  // .NAME vtkMyElevationFilter - generate scalars along a specified direction
  // .SECTION Description
  // vtkMyElevationFilter is a filter to generate scalar values from a
  // dataset.  The scalar values lie within a user specified range, and
  // are generated by computing a projection of each dataset point onto
  // a line. The line can be oriented arbitrarily. A typical example is
  // to generate scalars based on elevation or height above a plane.
