Defines API for interpolating/modifying nodes from a vtkContourRepresentation.
void PrintSelf(ostream &os, vtkIndent indent) override
Standard methods for instances of this class.
virtual int UpdateNode(vtkRenderer *, vtkContourRepresentation *, double *vtkNotUsed(node), int vtkNotUsed(idx))
The interpolator is given a chance to update the node.
virtual int InterpolateLine(vtkRenderer *ren, vtkContourRepresentation *rep, int idx1, int idx2)=0
Subclasses that wish to interpolate a line segment must implement this.
~vtkContourLineInterpolator() override
virtual void GetSpan(int nodeIndex, vtkIntArray *nodeIndices, vtkContourRepresentation *rep)
Span of the interpolator.
