Method Details

observedNode

public void observedNode(org.j3d.aviatrix3d.SceneGraphObject parent,
 org.j3d.aviatrix3d.SceneGraphObject child,
 boolean shared,
 int depth)

Notification of a scene graph object that has been traversed in the scene.

Specified by:

observedNode in interface org.j3d.renderer.aviatrix3d.util.SceneGraphTraversalObserver

Parameters:

parent - The parent node of this node

child - The child node that is being observed

shared - true if the object reference has already been traversed and this is beyond the first reference

depth - The depth of traversal from the top of the tree. Starts at 0 for top.

updateNodeBoundsChanges

public void updateNodeBoundsChanges(Object src)

Specified by:

updateNodeBoundsChanges in interface org.j3d.aviatrix3d.NodeUpdateListener

updateNodeDataChanges

public void updateNodeDataChanges(Object src)

Specified by:

updateNodeDataChanges in interface org.j3d.aviatrix3d.NodeUpdateListener

run

public void run()

Flashes the node till the maximum is reached.

Specified by:

run in interface Runnable

setAlternateAppearance

public void setAlternateAppearance(org.j3d.aviatrix3d.Node n,
 org.j3d.aviatrix3d.Appearance app)

Set an alternate appearance to a node and its children. This class has memory for one alternate appearance. Multiple calls to this method will overwrite the previous values.

Parameters:

n - The node

app - The new appearance

restoreAlternateAppearance

public void restoreAlternateAppearance(org.j3d.aviatrix3d.Node n)

Restore the alternate appearance for a node.

Parameters:

n - The node

setShowOnlyAppearance

public void setShowOnlyAppearance(org.j3d.aviatrix3d.Node n,
 org.j3d.aviatrix3d.Appearance hiddenAlternateAppearance)

Set a show-only appearance to a node and its children. This class has memory for one alternate appearance. Multiple calls to this method will overwrite the previous values. TODO need to add method to SceneGraphTraversal to turn off other nodes when rendering.

Parameters:

n - The node

hiddenAlternateAppearance - The new appearance

restoreShowAllAppearance

public void restoreShowAllAppearance(org.j3d.aviatrix3d.Node n)

Restore the alternate appearance for all nodes. TODO need to add method to SceneGraphTraversal to restore other nodes when rendering.

Parameters:

n - The node

blink

public void blink(org.j3d.aviatrix3d.Node n,
 int numFlashes,
 int flashLength)

Blink a node and its children for a certain amount of time. Blinking is implemented with an alternate transparent appearance.

Parameters:

n - The node

numFlashes - The number of times to blink the node.

flashLength - The length in ms of a flash
