ContourPolyline2D : X3DNurbsControlCurveNode { SFNode [in,out] metadata NULL [X3DMetadataObject] MFVec2f [in,out] point [] (-∞,∞); }
The ContourPolyline2D node defines a piecewise linear curve segment as a part of a trimming contour in the u,v domain of a surface.
The point field specifies the end points of the piecewise linear curve.
ContourPolyline2D nodes are used as children of the Contour2D group.
