 of file REveProjectionManager.cxx.

Member Function Documentation

◆ AddDependent()

void REveProjectionManager::AddDependent ( REveElement el)

Add el as dependent element.

Definition at line 66 of file REveProjectionManager.cxx.

◆ ComputeBBox()

void REveProjectionManager::ComputeBBox ( )
overridevirtual

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.

Definition at line 383 of file REveProjectionManager.cxx.

◆ GetCenter()

REveVector& ROOT::Experimental::REveProjectionManager::GetCenter ( )
inline

Definition at line 62 of file REveProjectionManager.hxx.

◆ GetCurrentDepth()

Float_t ROOT::Experimental::REveProjectionManager::GetCurrentDepth ( ) const

◆ GetProjection()

REveProjection* ROOT::Experimental::REveProjectionManager::GetProjection ( )
inline

Definition at line 57 of file REveProjectionManager.hxx.

◆ ImportElements()

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.

Definition at line 251 of file REveProjectionManager.cxx.

◆ ImportElementsRecurse()

REveElement * REveProjectionManager::ImportElementsRecurse ( REveElement el,
REveElement parent 
)
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.

Definition at line 197 of file REveProjectionManager.cxx.

◆ operator=()

REveProjectionManager& ROOT::Experimental::REveProjectionManager::operator= ( const REveProjectionManager )
privatedelete

◆ ProjectChildren()

void REveProjectionManager::ProjectChildren ( )
virtual

Project all children recursively, update bounding-box and notify EveManger about the scenes that have been changed.

Definition at line 362 of file REveProjectionManager.cxx.

◆ ProjectChildrenRecurse()

void REveProjectionManager::ProjectChildrenRecurse ( REveElement el)
virtual

Project el (via REveProjected::UpdateProjection()) and recurse through el's children.

Bounding-box is updated along the recursion.

Definition at line 339 of file REveProjectionManager.cxx.

◆ RemoveDependent()

void REveProjectionManager::RemoveDependent ( REveElement el)

Remove el as dependent element.

Definition at line 74 of file REveProjectionManager.cxx.

Float_t  y,
Float_t  z 
)

Set projection center and rebuild projected scene.

Definition at line 135 of file REveProjectionManager.cxx.

◆ SetCurrentDepth()

void ROOT::Experimental::REveProjectionManager::SetCurrentDepth ( Float_t  d)
inline

Definition at line 64 of file REveProjectionManager.hxx.

◆ SetImportEmpty()

void ROOT::Experimental::REveProjectionManager::SetImportEmpty ( Bool_t  ie)
inline

Definition at line 67 of file REveProjectionManager.hxx.

◆ SetProjection()

void REveProjectionManager::SetProjection ( REveProjection::EPType_e  type)

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.

Definition at line 149 of file REveProjectionManager.cxx.

◆ 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 312 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.

Definition at line 283 of file REveProjectionManager.cxx.

◆ UpdateDependentElsAndScenes()

void REveProjectionManager::UpdateDependentElsAndScenes ( REveElement root)

Update dependent elements' bounding box and mark scenes containing element root or its children as requiring a repaint.

◆ UpdateName()

void REveProjectionManager::UpdateName ( )
virtual

Updates name to have consistent information with projection.
