Detailed Description

Returns the portion of the input dataset that lies within a selection frustum.

This class intersects the input DataSet with a frustum and determines which cells and points lie within the frustum. The frustum is defined with a vtkPlanes containing six cutting planes. The output is a DataSet that is either a shallow copy of the input dataset with two new "vtkInsidedness" attribute arrays, or a completely new UnstructuredGrid that contains only the cells and points of the input that are inside the frustum. The PreserveTopology flag controls which occurs. When PreserveTopology is off this filter adds a scalar array called vtkOriginalCellIds that says what input cell produced each output cell. This is an example of a Pedigree ID which helps to trace back results.
