Constructor Details

OGLCollision

public OGLCollision()

Construct a new default instance.

OGLCollision

public OGLCollision(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.

Parameters:

node - The node to copy

Throws:

IllegalArgumentException - The node is not a Group node

Method Details

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 transformation matrix only once per frame.

Specified by:

allEventsComplete in interface FrameStateListener

Overrides:

allEventsComplete in class AbstractNode

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.

setCollide

protected void setCollide(boolean state)

Set the value of the collide field. Used to change the collision status.

Overrides:

setCollide in class BaseCollision

Parameters:

state - true if the collision is being set

getSceneGraphObject

public org.j3d.aviatrix3d.SceneGraphObject getSceneGraphObject()

Get the Java3D scene graph object representation of this node. This will need to be cast to the appropriate parent type when being used. This should never be called before setupFinished() is called.

Specified by:

getSceneGraphObject in interface OGLVRMLNode

Returns:

The OGL representation of this grouping node

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 BaseGroupingNode

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

clearChildren

protected void clearChildren()

Clear the child node list of all children - both VRML and Java3D.

Overrides:

clearChildren in class BaseGroupingNode

addChildNode

protected void addChildNode(VRMLNodeType node)
                     throws InvalidFieldValueException

Add a single child node to the list of available children. This auto matically deals with DEF/USE and adds links and branchgroups where appropriate. When nodes are null, we do not add them to the OGL representation, only to the vfChildren list.

Overrides:

addChildNode in class BaseGroupingNode

Parameters:

node - The node to view

Throws:

InvalidFieldValueException - This is a bindable node shared

removeChildNode

protected void removeChildNode(VRMLNodeType node)

Remove the given node from this grouping node. If the node is not a child of this node, the request is silently ignored.

Overrides:

removeChildNode in class BaseGroupingNode

Parameters:

node - The node to remove

setProxy

protected void setProxy(VRMLNodeType app)
                 throws InvalidFieldValueException

Set node content as replacement for proxy.

Overrides:

setProxy in class BaseCollision

Parameters:

app - The new proxy. null will act like delete

Throws:

InvalidFieldValueException - The node does not match the required type.
