Section: Visualization Toolkit Widget Classes
To create an instance of class vtkParallelopipedRepresentation, simply invoke its constructor as follows
obj = vtkParallelopipedRepresentation
obj
is an instance of the vtkParallelopipedRepresentation class.
string = obj.GetClassName ()
- Standard methods for instances of this class.
int = obj.IsA (string name)
- Standard methods for instances of this class.
vtkParallelopipedRepresentation = obj.NewInstance ()
- Standard methods for instances of this class.
vtkParallelopipedRepresentation = obj.SafeDownCast (vtkObject o)
- Standard methods for instances of this class.
obj.GetActors (vtkPropCollection pc)
- Methods to satisfy the superclass.
obj.PlaceWidget (double bounds[6])
- Place the widget in the scene. You can use either of the two APIs :
1) PlaceWidget( double bounds[6] )
Creates a cuboid conforming to the said bounds.
2) PlaceWidget( double corners[8][3] )
Creates a parallelopiped with corners specified. The order in
which corners are specified must obey the following rule:
Corner 0 - 1 - 2 - 3 - 0 forms a face
Corner 4 - 5 - 6 - 7 - 4 forms a face
Corner 0 - 4 - 5 - 1 - 0 forms a face
Corner 1 - 5 - 6 - 2 - 1 forms a face
Corner 2 - 6 - 7 - 3 - 2 forms a face
Corner 3 - 7 - 4 - 0 - 3 forms a face
obj.SetInteractionState (int )
- The interaction state may be set from a widget (e.g., PointWidget)
or other object. This controls how the interaction with the
widget proceeds.
obj.GetBoundingPlanes (vtkPlaneCollection pc)
- Get the bounding planes of the object. The first 6 planes will
be bounding planes of the parallelopiped. If in chair mode, three
additional planes will be present. The last three planes will be those
of the chair. The normals of all the planes will point into the object.
obj.GetPolyData (vtkPolyData pd)
- The parallelopiped polydata.
double = obj.GetBounds ()
- The parallelopiped polydata.
obj.SetHandleProperty (vtkProperty )
- Set/Get the handle properties.
obj.SetHoveredHandleProperty (vtkProperty )
- Set/Get the handle properties.
obj.SetSelectedHandleProperty (vtkProperty )
- Set/Get the handle properties.
vtkProperty = obj.GetHandleProperty ()
- Set/Get the handle properties.
vtkProperty = obj.GetHoveredHandleProperty ()
- Set/Get the handle properties.
vtkProperty = obj.GetSelectedHandleProperty ()
- Set/Get the handle properties.
obj.SetHandleRepresentation (vtkHandleRepresentation handle)
vtkHandleRepresentation = obj.GetHandleRepresentation (int index)
obj.HandlesOn ()
- Turns the visibility of the handles on/off. Sometimes they may get in
the way of visualization.
obj.HandlesOff ()
- Turns the visibility of the handles on/off. Sometimes they may get in
the way of visualization.
vtkProperty = obj.GetFaceProperty ()
- Get the face properties. When a face is being translated, the face gets
highlighted with the SelectedFaceProperty.
vtkProperty = obj.GetSelectedFaceProperty ()
- Get the face properties. When a face is being translated, the face gets
highlighted with the SelectedFaceProperty.
vtkProperty = obj.GetOutlineProperty ()
- Get the outline properties. These are the properties with which the
parallelopiped wireframe is rendered.
vtkProperty = obj.GetSelectedOutlineProperty ()
- Get the outline properties. These are the properties with which the
parallelopiped wireframe is rendered.
obj.BuildRepresentation ()
- This actually constructs the geometry of the widget from the various
data parameters.
obj.ReleaseGraphicsResources (vtkWindow w)
- Methods required by vtkProp superclass.
int = obj.RenderOverlay (vtkViewport viewport)
- Methods required by vtkProp superclass.
int = obj.RenderOpaqueGeometry (vtkViewport viewport)
- Methods required by vtkProp superclass.
int = obj.ComputeInteractionState (int X, int Y, int modify)
- Given and x-y display coordinate, compute the interaction state of
the widget.
obj.Translate (double translation[3])
obj.Translate (int X, int Y)
obj.Scale (int X, int Y)
obj.PositionHandles ()
- Synchronize the parallelopiped handle positions with the
Polygonal datastructure.
obj.SetMinimumThickness (double )
- Minimum thickness for the parallelopiped. User interactions cannot make
any individual axis of the parallopiped thinner than this value.
Default is 0.05 expressed as a fraction of the diagonal of the bounding
box used in the PlaceWidget() invocation.
double = obj.GetMinimumThickness ()
- Minimum thickness for the parallelopiped. User interactions cannot make
any individual axis of the parallopiped thinner than this value.
Default is 0.05 expressed as a fraction of the diagonal of the bounding
box used in the PlaceWidget() invocation.
