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.

This class is based on the vtkCompositeManager class, except that it can handle any type of parallel rendering.

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 boundry in three-space

Events:

vtkCommand::StartEvent vtkCommand::EndEvent

virtual int vtkParallelRenderManager::IsA (  const char *  type  )  [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 vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkObject. Reimplemented in vtkCompositeRenderManager.

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. Reimplemented in vtkCompositeRenderManager.

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.

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.

virtual vtkRenderWindow* vtkParallelRenderManager::GetRenderWindow (   )  [virtual]

Set/Get the RenderWindow to use for compositing. We add a start and end observer to the window.

virtual void vtkParallelRenderManager::SetRenderWindow (  vtkRenderWindow *  renWin  )  [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.

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

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.

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.

virtual void vtkParallelRenderManager::StartServices (   )  [virtual]

If on node other than root, starts serving RMI requests for parallel renders.

virtual void vtkParallelRenderManager::StopServices (   )  [virtual]

If on root node, stops the RMI processing on all service nodes.

virtual void vtkParallelRenderManager::InitializeRMIs (   )  [virtual]

virtual void vtkParallelRenderManager::ResetAllCameras (   )  [virtual]

Resets the camera of each renderer contained in the RenderWindow. Should only be called in the "root" process, and all remote processes must be processing RMIs for this method to complete.

virtual void vtkParallelRenderManager::ComputeVisiblePropBounds (  vtkRenderer *  ren, double  bounds[6] )  [virtual]

Calculates the bounds by gathering information from all processes.

virtual void vtkParallelRenderManager::SetParallelRendering (  int   )  [virtual]

Calculates the bounds by gathering information from all processes.

virtual void vtkParallelRenderManager::ParallelRenderingOn (   )  [virtual]

Calculates the bounds by gathering information from all processes.

Calculates the bounds by gathering information from all processes.

virtual void vtkParallelRenderManager::SetRenderEventPropagation (  int   )  [virtual]

virtual int vtkParallelRenderManager::GetRenderEventPropagation (   )  [virtual]

Turns on/off render event propagation. When on (the default) and ParallelRendering is on, process 0 will send an RMI call to all remote processes to perform a synchronized render. When off, render must be manually called on each process.

virtual void vtkParallelRenderManager::RenderEventPropagationOn (   )  [virtual]

Turns on/off render event propagation. When on (the default) and ParallelRendering is on, process 0 will send an RMI call to all remote processes to perform a synchronized render. When off, render must be manually called on each process.

virtual void vtkParallelRenderManager::RenderEventPropagationOff (   )  [virtual]

Turns on/off render event propagation. When on (the default) and ParallelRendering is on, process 0 will send an RMI call to all remote processes to perform a synchronized render. When off, render must be manually called on each process.

virtual void vtkParallelRenderManager::SetUseCompositing (  int   )  [virtual]

This is used for tiled display rendering. When data has been duplicated on all processes, then we do not need to compositing. Cameras and renders are still propagated though.

virtual int vtkParallelRenderManager::GetUseCompositing (   )  [virtual]

This is used for tiled display rendering. When data has been duplicated on all processes, then we do not need to compositing. Cameras and renders are still propagated though.

virtual void vtkParallelRenderManager::UseCompositingOn (   )  [virtual]

virtual void vtkParallelRenderManager::SetImageReductionFactor (  double  factor  )  [virtual]

Set/Get the reduction factor (for sort-last based parallel renderers). The size of rendered image is divided by the reduction factor and then is blown up to the size of the current vtkRenderWindow. Setting higher reduction factors enables shorter image transfer times (which is often the bottleneck) but will greatly reduce image quality. A reduction factor of 2 or greater should only be used for intermediate images in interactive applications. A reduction factor of 1 (or less) will result in no change in image quality. A parallel render manager may ignore the image reduction factor if it will result in little or no performance enhancements (eg. it does not do image space manipulations).

virtual double vtkParallelRenderManager::GetImageReductionFactor (   )  [virtual]

Set/Get the reduction factor (for sort-last based parallel renderers). The size of rendered image is divided by the reduction factor and then is blown up to the size of the current vtkRenderWindow. Setting higher reduction factors enables shorter image transfer times (which is often the bottleneck) but will greatly reduce image quality. A reduction factor of 2 or greater should only be used for intermediate images in interactive applications. A reduction factor of 1 (or less) will result in no change in image quality.

virtual void vtkParallelRenderManager::SetWriteBackImages (  int   )  [virtual]

If on (the default), the result of any image space manipulations are written back to the render window frame buffer. If off, the image stored in the frame buffer may not be correct.

virtual int vtkParallelRenderManager::GetWriteBackImages (   )  [virtual]

If on (the default), the result of any image space manipulations are written back to the render window frame buffer. If off, the image stored in the frame buffer may not be correct.
