DESCRIPTION
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.
SUMMARY
void SetLowPoint(float, float, float)
void SetLowPoint(float *)
Define one end of the line (small scalar values).
void SetHighPoint(float, float, float)
void SetHighPoint(float *)
Define other end of the line (large scalar values).
void SetScalarRange(float, float)
void SetScalarRange(float *)
Specify range to map scalars into.
vtkElevationFilter()
Construct object with LowPoint=(0,0,0) and HighPoint=(0,0,1). Scalar range is (0,1).
