Detailed Description

Here is the documentation for this node type, from the ISO standard.

6.12 Contour2D

The Contour2D node groups a set of curve segments to a composite contour. The children shall form a closed loop with the first point of the first child repeated as the last point of the last child and the last point of a segment repeated as the first point of the consecutive one. The segments shall be defined either by NurbsCurve2D or Polyline2D nodes and shall be enumerated in the child field in consecutive order according to the topology of the contour. 

Nested Contour2D nodes alternately specify invalid and valid regions depending on the clockwiseness of the contours. Additionally, each Contour2D may contain multiple, non-intersecting Contour2D nodes. This allows specification of multiple invalid or valid regions within a single outerlying valid or invalid region. See 4.16.4 Trimmed NURBS for a description of how clockwiseness is computed.

Constructor & Destructor Documentation

Contour2D (  const char *  name = ""  ) 
 

Construct a node with all its fields set to default value, which is equivalent to the code below: 

    		
  







  

    
      

        

          ~Contour2D

Returns a deep copy of this node, that is a fully independant node with all children (if any) also copied. This is mainly useful for instanciating protos.

Return a handle on the i th event in of the node or a "unknown" typed handle if there is no such node. Here is how i is related to fields:
    

  • 0 : addChildren
  • 1 : removeChildren
  • 2 : set_children



This function is useful, with nbEventsIn() if you want to traverse all events in of a Node.
