Detailed Description

An object to control parallel rendering.

vtkParallelRenderManager operates in multiple processes. It provides proper renderers and render windows for performing the parallel rendering correctly. It can also attach itself to render windows and propagate rendering events and camera views.

Attention: Many parallel rendering schemes do not correctly handle transparency. Unless otherwise documented, assume a sub class does not.

Todo:: Synchronization/barrier primitives.

Todo:: Query ranges of scalar values of objects in addition to the boundary in three-space

static

◆ IsA()

virtual vtkTypeBool vtkParallelRenderManager::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

Reimplemented in vtkCompositeRenderManager, and vtkImageRenderManager.

◆ SafeDownCast()

static vtkParallelRenderManager * vtkParallelRenderManager::SafeDownCast ( vtkObjectBase * o )

◆ NewInstanceInternal()

virtual vtkObjectBase * vtkParallelRenderManager::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented in vtkCompositeRenderManager, and vtkImageRenderManager.

◆ NewInstance()

vtkParallelRenderManager * vtkParallelRenderManager::NewInstance ( ) const

◆ PrintSelf()

void vtkParallelRenderManager::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

◆ MakeRenderWindow()

virtual vtkRenderWindow * vtkParallelRenderManager::MakeRenderWindow ( )

virtual

Builds a vtkRenderWindow compatible with this render manager.

The user program is responsible for registering the render window with the SetRenderWindow method and calling Delete. It is not advisable to use a parallel render manager with a render window that was not built with this method.

◆ MakeRenderer()

virtual vtkRenderer * vtkParallelRenderManager::MakeRenderer ( )

virtual

Builds a vtkRenderer compatible with this render manager.

(Should we also register it?) The user program is responsible for calling Delete. It is not advisable to use a parallel render manager with a renderer that was not built with this method.

◆ GetRenderWindow()

virtual vtkRenderWindow * vtkParallelRenderManager::GetRenderWindow ( )

virtual

Set/Get the RenderWindow to use for compositing.

We add a start and end observer to the window.

◆ SetRenderWindow()

virtual void vtkParallelRenderManager::SetRenderWindow ( vtkRenderWindow * renWin )

virtual

Set/Get the RenderWindow to use for compositing.

We add a start and end observer to the window.

◆ GetController()

virtual vtkMultiProcessController * vtkParallelRenderManager::GetController ( )

virtual

Set/Get the vtkMultiProcessController which will handle communications for the parallel rendering.

◆ SetController()

virtual void vtkParallelRenderManager::SetController ( vtkMultiProcessController * controller )

virtual

Set/Get the vtkMultiProcessController which will handle communications for the parallel rendering.

◆ InitializePieces()

virtual void vtkParallelRenderManager::InitializePieces ( )

virtual

This method sets the piece and number of pieces for each actor with a polydata mapper.

◆ InitializeOffScreen()

virtual void vtkParallelRenderManager::InitializeOffScreen ( )

virtual

Make all rendering windows not viewable set as off screen rendering.

To make all renderwindows on screen rendering again, call OffScreenRenderingOff on all the render windows. This class assumes the window on root node is the only one viewable. Subclasses should change this as necessary.

◆ StartInteractor()

virtual void vtkParallelRenderManager::StartInteractor ( )

virtual

Initializes the RMIs and then, if on root node, starts the interactor on the attached render window.

Otherwise, starts processing RMIs. When the interactor returns, it breaks the RMI listening on all other processors.

◆ StartServices()
