Detailed Description

A GPU resident data set.

vtkPistonDataObject is a basic data structure for storing datasets on GPU. This class provides the infrastructure for the VTK pipeline to work with the data as it does the rest of the vtkDataObjects. The GPU side structures are managed through the internal vtkPistonReference instance to keep the GPU/CPU code conceptually distinct.
