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.

Set the interaction state.
|
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 arbitrary plane orientations.

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.

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.

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.

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.

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.

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.

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

Register internal Pickers in the Picking Manager.
Must be reimplemented by concrete widget representations to register their pickers.
Reimplemented from vtkWidgetRepresentation.
| void vtkCurveRepresentation::SetCurrentHandleIndex | ( | int | index | ) |
Get/Set the current handle index.
Setting the current handle index will also result in the handle being highlighted. Set to -1 to remove the highlight.
