Usage

This class is a concrete representation for the
vtkImplicitPlaneWidget2. It represents an infinite plane
defined by a normal and point in the context of a bounding
box. Through interaction with the widget, the plane can be
manipulated by adjusting the plane normal or moving the
origin point.
To use this representation, you normally define a (plane)
origin and (plane) normal. The PlaceWidget() method is also
used to intially position the representation.
To create an instance of class
vtkImplicitPlaneRepresentation, simply invoke its
constructor as follows

    obj = vtkImplicitPlaneRepresentation



 Methods

The class vtkImplicitPlaneRepresentation has several methods
that can be used. They are listed below. Note that the
documentation is translated automatically from the VTK
sources, and may not be completely intelligible. When in
doubt, consult the VTK website. In the methods listed below,
obj is an instance of the vtkImplicitPlaneRepresentation
class.

  underlying PolyData (which represents the plane).
* obj.GetPlane (vtkPlane plane) - Get the implicit function
  for the plane. The user must provide the instance of the
  class vtkPlane. Note that vtkPlane is a subclass of
  vtkImplicitFunction, meaning that it can be used by a
  variety of filters to perform clipping, cutting, and
  selection of data.

  API. This will change the state of the widget to match
  changes that have been made to the underlying

  )

* obj.SetInteractionState (int ) - The interaction state may
  be set from a widget (e.g., vtkImplicitPlaneWidget2) or
  other object. This controls how the interaction with the
  widget proceeds. Normally this method is used as part of a
  handshaking process with the widget: First
  ComputeInteractionState() is invoked that returns a state
  based on geometric considerations (i.e., cursor near a
  widget feature), then based on events, the widget may
  modify this further.
* int = obj.GetInteractionStateMinValue () - The interaction
  state may be set from a widget (e.g.,
  vtkImplicitPlaneWidget2) or other object. This controls
  how the interaction with the widget proceeds. Normally
  this method is used as part of a handshaking process with
  the widget: First ComputeInteractionState() is invoked
  that returns a state based on geometric considerations
  (i.e., cursor near a widget feature), then based on
  events, the widget may modify this further.
* int = obj.GetInteractionStateMaxValue () - The interaction
  state may be set from a widget (e.g.,
  vtkImplicitPlaneWidget2) or other object. This controls
  how the interaction with the widget proceeds. Normally
  this method is used as part of a handshaking process with
  the widget: First ComputeInteractionState() is invoked
  that returns a state based on geometric considerations
  (i.e., cursor near a widget feature), then based on
  events, the widget may modify this further.
* obj.SetRepresentationState (int ) - Sets the visual
  appearance of the representation based on the state it is
  in. This state is usually the same as InteractionState.
* int = obj.GetRepresentationState () - Sets the visual
  appearance of the representation based on the state it is
  in. This state is usually the same as InteractionState.
