All Implemented Interfaces:: X3DChildNode, X3DNode, PositionInterpolator, X3DInterpolatorNode

public class PositionInterpolatorObject
extends X3DConcreteNode
implements PositionInterpolator

PositionInterpolator generates a series of 3-tuple SFVec3f values.

X3D node tooltip: [X3DInterpolatorNode] PositionInterpolator generates a series of 3-tuple SFVec3f values. Authors can ROUTE value_changed output events to a Transform node's translation field or another SFVec3f field.

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.

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.
