Detailed Description

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

6.55 Polyline2D

The Polyline2D node defines a piecewise linear curve segment as a part of a trimming contour in the u-v domain of a surface.

point specifies the end points of the piecewise linear curve.

Polyline2D are used as children to the Contour2D group.

Polyline2D (  const char *  name = ""  ) 
 

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

    		
  







  

    
      

        

          ~Polyline2D

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. emarks This class has no eventIn. This function is useful, with nbEventsIn() if you want to traverse all events in of a Node.
