OrbitBehavior "zooms" by translating the view platform closer to the object. With a parallel projection, distance to the object doesn't have any effect on the rendered size of the object. If you need a parallel projection zoom, you'll need to either find another behavior, modify OrbitBehavior, or write your own. Setting either the screen scale or the object scale would work; the screen scale is preferable because updating a view is less expensive than updating geometry. -- Mark Hood =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
