vtkElevationFilter - generate scalars along a specified direction
Super Class: vtkDataSetToDataSetFilter
vtkElevationFilter 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.
Detailed Method Descriptions:
Construct object with LowPoint=(0,0,0) and HighPoint=(0,0,1). Scalar range is (0,1).
Define one end of the line (small scalar values).
Define other end of the line (large scalar values).
Specify range to map scalars into.
