public class PickZoomBehavior
extends PickMouseBehavior
implements MouseBehaviorCallback

A mouse behavior that allows user to pick and zoom scene graph objects. Common usage: 1. Create your scene graph. 2. Create this behavior with the root and canvas. See PickRotateBehavior for more details.

Constructor Detail

PickZoomBehavior

public PickZoomBehavior(BranchGroup root,
                        Canvas3D canvas,
                        Bounds bounds)
Creates a pick/zoom behavior that waits for user mouse events for the scene graph. This method has its pickMode set to BOUNDS picking.
Parameters:
root - Root of your scene graph.
canvas - Java 3D drawing canvas.
bounds - Bounds of your scene.

PickZoomBehavior

public PickZoomBehavior(BranchGroup root,
                        Canvas3D canvas,
                        Bounds bounds,
                        int pickMode)
Creates a pick/zoom behavior that waits for user mouse events for the scene graph.
Parameters:
root - Root of your scene graph.
canvas - Java 3D drawing canvas.
bounds - Bounds of your scene.
pickMode - specifys PickObject.USE_BOUNDS or PickObject.USE_GEOMETRY. Note: If pickMode is set to PickObject.USE_GEOMETRY, all geometry object in the scene graph that allows pickable must have its ALLOW_INTERSECT bit set.
Method Detail

setPickMode

public void setPickMode(int pickMode)
Sets the pickMode component of this PickZoomBehavior to the value of the passed pickMode.
Parameters:
pickMode - the pickMode to be copied.

getPickMode

public int getPickMode()
Return the pickMode component of this PickZoomBehavior.

updateScene

public void updateScene(int xpos,
                        int ypos)
Update the scene to manipulate any nodes. This is not meant to be called by users. Behavior automatically calls this. You can call this only if you know what you are doing.
Overrides:
updateScene in class PickMouseBehavior
Parameters:
xpos - Current mouse X pos.
ypos - Current mouse Y pos.

transformChanged

public void transformChanged(int type,
                             Transform3D transform)
Callback method from MouseZoom This is used when the Picking callback is enabled
Specified by:
transformChanged in interface MouseBehaviorCallback
Tags copied from interface: MouseBehaviorCallback
Parameters:
type - will be one of ROTATE, TRANSLATE or ZOOM

setupCallback

public void setupCallback(PickingCallback callback)
Register the class @param callback to be called each time the picked object moves
