Detailed Description

vtkWidgetRepresentation base class for a widget that represents an curve that connects control points.

Base class for widgets used to define curves from points, such as vtkPolyLineRepresentation and vtkSplineRepresentation. This class uses handles, the number of which can be changed, to represent the points that define the curve. The handles can be picked can be picked on the curve itself to translate or rotate it in the scene.

void vtkCurveRepresentation::PrintSelf	(	ostream &	os,
		vtkIndent	indent

virtual

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 vtkObject.

Reimplemented in vtkSplineRepresentation, and vtkPolyLineRepresentation.

virtual void vtkCurveRepresentation::SetInteractionState ( int )

virtual

Set the interaction state

virtual void vtkCurveRepresentation::SetProjectToPlane ( int )

virtual

Force the 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 curve to the plane if it is originally 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 vtkCurveRepresentation::GetProjectToPlane ( )

virtual

Force the 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 curve to the plane if it is originally 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 vtkCurveRepresentation::ProjectToPlaneOn ( )

virtual

Force the 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 curve to the plane if it is originally 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 vtkCurveRepresentation::ProjectToPlaneOff ( )

virtual

Force the 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 curve to the plane if it is originally 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.

void vtkCurveRepresentation::SetProjectionPosition ( double position )

Set the position of poly line 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 poly line points when Projection normal is set to 3 for arbritrary plane orientations.

virtual double vtkCurveRepresentation::GetProjectionPosition ( )

virtual

Set the position of poly line 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 poly line points when Projection normal is set to 3 for arbritrary plane orientations.

virtual void vtkCurveRepresentation::GetPolyData ( vtkPolyData * pd )

pure virtual

Grab the polydata (including points) that defines the interpolating curve. 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.

Implemented in vtkSplineRepresentation, and vtkPolyLineRepresentation.

virtual vtkProperty* vtkCurveRepresentation::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* vtkCurveRepresentation::GetSelectedHandleProperty ( )

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* vtkCurveRepresentation::GetLineProperty ( )

virtual

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

virtual vtkProperty* vtkCurveRepresentation::GetSelectedLineProperty ( )

virtual

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

virtual void vtkCurveRepresentation::SetNumberOfHandles ( int npts )

pure virtual

Set/Get the number of handles for this widget.

Implemented in vtkSplineRepresentation, and vtkPolyLineRepresentation.

virtual int vtkCurveRepresentation::GetNumberOfHandles ( )

virtual

Set/Get the number of handles for this widget.

virtual void vtkCurveRepresentation::SetHandlePosition	(	int	handle,

	)

virtual

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

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

virtual

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

virtual void vtkCurveRepresentation::GetHandlePosition	(	int	handle,
		double	xyz[3]
	)

virtual

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

virtual double* vtkCurveRepresentation::GetHandlePosition ( int handle )

virtual

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

virtual vtkDoubleArray* vtkCurveRepresentation::GetHandlePositions ( )

pure virtual

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

Implemented in vtkSplineRepresentation, and vtkPolyLineRepresentation.

void vtkCurveRepresentation::SetClosed ( int closed )

Control whether the curve is open or closed. A closed forms a continuous loop: the first and last points are the same. A minimum of 3 handles are required to form a closed loop.

virtual int vtkCurveRepresentation::GetClosed ( )

virtual

Control whether the curve is open or closed. A closed forms a continuous loop: the first and last points are the same. A minimum of 3 handles are required to form a closed loop.

virtual void vtkCurveRepresentation::ClosedOn ( )

virtual

Control whether the curve is open or closed. A closed forms a continuous loop: the first and last points are the same. A minimum of 3 handles are required to form a closed loop.

virtual void vtkCurveRepresentation::ClosedOff ( )

virtual

Control whether the curve is open or closed. A closed forms a continuous loop: the first and last points are the same. A minimum of 3 handles are required to form a closed loop.

int vtkCurveRepresentation::IsClosed ( )

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

virtual double vtkCurveRepresentation::GetSummedLength ( )

pure virtual

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

Implemented in vtkSplineRepresentation, and vtkPolyLineRepresentation.

virtual void vtkCurveRepresentation::InitializeHandles ( vtkPoints * points )

pure virtual

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

Implemented in vtkSplineRepresentation, and vtkPolyLineRepresentation.

virtual void vtkCurveRepresentation::BuildRepresentation ( )

pure virtual
