All Implemented Interfaces:

MouseBehaviorCallback

public class PickRotateBehavior
extends PickMouseBehavior
implements MouseBehaviorCallback

A mouse behavior that allows user to pick and drag scene graph objects. Common usage:

1. Create your scene graph.

2. Create this behavior with root and canvas.

        PickRotateBehavior behavior = new PickRotateBehavior(canvas, root, bounds);
      root.addChild(behavior);
 

The above behavior will monitor for any picking events on the scene graph (below root node) and handle mouse drags on pick hits. Note the root node can also be a subgraph node of the scene graph (rather than the topmost).

Constructor Detail

PickRotateBehavior

public PickRotateBehavior(org.jogamp.java3d.BranchGroup root,
                          org.jogamp.java3d.Canvas3D canvas,
                          org.jogamp.java3d.Bounds bounds)

Creates a pick/rotate 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.

PickRotateBehavior

public PickRotateBehavior(org.jogamp.java3d.BranchGroup root,
                          org.jogamp.java3d.Canvas3D canvas,
                          org.jogamp.java3d.Bounds bounds,
                          int pickMode)

Creates a pick/rotate 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 PickTool.BOUNDS, PickTool.GEOMETRY or PickTool.GEOMETRY_INTERSECT_INFO.

PickTool.setMode(int)

Method Detail

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.

Specified by:

updateScene in class PickMouseBehavior

Parameters:

xpos - Current mouse X pos.

ypos - Current mouse Y pos.

transformChanged

public void transformChanged(int type,
                             org.jogamp.java3d.Transform3D transform)

Callback method from MouseRotate This is used when the Picking callback is enabled

Specified by:

transformChanged in 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
