Interface NurbsOrientationInterpolator

All Superinterfaces:

X3DChildNode, X3DNode

All Known Implementing Classes:

NurbsOrientationInterpolator

public interface NurbsOrientationInterpolator
extends X3DChildNode

NurbsOrientationInterpolator describes a 3D NURBS curve and outputs interpolated orientation 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. NurbsOrientationInterpolator node tooltip: [X3DChildNode] NurbsOrientationInterpolator describes a 3D NURBS curve and outputs interpolated orientation values.

• Hint: the SFNode controlPoint field can contain a single Coordinate or CoordinateDouble node.

Package hint: This interface is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI).
