/**
 * @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.
