public class NurbsCurve2DObject

implements NurbsCurve2D
```
X3D node tooltip: [X3DNurbsControlCurveNode] NurbsCurve2D defines a trimming segment that is part of a trimming contour in the u-v domain of a 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.
- Warning: NurbsCurve2D is not a renderable geometry node.
Package hint: This org.web3d.x3d.jsail concrete class is used for implementing a standalone X3D object as a Plain Old Java Object (POJO). If you are writing Java code for use inside an X3D Script node, compile separate code using only the org.web3d.x3d.sai package instead.
