Detailed Description

synchronizes renderers across processes.

vtkSynchronizedRenderers is used to synchronize renderers (vtkRenderer and subclasses) across processes for parallel rendering. It's designed to be used in conjunction with vtkSynchronizedRenderWindows to synchronize the render windows among those processes. This class handles synchronization of certain render parameters among the renderers such as viewport, camera parameters. It doesn't support compositing of rendered images across processes on its own. You typically either subclass to implement a compositing algorithm or use a renderer capable of compositing eg. IceT based renderer.

virtual void vtkSynchronizedRenderers::SetRootProcessId ( int )

virtual

Get/Set the root-process id.

This is required when the ParallelController is a vtkSocketController. Set to 0 by default (which will not work when using a vtkSocketController but will work for vtkMPIController).

virtual int vtkSynchronizedRenderers::GetRootProcessId ( )

virtual

Get/Set the root-process id.
