// .NAME vtkCutMaterial - Automatically computes the cut plane for a material array pair.
|
|
// .SECTION Description
|
|
// vtkCutMaterial computes a cut plane based on an up vector, center of the bounding box
|
|
// and the location of the maximum variable value.
|
|
// These computed values are available so that they can be used to set the camera
|
|
// for the best view of the plane.
