Detailed Description

represent the vtkContourWidget

The vtkContourRepresentation is a superclass for various types of representations for vtkContourWidget.

Managing contour points:
The classes vtkContourRepresentationNode, vtkContourRepresentationInternals, and vtkContourRepresentationPoint manage the data structure used to represent nodes and points on a contour. A contour may contain several nodes and several additional points. Nodes are usually the result of user-clicked points on the contour. Additional points are created between nodes to generate a smooth curve using some Interpolator – see the method SetLineInterpolator.
Managing contour points:
The data structure stores both the world and display positions for every point. (This may seem like a duplication.) The default behaviour of this class is to use the WorldPosition to do all the math. Typically a point is added at a given display position. Its corresponding world position is computed using the point placer, and stored. Any query of the display position of a stored point is done via the Renderer, which computes the display position given a world position.
Managing contour points:
So why maintain the display position? Consider drawing a contour on a volume widget. You might want the contour to be located at a certain world position in the volume or you might want to be overlaid over the window like an Actor2D. The default behaviour of this class is to provide the former behaviour.
Managing contour points:
To achieve the latter behaviour, override the methods that return the display position (to return the set display position instead of computing it from the world positions) and the method BuildLines() to interpolate lines using their display positions instead of world positions.

◆ RenderOpaqueGeometry()

int vtkContourRepresentation::RenderOpaqueGeometry ( vtkViewport )
overridepure 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.

Implemented in vtkOrientedGlyphFocalPlaneContourRepresentation, and vtkOrientedGlyphContourRepresentation.

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.

◆ Initialize() [1/2]

virtual void vtkContourRepresentation::Initialize ( vtkPolyData ,

)
protectedvirtual

Build a contour representation from externally supplied PolyData.

This is very useful when you use an external program to compute a set of contour nodes (let's say based on image features) and subsequently want to build and display a contour that runs through those points. This method is protected and accessible only from vtkContourWidget::Initialize. The idlist here may be used to initialize a contour widget that uses a vtkPolygonalSurfacePointPlacer. This stores the point id's of the nodes, since the contour is drawn on the vertices of a surface mesh.
