public class PositionInterpolator
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.
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.

    • findElementByNameValue

      public X3DConcreteElement findElementByNameValue​(java.lang.String nameValue)
      Recursive method to provide object reference to node or statement by name attribute, if found as part of this element or in a contained element. Elements with name fields include meta, Metadata* nodes, field/fieldValue, ProtoDeclare/ExternProtoDeclare/ProtoInstance, CAD and HAnim nodes.

      Warning: first start with findAncestorScene() to check entire scene graph, or findAncestorX3D() to check entire model document.

      Warning: more than one element may be found that has the same name, this method does not handle that case.
      Specified by:
      findElementByNameValue in class X3DConcreteElement
      Parameters:
      nameValue - is value of the name field being searched for in this element and child elements(if any)
      Returns:
      object reference to found element, null otherwise
      See Also:
      findNodeByDEF(String), X3DConcreteElement.hasAncestorScene(), X3DConcreteElement.findAncestorX3D()
    • findElementByNameValue

      public X3DConcreteElement findElementByNameValue​(java.lang.String nameValue, java.lang.String elementName)
      Recursive method to provide object reference to node or statement by name attribute, if found as part of this element or in a contained element. Elements with name fields include meta, Metadata* nodes, field/fieldValue, ProtoDeclare/ExternProtoDeclare/ProtoInstance, CAD and HAnim nodes.

      Warning: first start with findAncestorScene() to check entire scene graph, or findAncestorX3D() to check entire model document.

      Warning: more than one element may be found that has the same name, this method does not handle that case.
      Specified by:
      findElementByNameValue in class X3DConcreteElement
      Parameters:
      nameValue - is value of the name field being searched for in this element and child elements(if any)
      elementName - identifies the element of interest (meta MetadataString ProtoDeclare CADassembly ProtoInstance HAnimHumanoid etc.)
      Returns:
      object reference to found element, null otherwise
      See Also:
      findNodeByDEF(String), X3DConcreteElement.hasAncestorScene(), X3DConcreteElement.findAncestorX3D()
    • hasElementByNameValue

      public boolean hasElementByNameValue​(java.lang.String nameValue, java.lang.String elementName)
      Recursive method to determine whether node or statement with given name attribute is found, meaning both objects are attached to same scene graph.
      Parameters:
      nameValue - is value of the name field being searched for in this element and child elements(if any)
      elementName - identifies the element of interest (meta MetadataString ProtoDeclare CADassembly ProtoInstance HAnimHumanoid etc.)
      Returns:
      whether node is found
      See Also:
      findElementByNameValue(String, String)
    • findNodeByDEF

      public X3DConcreteNode findNodeByDEF​(java.lang.String DEFvalue)
      Recursive method to provide object reference to node by DEF, if found as this node or in a contained node.

      Warning: first start with findAncestorScene() to check entire scene graph, or findAncestorX3D() to check entire model document.

      Warning: more than one element may be found that has the same DEF, this method does not handle that case.
      Specified by:
      findNodeByDEF in class X3DConcreteElement
      Parameters:
      DEFvalue - is value of the name field being searched for in this element and child elements(if any)
      Returns:
      object reference to found node, null otherwise
      See Also:
      findElementByNameValue(String), X3DConcreteElement.hasAncestorScene(), X3DConcreteElement.findAncestorX3D()
    • hasNodeByDEF

      public boolean hasNodeByDEF​(java.lang.String DEFvalue)
      Recursive method to determine whether node with DEFvalue is found, meaning both objects are attached to same scene graph.
      Parameters:
      DEFvalue - is value of the name field being searched for in this element and child elements(if any)
      Returns:
      whether node is found
      See Also:
      findNodeByDEF(String)
    • validate

      public java.lang.String validate()
      Recursive method to validate this element plus all contained nodes and statements, using both datatype-specification value checks and regular expression (regex) checking of corresponding string values.
      Specified by:
      validate in class X3DConcreteElement
      Returns:
      validation results (if any)
