// .NAME vtkPolyDataMapper - map vtkPolyData to graphics primitives
|
||
|
|
// .SECTION Description
|
||
|
|
// vtkPolyDataMapper is a class that maps polygonal data (i.e., vtkPolyData)
|
||
|
|
// to graphics primitives. vtkPolyDataMapper serves as a superclass for
|
||
|
|
// device-specific poly data mappers, that actually do 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.
