Detailed Description

sort poly data along camera view direction

vtkDepthSortPolyData rearranges the order of cells so that certain rendering operations (e.g., transparency or Painter's algorithms) generate correct results. To use this filter you must specify the direction vector along which to sort the cells. You can do this by specifying a camera and/or prop to define a view direction; or explicitly set a view direction.

Warning:

The sort operation will not work well for long, thin primitives, or cells that intersect, overlap, or interpenetrate each other.

Examples:

void vtkDepthSortPolyData::PrintSelf (  ostream &  os, vtkIndent  indent )  [virtual]

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkPolyDataAlgorithm.
