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. #ifndef __vtkElevationFilter_h #define __vtkElevationFilter_h #include "vtkDataSetAlgorithm.h" class VTK_GRAPHICS_EXPORT vtkElevationFilter : public vtkDataSetAlgorithm { public: static vtkElevationFilter* New(); vtkTypeRevisionMacro(vtkElevationFilter, vtkDataSetAlgorithm); void PrintSelf(ostream& os, vtkIndent indent); // Description: // Define one end of the line (small scalar values).
