52 //! OpenGL Point Sprites PolyData Mapper.
54 * VTKViewer_PolyDataMapper is a class that maps polygonal data
55 * (i.e., vtkPolyData) to graphics primitives. It is performing the mapping
56 * to the rendering/graphics hardware/software. It is now possible to set a
57 * memory limit for the pipeline in the mapper. If the total estimated memory
58 * usage of the pipeline is larger than this limit, the mapper will divide
59 * the data into pieces and render each in a for loop.
