Field Details

sensors

public VRMLPointingDeviceSensorNodeType[] sensors

The list of sensors held by this grouping node. If no sensors are registered, this will be null.

linkReference

public VRMLLinkNodeType linkReference

The link from this node. A grouping node only ever has one link, so this represents that information. If none is set, the value is null.

visibilityListener

public OGLVisibilityListener visibilityListener

The visibility listener that is using this node for rendering. Set by the implementing VRML node, in the picked object at the end. If none is set, the value is null.

areaListener

public OGLAreaListener areaListener

The visibility listener that is using this node for rendering. Set by the implementing VRML node, in the picked object at the end. If none is set, the value is null.

isTransform

public boolean isTransform

Flag to say that this is a node that will cause a transformation of the scene graph rather than just an aggregation. Basically only Transform nodes should set this to true. It is an optimisation flag so that we know whether to perform coordinate transformations on the picked points when dealing with point device sensors because the normal node implementation will only expose the BranchGroup/SharedGroup surrounding the VRML node's internal representation to the pick reporting. Therefore the picking code working on the internals of the J3D scene graph will have no idea about transformations, so this is a performance hint allowing faster picking. Defaults to false;

owner

public OGLTransformNodeType owner

A back pointer to the OGL node for those containing TransformGroups.

Constructor Details

OGLUserData

public OGLUserData()

Construct a new instance of the transform node and set the default values.
