Detailed Description

OpenGL Point Sprites PolyData Mapper.

VTKViewer_PolyDataMapper is a class that maps polygonal data (i.e., vtkPolyData) to graphics primitives. It is performing the mapping to the rendering/graphics hardware/software. It is now possible to set a memory limit for the pipeline in the mapper. If the total estimated memory usage of the pipeline is larger than this limit, the mapper will divide the data into pieces and render each in a for loop.
