Detailed Description

vtkHardwareSelector useful for parallel rendering.

vtkPHardwareSelector is a vtkHardwareSelector that is parallel aware. It relies on the fact that the application is going to use some other mechanism to ensure that renders are synchronized among windows on all processes. The synchronization happens from the root node. When the root node renders, all processes render. Only vtkPHardwareSelector instance on the root node triggers the renders. All other processes, simply listen to the StartEvent fired and beginning of the render to ensure that vtkHardwareSelector's CurrentPass is updated appropriately.

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.

virtual

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 vtkOpenGLHardwareSelector.

virtual void vtkPHardwareSelector::SetProcessIsRoot ( bool  )

virtual

Set/Get the is the root process. The root processes is the only processes which has the composited result and hence the only processes that capture buffers and builds selected list ids.

Set/Get the is the root process. The root processes is the only processes which has the composited result and hence the only processes that capture buffers and builds selected list ids.

virtual void vtkPHardwareSelector::ProcessIsRootOn ( )

virtual

Set/Get the is the root process. The root processes is the only processes which has the composited result and hence the only processes that capture buffers and builds selected list ids.

virtual void vtkPHardwareSelector::ProcessIsRootOff ( )

virtual

Set/Get the is the root process. The root processes is the only processes which has the composited result and hence the only processes that capture buffers and builds selected list ids.

virtual bool vtkPHardwareSelector::CaptureBuffers ( )

virtual

Overridden to only allow the superclass implementation on the root node. On all other processes, the updating the internal state of the vtkHardwareSelector as the capturing of buffers progresses is done as a slave to the master render.
