// .NAME vtkSelectEnclosedPoints - mark points as to whether they are inside a closed surface
// .SECTION Description
// vtkSelectEnclosedPoints is a filter that evaluates all the input points to
// determine whether they are in an enclosed surface. The filter produces a
// (0,1) mask (in the form of a vtkDataArray) that indicates whether points 
// are outside (mask value=0) or inside (mask value=1) a provided surface.
// (The name of the output vtkDataArray is "SelectedPointsArray".)
//
// After running the filter, it is possible to query it as to whether a point 
// is inside/outside by invoking the IsInside(ptId) method.

// .SECTION Caveats
// The filter assumes that the surface is closed and manifold. A boolean flag
// can be set to force the filter to first check whether this is true. If false,
// all points will be marked outside. Note that if this check is not performed
// and the surface is not closed, the results are undefined.
//
// This filter produces and output data array, but does not modify the input 
// dataset. If you wish to extract cells or poinrs, various threshold filters
// are available (i.e., threshold the output array).

// .SECTION See Also
// vtkMaskPoints
