public class NurbsPositionInterpolator
extends X3DConcreteNode
implements NurbsPositionInterpolator

NurbsPositionInterpolator describes a 3D NURBS curve and outputs interpolated position values.

Warning: this is an abstract interface that cannot be instantiated as a concrete object. Java programmers typically only need to use concrete objects provided by the org.web3d.x3d.jsail classes. NurbsPositionInterpolator node tooltip: [X3DChildNode] NurbsPositionInterpolator describes a 3D NURBS curve and outputs interpolated position values.

• Hint: the SFNode controlPoint 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.
