vtkStreamingDemandDrivenPipeline Class Reference
#include <vtkStreamingDemandDrivenPipeline.h>
Detailed Description
Executive supporting partial updates.vtkStreamingDemandDrivenPipeline is an executive that supports updating only a portion of the data set in the pipeline. This is the style of pipeline update that is provided by the old-style VTK 4.x pipeline. Instead of always updating an entire data set, this executive supports asking for pieces or sub-extents.
