Contour(contour_points)  

The Contour class provides an interface for creating a contour          
segmentation. A contur segmentation is defined by a set of 3D points.   

Args: 
  contour_points (list([float,float,float])): The list of 3D points     
     defining the contour.                                              

get_center()  
   
   Get the center of the polygon segmentation. 
   
   
   Returns (list([float,float,float]): The polygon segmentation center. 

get_id()  
   
   Get the contour ID. 
   
   Returns int: The contour ID. 

get_normal()  
   
   Get the normal of the polygon segmentation. 
   
   
   Returns (list([float,float,float]): The polygon segmentation normal. 

get_path_point()  
   
   Get the contour path point. 
   
   Returns dict(pos:[x,y,z], tangent:[x,y,z], rotation:[x,y,z]): The contour path point. 

get_points()  
   
   Get the segmentation contour points. 
   
   Returns list([x,y,z]): The list of contour points. 

get_vtk_polydata()  
   
   Get the contour type. 
   
   Returns (str): contour type. 

get_type()  
   
   Get the contour type. 
   
   Returns (str): contour type. 

set_contour_points(contour_points)  
   
   Set the contour points for a contour segmentation. 
   
   Args: 
     points (list(list([float,float,float])): The list of contour points.
