public class MouseRotate extends MouseBehavior
MouseRotate is a Java3D behavior object that lets users control the rotation of an object via a mouse.

To use this utility, first create a transform group that this rotate behavior will operate on. Then, 


     MouseRotate behavior = new MouseRotate();
     behavior.setTransformGroup(objTrans);
     objTrans.addChild(behavior);
     behavior.setSchedulingBounds(bounds);
The above code will add the rotate behavior to the transform group. The user can rotate any object attached to the objTrans. Also this: invalid input: '<' id = event[i].getID(); invalid input: '<' if ((id == MouseEvent.MOUSE_DRAGGED) invalid input: '&'invalid input: '&' invalid input: '<' !((MouseEvent)event[i]).isMetaDown() invalid input: '&'invalid input: '&' invalid input: '<' !((MouseEvent)event[i]).isAltDown()){ > id = event[i].getID(); > if ((id == MouseEvent.MOUSE_DRAGGED) invalid input: '&'invalid input: '&' > ((MouseEvent)event[i]).isMetaDown() invalid input: '&'invalid input: '&' > !((MouseEvent)event[i]).isAltDown()){ Note: By changing the bangs (!), you control which of the mouse buttons are filtered using the Alt and Meta key nomenclature. The old if statement says if the mouse is dragged and neither the right nor middle button are pressed . The new if statement says if the mouse is dragged and the right button and not the middle button is pressed. Made Additions under the mouse conditions for picking Added the algorithm to rotate the object by multiplying the inverse of the viewers rotation then applying the users rotation (just like when looking normal to XY plane) then multiply back in the original users rotation to put object back with the newly applied rotations.
