// .NAME vtkVolumePicker - ray-cast picker enhanced for volumes
// .SECTION Description
// vtkVolumePicker is a subclass of vtkCellPicker. It has one
// advantage over vtkCellPicker for volumes: it will be able to
// correctly perform picking when CroppingPlanes are present. This
// isn't possible for vtkCellPicker since it doesn't link to
// the VolumeRendering classes and hence cannot access information
// about the CroppingPlanes.
//
// .SECTION See Also
// vtkPicker vtkPointPicker vtkCellPicker
//
// .SECTION Thanks
// This class was contributed to VTK by David Gobbi on behalf of Atamai Inc.

// Description:
// Set whether to pick the cropping planes of props that have them.
// If this is set, then the pick will be done on the cropping planes
// rather than on the data. The GetCroppingPlaneId() method will return
// the index of the cropping plane of the volume that was picked. This
// setting is only relevant to the picking of volumes.

// Description:
// Get the index of the cropping plane that the pick ray passed
// through on its way to the prop. This will be set regardless
// of whether PickCroppingPlanes is on. The crop planes are ordered
// as follows: xmin, xmax, ymin, ymax, zmin, zmax. If the volume is
// not cropped, the value will bet set to -1.
