Detailed Description

ray-cast picker enhanced for volumes

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.

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkCellPicker.

virtual void vtkVolumePicker::SetPickCroppingPlanes ( vtkTypeBool  )
virtual

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.

virtual void vtkVolumePicker::PickCroppingPlanesOn ( )
virtual

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.

virtual void vtkVolumePicker::PickCroppingPlanesOff ( )
virtual

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.

virtual vtkTypeBool vtkVolumePicker::GetPickCroppingPlanes ( )
virtual

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.

virtual int vtkVolumePicker::GetCroppingPlaneId ( )
virtual

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.
