To create an instance of class vtkPolygonalSurfaceContourLineInterpolator, simply invoke its constructor as follows
obj = vtkPolygonalSurfaceContourLineInterpolator
obj
is an instance of the vtkPolygonalSurfaceContourLineInterpolator class.
string = obj.GetClassName ()
- Standard methods for instances of this class.
int = obj.IsA (string name)
- Standard methods for instances of this class.
vtkPolygonalSurfaceContourLineInterpolator = obj.NewInstance ()
- Standard methods for instances of this class.
vtkPolygonalSurfaceContourLineInterpolator = obj.SafeDownCast (vtkObject o)
- Standard methods for instances of this class.
int = obj.InterpolateLine (vtkRenderer ren, vtkContourRepresentation rep, int idx1, int idx2)
- 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.
int = obj.UpdateNode (vtkRenderer , vtkContourRepresentation , double , int )
- 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.
obj.SetDistanceOffset (double )
- Height offset at which points may be placed on the polygonal surface.
If you specify a non-zero value here, be sure to have computed vertex
normals on your input polygonal data. (easily done with
vtkPolyDataNormals).
double = obj.GetDistanceOffset ()
- Height offset at which points may be placed on the polygonal surface.
If you specify a non-zero value here, be sure to have computed vertex
normals on your input polygonal data. (easily done with
vtkPolyDataNormals).
