X3D Reference



ContourPolyline2D defines a linear curve segment as part of a trimming contour in the u-v domain of a NURBS surface. NurbsCurve2D and ContourPolyline2D nodes that together form a closed contour, defined in the u-v parametric space of a NURBS surface, may be used as children in a Contour2D node.

The ContourPolyline2D node belongs to the NURBS component and its container field is children. It is available since X3D version 3.0 or later.



SFNode [in, out] metadata NULL [X3DMetadataObject]

Metadata are not part of the X3D world and not interpreted by the X3D browser, but they can be accessed via the ECMAScript interface.

MFVec2d [in, out] controlPoint [ ] (-∞, ∞)

ControlPoint specifies the end points of each segment of the piecewise linear curve.



  • ContourPolyline2D is not a renderable geometry node.
