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.
Query ranges of scalar values of objects in addition to the boundry in three-space

Events:: vtkCommand::StartEvent vtkCommand::EndEvent

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]

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

virtual vtkMultiProcessController* vtkParallelRenderManager::GetController ( ) [virtual]

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

virtual void vtkParallelRenderManager::ComputeVisiblePropBounds ( vtkRenderer * ren,

double bounds[6]

) [virtual]

Calculates the bounds by gathering information from all processes.

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::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).
