Reimplemented from vtkSource . This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Gradient computation is fairly expensive in both time and storage. Note that if ComputeNormals is on, gradients will have to be calculated, but will not be stored in the output dataset. If the output data will be processed by filters that modify topology or geometry, it may be wise to turn Normals and Gradients off.

Set the number of contours to place into the list. You only really need to use this method to reduce list size. Set a particular contour value at contour number i.
