Detailed Description

vtkWidgetRepresentation for a spline.

vtkSplineRepresentation is a vtkWidgetRepresentation for a spline. This 3D widget defines a spline that can be interactively placed in a scene. The spline has handles, the number of which can be changed, plus it can be picked on the spline itself to translate or rotate it in the scene. This is based on vtkSplineWidget.

virtual void vtkSplineRepresentation::SetInteractionState ( int   )  [virtual]

virtual void vtkSplineRepresentation::SetProjectToPlane ( int   )  [virtual]

Force the spline widget to be projected onto one of the orthogonal planes. Remember that when the InteractionState changes, a ModifiedEvent is invoked. This can be used to snap the spline to the plane if it is orginally not aligned. The normal in SetProjectionNormal is 0,1,2 for YZ,XZ,XY planes respectively and 3 for arbitrary oblique planes when the widget is tied to a vtkPlaneSource.

virtual int vtkSplineRepresentation::GetProjectToPlane (  )  [virtual]

Force the spline widget to be projected onto one of the orthogonal planes. Remember that when the InteractionState changes, a ModifiedEvent is invoked. This can be used to snap the spline to the plane if it is orginally not aligned. The normal in SetProjectionNormal is 0,1,2 for YZ,XZ,XY planes respectively and 3 for arbitrary oblique planes when the widget is tied to a vtkPlaneSource.

virtual void vtkSplineRepresentation::ProjectToPlaneOn (  )  [virtual]

Force the spline widget to be projected onto one of the orthogonal planes. Remember that when the InteractionState changes, a ModifiedEvent is invoked. This can be used to snap the spline to the plane if it is orginally not aligned. The normal in SetProjectionNormal is 0,1,2 for YZ,XZ,XY planes respectively and 3 for arbitrary oblique planes when the widget is tied to a vtkPlaneSource.

virtual void vtkSplineRepresentation::ProjectToPlaneOff (  )  [virtual]

Force the spline widget to be projected onto one of the orthogonal planes. Remember that when the InteractionState changes, a ModifiedEvent is invoked.

void vtkSplineRepresentation::SetProjectionPosition ( double  position  ) 

Set the position of spline handles and points in terms of a plane's position. i.e., if ProjectionNormal is 0, all of the x-coordinate values of the points are set to position. Any value can be passed (and is ignored) to update the spline points when Projection normal is set to 3 for arbritrary plane orientations.

virtual double vtkSplineRepresentation::GetProjectionPosition (  )  [virtual]

Set the position of spline handles and points in terms of a plane's position. i.e., if ProjectionNormal is 0, all of the x-coordinate values of the points are set to position. Any value can be passed (and is ignored) to update the spline points when Projection normal is set to 3 for arbritrary plane orientations.

void vtkSplineRepresentation::GetPolyData ( vtkPolyData pd  ) 

Grab the polydata (including points) that defines the spline. The polydata consists of points and line segments numbering Resolution + 1 and Resoltuion, respectively. Points are guaranteed to be up-to-date when either the InteractionEvent or EndInteraction events are invoked. The user provides the vtkPolyData and the points and polyline are added to it.

virtual vtkProperty* vtkSplineRepresentation::GetHandleProperty (  )  [virtual]

Set/Get the handle properties (the spheres are the handles). The properties of the handles when selected and unselected can be manipulated.

virtual vtkProperty* vtkSplineRepresentation::GetSelectedHandleProperty (  )  [virtual]

Set/Get the line properties. The properties of the line when selected and unselected can be manipulated.

virtual vtkProperty* vtkSplineRepresentation::GetSelectedLineProperty (  )  [virtual]

virtual void vtkSplineRepresentation::SetParametricSpline ( vtkParametricSpline  )  [virtual]

Set the parametric spline object. Through vtkParametricSpline's API, the user can supply and configure one of currently two types of spline: vtkCardinalSpline, vtkKochanekSpline. The widget controls the open or closed configuration of the spline. WARNING: The widget does not enforce internal consistency so that all three are of the same type.

virtual vtkParametricSpline* vtkSplineRepresentation::GetParametricSpline (  )  [virtual]

Set the parametric spline object. Through vtkParametricSpline's API, the user can supply and configure one of currently two types of spline: vtkCardinalSpline, vtkKochanekSpline. The widget controls the open or closed configuration of the spline. WARNING: The widget does not enforce internal consistency so that all three are of the same type.

void vtkSplineRepresentation::SetHandlePosition ( int  handle,
double  x,
double  y,
double  z 
)

Set/Get the position of the spline handles. Call GetNumberOfHandles to determine the valid range of handle indices.

void vtkSplineRepresentation::SetHandlePosition ( int  handle,
double  xyz[3] 
)

Set/Get the position of the spline handles. Call GetNumberOfHandles to determine the valid range of handle indices.

void vtkSplineRepresentation::SetClosed ( int  closed  ) 

Control whether the spline is open or closed. A closed spline forms a continuous loop: the first and last points are the same, and derivatives are continuous. A minimum of 3 handles are required to form a closed loop. This method enforces consistency with user supplied subclasses of vtkSpline.

virtual int vtkSplineRepresentation::GetClosed (  )  [virtual]

Control whether the spline is open or closed. A closed spline forms a continuous loop: the first and last points are the same, and derivatives are continuous. A minimum of 3 handles are required to form a closed loop. This method enforces consistency with user supplied subclasses of vtkSpline.

virtual void vtkSplineRepresentation::ClosedOn (  )  [virtual]

Control whether the spline is open or closed. A closed spline forms a continuous loop: the first and last points are the same, and derivatives are continuous. A minimum of 3 handles are required to form a closed loop. This method enforces consistency with user supplied subclasses of vtkSpline.

virtual void vtkSplineRepresentation::ClosedOff (  )  [virtual]

Control whether the spline is open or closed. A closed spline forms a continuous loop: the first and last points are the same, and derivatives are continuous. A minimum of 3 handles are required to form a closed loop. This method enforces consistency with user supplied subclasses of vtkSpline.

int vtkSplineRepresentation::IsClosed (  ) 

Convenience method to determine whether the spline is closed in a geometric sense. The widget may be set "closed" but still be geometrically open (e.g., a straight line).

double vtkSplineRepresentation::GetSummedLength (  ) 

Get the approximate vs. the true arc length of the spline. Calculated as the summed lengths of the individual straight line segments. Use SetResolution to control the accuracy.

void vtkSplineRepresentation::InitializeHandles ( vtkPoints points  ) 

Convenience method to allocate and set the handles from a vtkPoints instance. If the first and last points are the same, the spline sets Closed to the on InteractionState and disregards the last point, otherwise Closed remains unchanged.
