Defines API for interpolating/modifying nodes from a vtkContourRepresentation.
vtkContourLineInterpolator is an abstract base class for interpolators that are used by the vtkContourRepresentation class to interpolate and/or modify nodes in a contour. Subclasses must override the virtual method InterpolateLine
. This is used by the contour representation to give the interpolator a chance to define an interpolation scheme between nodes. See vtkBezierContourLineInterpolator for a concrete implementation. Subclasses may also override UpdateNode
. This provides a way for the representation to give the interpolator a chance to modify the nodes, as the user constructs the contours. For instance, a sticky contour widget may be implemented that moves nodes to nearby regions of high gradient, to be used in contour-guided segmentation.

Subclasses that wish to interpolate a line segment must implement this.
For instance vtkBezierContourLineInterpolator adds nodes between idx1 and idx2, that allow the contour to adhere to a bezier curve.
Implemented in vtkBezierContourLineInterpolator, vtkDijkstraImageContourLineInterpolator, vtkLinearContourLineInterpolator, vtkPolygonalSurfaceContourLineInterpolator, vtkTerrainContourLineInterpolator, and vtkPolyDataContourLineInterpolator.
|
virtual |
The interpolator is given a chance to update the node.
For instance, the vtkImageContourLineInterpolator updates the idx'th node in the contour, so it automatically sticks to edges in the vicinity as the user constructs the contour. Returns 0 if the node (world position) is unchanged.
Reimplemented in vtkPolygonalSurfaceContourLineInterpolator, vtkTerrainContourLineInterpolator, and vtkPolyDataContourLineInterpolator.
|
virtual |
Span of the interpolator.
ie. the number of control points its supposed to interpolate given a node.
The first argument is the current nodeIndex. ie, you'd be trying to interpolate between nodes "nodeIndex" and "nodeIndex-1", unless you're closing the contour in which case, you're trying to interpolate "nodeIndex" and "Node=0".
The node span is returned in a vtkIntArray. The default node span is 1 (ie. nodeIndices is a 2 tuple (nodeIndex, nodeIndex-1)). However, it need not always be 1. For instance, cubic spline interpolators, which have a span of 3 control points, it can be larger. See vtkBezierContourLineInterpolator for instance.
