All Implemented Interfaces:

X3DChildNode, X3DNode, NurbsPositionInterpolator
```
public class NurbsPositionInterpolatorObject
extends X3DConcreteNode
implements NurbsPositionInterpolator
```
X3D node tooltip: [X3DChildNode] NurbsPositionInterpolator describes a 3D NURBS curve and outputs interpolated position values.
- Hint: the SFNode controlPoints field can contain a single Coordinate or CoordinateDouble 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.
