/**
* @class vtkVolumeOfRevolutionFilter
* @brief sweep data about a line to create a volume
*
* vtkVolumeOfRevolutionFilter is a modeling filter. It takes a 2-dimensional
* dataset as input and generates an unstructured grid on output. The input
* dataset is swept around the axis of rotation to create dimension-elevated
* primitives. For example, sweeping a vertex creates a series of lines;
* sweeping a line creates a series of quads, etc.
*
* @warning
* The user must take care to ensure that the axis of revolution does not cross
* through the geometry, otherwise there will be intersecting cells in the
* output.
