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.

static

◆ NewInstanceInternal()

virtual vtkObjectBase* vtkCurveRepresentation::NewInstanceInternal ( ) const
protectedvirtual

Reimplemented from vtkWidgetRepresentation.

Reimplemented in vtkSplineRepresentation, and vtkPolyLineRepresentation.

◆ NewInstance()

vtkCurveRepresentation* vtkCurveRepresentation::NewInstance ( ) const

◆ PrintSelf()

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.

◆ SetInteractionState()

virtual void vtkCurveRepresentation::SetInteractionState ( int  )
virtual

Set the interaction state

◆ SetProjectToPlane()

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.

◆ GetProjectToPlane()

virtual

◆ ProjectToPlaneOff()

virtual void vtkCurveRepresentation::ProjectToPlaneOff ( )

void vtkCurveRepresentation::SetProjectionNormalToOblique ( )
inline

Definition at line 96 of file vtkCurveRepresentation.h.

◆ SetProjectionPosition()

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.

◆ GetProjectionPosition()

virtual double vtkCurveRepresentation::GetProjectionPosition ( )
virtual

◆ GetPolyData()

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.

◆ GetHandleProperty()

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.

◆ GetSelectedHandleProperty()

virtual vtkProperty* vtkCurveRepresentation::GetSelectedHandleProperty ( )
virtual

◆ GetLineProperty()

virtual vtkProperty* vtkCurveRepresentation::GetLineProperty ( )
virtual

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

◆ GetSelectedLineProperty()

virtual vtkProperty* vtkCurveRepresentation::GetSelectedLineProperty ( )
virtual

◆ SetNumberOfHandles()

virtual void vtkCurveRepresentation::SetNumberOfHandles ( int  npts)
pure virtual

Set/Get the number of handles for this widget.

Implemented in vtkSplineRepresentation, and vtkPolyLineRepresentation.

◆ GetNumberOfHandles()

virtual int vtkCurveRepresentation::GetNumberOfHandles ( )
virtual

◆ SetHandlePosition() [1/2]

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

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

◆ SetHandlePosition() [2/2]

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

◆ GetHandlePosition() [1/2]

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

◆ GetHandlePosition() [2/2]

virtual double* vtkCurveRepresentation::GetHandlePosition ( int  handle)
virtual

◆ GetHandlePositions()

virtual vtkDoubleArray* vtkCurveRepresentation::GetHandlePositions ( )
pure virtual

Implemented in vtkSplineRepresentation, and vtkPolyLineRepresentation.

◆ SetClosed()

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.

◆ GetClosed()

virtual int vtkCurveRepresentation::GetClosed ( )
virtual

◆ ClosedOn()

virtual void vtkCurveRepresentation::ClosedOn ( )
virtual

◆ ClosedOff()

virtual void vtkCurveRepresentation::ClosedOff ( )
virtual

◆ IsClosed()

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).

◆ GetSummedLength()

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.

◆ InitializeHandles()

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.

◆ BuildRepresentation()

virtual void vtkCurveRepresentation::BuildRepresentation ( )
pure virtual

These are methods that satisfy vtkWidgetRepresentation's API. Note that a version of place widget is available where the center and handle position are specified.

Implements vtkWidgetRepresentation.

Implemented in vtkSplineRepresentation, and vtkPolyLineRepresentation.

◆ ComputeInteractionState()

virtual int vtkCurveRepresentation::ComputeInteractionState ( int  X,
int  Y,
int  modify = 0 
)
virtual

Reimplemented from vtkWidgetRepresentation.

◆ StartWidgetInteraction()

virtual void vtkCurveRepresentation::StartWidgetInteraction ( double  e[2])
virtual

Reimplemented from vtkWidgetRepresentation.

virtual

Reimplemented from vtkWidgetRepresentation.

◆ EndWidgetInteraction()

virtual void vtkCurveRepresentation::EndWidgetInteraction ( double  e[2])
virtual

Reimplemented from vtkWidgetRepresentation.

◆ GetBounds()

virtual double* vtkCurveRepresentation::GetBounds ( void  )
virtual

Methods to make this class behave as a vtkProp. They are repeated here (from the vtkProp superclass) as a reminder to the widget implementor. Failure to implement these methods properly may result in the representation not appearing in the scene (i.e., not implementing the Render() methods properly) or leaking graphics resources (i.e., not implementing ReleaseGraphicsResources() properly).

Reimplemented from vtkWidgetRepresentation.

◆ ReleaseGraphicsResources()

virtual void vtkCurveRepresentation::ReleaseGraphicsResources ( vtkWindow *  )
virtual

Methods supporting, and required by, the rendering process.

Reimplemented from vtkWidgetRepresentation.

◆ RenderOpaqueGeometry()

virtual int vtkCurveRepresentation::RenderOpaqueGeometry ( vtkViewport *  )
virtual

WARNING: INTERNAL METHOD - NOT INTENDED FOR GENERAL USE DO NOT USE THESE METHODS OUTSIDE OF THE RENDERING PROCESS All concrete subclasses must be able to render themselves. There are four key render methods in vtk and they correspond to four different points in the rendering cycle. Any given prop may implement one or more of these methods. The first method is intended for rendering all opaque geometry. The second method is intended for rendering all translucent polygonal geometry. The third one is intended for rendering all translucent volumetric geometry. Most of the volume rendering mappers draw their results during this third method. The last method is to render any 2D annotation or overlays. Each of these methods return an integer value indicating whether or not this render method was applied to this data.

Reimplemented from vtkProp.

◆ RenderTranslucentPolygonalGeometry()

virtual int vtkCurveRepresentation::RenderTranslucentPolygonalGeometry ( vtkViewport *  )
virtual

Reimplemented from vtkProp.

◆ RenderOverlay()

virtual int vtkCurveRepresentation::RenderOverlay ( vtkViewport *  )
virtual

Reimplemented from vtkProp.

◆ HasTranslucentPolygonalGeometry()

virtual int vtkCurveRepresentation::HasTranslucentPolygonalGeometry ( )
virtual

WARNING: INTERNAL METHOD - NOT INTENDED FOR GENERAL USE DO NOT USE THESE METHODS OUTSIDE OF THE RENDERING PROCESS Does this prop have some translucent polygonal geometry? This method is called during the rendering process to know if there is some translucent polygonal geometry. A simple prop that has some translucent polygonal geometry will return true. A composite prop (like vtkAssembly) that has at least one sub-prop that has some translucent polygonal geometry will return true. Default implementation return false.

Reimplemented from vtkWidgetRepresentation.

◆ SetLineColor()

void vtkCurveRepresentation::SetLineColor ( double  r,
double  g,
double  b 
)

Convenience method to set the line color. Ideally one should use GetLineProperty()->SetColor().
