public class ForcePhysicsModel
extends X3DConcreteNode
implements ForcePhysicsModel

ForcePhysicsModel applies a constant force value to the particles.

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. ForcePhysicsModel node tooltip: (X3D version 3.2 or later) [X3DParticlePhysicsModelNode] ForcePhysicsModel applies a constant force value to the particles.

• Hint: force may act in any given direction vector at any strength.

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.

Add comments as String[] array to contained commentsList.

Specified by:

addComments in class X3DConcreteElement

Parameters:

newComments - array of comments

Returns:

ForcePhysicsModel - namely this same object to allow sequential method pipelining (i.e. consecutive setAttribute method invocations).

addComments

findElementByNameValue

public X3DConcreteElement findElementByNameValue(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()
