Class SplinePositionInterpolator

java.lang.Object

org.web3d.x3d.jsail.X3DConcreteElement

org.web3d.x3d.jsail.X3DConcreteNode

org.web3d.x3d.jsail.Interpolation.SplinePositionInterpolator

All Implemented Interfaces:

X3DChildNode, X3DNode, SplinePositionInterpolator, X3DInterpolatorNode

public class SplinePositionInterpolator
extends X3DConcreteNode
implements SplinePositionInterpolator

SplinePositionInterpolator performs non-linear interpolation among paired lists of 3-tuple values and velocities to produce an SFVec3f value_changed output event.

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. SplinePositionInterpolator node tooltip: (X3D version 3.2 or later) [X3DInterpolatorNode] SplinePositionInterpolator performs non-linear interpolation among paired lists of 3-tuple values and velocities to produce an SFVec3f value_changed output event.

• Hint: typical input connection is ROUTE someTimeSensorDEF.fraction_changed TO thisInterpolatorDEF.set_fraction
• Hint: typical output connection is ROUTE thisInterpolatorDEF.value_changed TO someDestinationNodeDEF.set_someAttribute.
• Warning: requires X3D profile='Full' or else include <component name='Interpolation' level='4'/>

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.
