vtkContourLineInterpolator

Section: Visualization Toolkit Widget Classes

Usage

vtkContourLineInterpolator is an abstract base class for interpolators that work are used by the contour representation class to interpolate and/or modify nodes in a contour. Subclasses must override the virtual method: \c 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, \c 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.

To create an instance of class vtkContourLineInterpolator, simply invoke its constructor as follows

  obj = vtkContourLineInterpolator
