Class MouseZoom

  • public class MouseZoom
extends MouseBehavior
    MouseZoom is a Java3D behavior object that lets users control the Z axis translation of an object via a mouse drag motion with the second mouse button. See MouseRotate for similar usage info. Also this: < id = event[i].getID(); < if ((id == MouseEvent.MOUSE_DRAGGED) && < ((MouseEvent)event[i]).isAltDown() && < !((MouseEvent)event[i]).isMetaDown()){ > id = event[i].getID(); > if ((id == MouseEvent.MOUSE_DRAGGED) && > ((MouseEvent)event[i]).isAltDown() && > ((MouseEvent)event[i]).isMetaDown()){ 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 the middle button and not the right button is pressed. The new if statement says if the mouse is dragged and the middle button and the right button are both pressed. Added condition for the mouse pressed Added the ability to zoom based on user rotations and positions

    • Constructor Detail

      • MouseZoom

        public MouseZoom()
        Creates a default mouse zoom behavior.

      • MouseZoom

        public MouseZoom​(javax.media.j3d.TransformGroup transformGroup)
        Creates a zoom behavior given the transform group.
        Parameters:
        transformGroup - The transformGroup to operate on.

      • MouseZoom

        public MouseZoom​(int flags)
        Creates a zoom behavior. Note that this behavior still needs a transform group to work on (use setTransformGroup(tg)) and the transform group must add this behavior.
        Parameters:
        flags - DOCUMENT ME!

      • MouseZoom

        public MouseZoom​(int flags,
                 boolean behaviorfix)
        Same as above but with boolean fix.
        Parameters:
        flags - DOCUMENT ME!
        behaviorfix - DOCUMENT ME!

      • MouseZoom

        public MouseZoom​(int flags,
                 javax.media.j3d.TransformGroup VPTG,
                 boolean behaviorfix)
        Same as above but with Viewer Transform Group and boolean fix.
        Parameters:
        flags - DOCUMENT ME!
        VPTG - DOCUMENT ME!
        behaviorfix - DOCUMENT ME!
