Field Details

childExternalList

protected List<VRMLNode> childExternalList

List of external nodes that are contained in the child nodes

Constructor Details

OGLGeoLOD

public OGLGeoLOD()

Construct a default instance of this node. The defaults are set by the VRML specification.

OGLGeoLOD

public OGLGeoLOD(VRMLNodeType node)

Construct a new instance of this node based on the details from the given node. If the node is not a group node, an exception will be thrown. It does not copy the children nodes, just this node.

Parameters:

node - The node to copy

Throws:

IllegalArgumentException - The node is not a Group node

Method Details

getContainedScene

public BasicScene getContainedScene()

Description copied from interface: VRMLExecutionSpace

Get the contained scene graph that this instance has. This represents everything about the internal scene that the node declaration wraps. This is a real-time representation so that if it the nodes contains a script that changes the internal representation then this instance will be updated to reflect and changes made.

Specified by:

getContainedScene in interface VRMLExecutionSpace

Returns:

The scene contained by this node instance

allEventsComplete

public void allEventsComplete()

Notification that the rendering of the event model is complete and that rendering is about to begin. Used to update the scene graph with the loaded scene structure at the end of the frame to avoid issues with multiple access to the scene graph.

Specified by:

allEventsComplete in interface FrameStateListener

Overrides:

allEventsComplete in class AbstractNode

getSceneGraphObject

public org.j3d.aviatrix3d.SceneGraphObject getSceneGraphObject()

Get the OpenGL scene graph object representation of this node. This will need to be cast to the appropriate parent type when being used.

Specified by:

getSceneGraphObject in interface OGLVRMLNode

Returns:

The OGL representation.

setupFinished

public void setupFinished()

Notification that the construction phase of this node has finished. If the node would like to do any internal processing, such as setting up geometry, then go for it now.

Specified by:

setupFinished in interface VRMLNodeType

Overrides:

setupFinished in class BaseGeoLOD

notifyExternProtoLoaded

public void notifyExternProtoLoaded(int index,
 VRMLNodeType node)

Description copied from interface: VRMLNodeType

Notify a node that an ExternProto has resolved. This will verify the objects type and add it to the render sceneGraph.

Specified by:

notifyExternProtoLoaded in interface VRMLNodeType

Overrides:

notifyExternProtoLoaded in class AbstractNode

Parameters:

index - The field index

node - The node resolved

setContent

public void setContent(int index,
 String mimetype,
 Object content)
                throws IllegalArgumentException

Description copied from interface: VRMLMultiExternalNodeType

Set the content of this node to the given object. The object is then cast by the internal representation to the form it needs. This assumes at least some amount of intelligence on the part of the caller, but we also know that we should not pass something dumb to it when we can check what sort of content types it likes to handle. We assume the loader thread is operating in the same context as the one that created the node in the first place and thus knows the general types of items to pass through.

Specified by:

setContent in interface VRMLMultiExternalNodeType

Parameters:

index - The field index to set the content for

mimetype - The mime type of this object if known

content - The content of the object

Throws:

IllegalArgumentException - The content object is not supported

visibilityStateChange

public void visibilityStateChange(boolean visible,
 javax.vecmath.Point3f position,
 javax.vecmath.AxisAngle4f orientation,
 javax.vecmath.Matrix4f localPosition)

Invoked when the user enters or leaves an area.

Specified by:

visibilityStateChange in interface OGLVisibilityListener

Parameters:

visible - true when the user enters the area

position - The position of the user on entry/exit

orientation - The orientation of the user there

localPosition - The vworld transform object for the class that implemented this listener

viewPositionChanged

public void viewPositionChanged(javax.vecmath.Point3f position,
 javax.vecmath.AxisAngle4f orientation,
 javax.vecmath.Matrix4f localPosition)

Notification that the object is still visible, but that the viewer reference point has changed. Ignored for this implementation.

Specified by:

viewPositionChanged in interface OGLVisibilityListener

Parameters:

position - The new position of the user

orientation - The orientation of the user there

localPosition - The vworld transform object for the class that implemented this listener

updateNodeBoundsChanges

public void updateNodeBoundsChanges(Object src)

Notification that its safe to update the node now with any operations that could potentially effect the node's bounds.

Specified by:

updateNodeBoundsChanges in interface org.j3d.aviatrix3d.NodeUpdateListener

Parameters:

src - The node or Node Component that is to be updated.

updateNodeDataChanges

public void updateNodeDataChanges(Object src)

Notification that its safe to update the node now with any operations that only change the node's properties, but do not change the bounds.

Specified by:

updateNodeDataChanges in interface org.j3d.aviatrix3d.NodeUpdateListener

Parameters:

src - The node or Node Component that is to be updated.

clearChildren

protected void clearChildren()

Clear the child node list of all children - both VRML and OpenGL.

Overrides:

clearChildren in class BaseGroupingNode

originChanged

public void originChanged()

Notification that the origin has changed.

Specified by:

originChanged in interface OriginListener

Overrides:

originChanged in class BaseGeoLOD
