◆ InterpolateLine()

int vtkPolyDataContourLineInterpolator::InterpolateLine ( vtkRenderer ren,
vtkContourRepresentation rep,
int  idx1,
int  idx2 
)
overridepure virtual

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.

Implements vtkContourLineInterpolator.

Implemented in vtkPolygonalSurfaceContourLineInterpolator.

◆ UpdateNode()

int vtkPolyDataContourLineInterpolator::UpdateNode ( vtkRenderer ,
vtkContourRepresentation ,
double *  vtkNotUsednode,
int   vtkNotUsedidx 
)
overridepure virtual

The interpolator is given a chance to update the node.

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 from vtkContourLineInterpolator.

Implemented in vtkPolygonalSurfaceContourLineInterpolator.

◆ GetPolys()
