// .NAME vtkElevationFilter - generate scalars along a specified direction
|
||
|
|
// .SECTION 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.
