/**
* @class vtkEdgePoints
* @brief generate points on isosurface
*
* vtkEdgePoints is a filter that takes as input any dataset and
* generates for output a set of points that lie on an isosurface. The
* points are created by interpolation along cells edges whose end-points are
* below and above the contour value.
* @warning
* vtkEdgePoints can be considered a "poor man's" dividing cubes algorithm
* (see vtkDividingCubes). Points are generated only on the edges of cells,
* not in the interior, and at lower density than dividing cubes. However, it
* is more general than dividing cubes since it treats any type of dataset.
