The Viewer object consists of: <UL> <LI>Physical Objects</LI> <UL> <LI>Canvas3D's - used to render with.</LI> <LI>PhysicalEnvironment - holds characteristics of the hardware platform being used to render on.</LI> <LI>PhysicalBody - holds the physical characteristics and personal preferences of the person who will be viewing the Java 3D universe.</LI> </UL> <LI>Virtual Objects</LI> <UL> <LI>View - the Java 3D View object.</LI> <LI>ViewerAvatar - the geometry that is used by Java 3D to represent the person viewing the Java 3D universe.</LI> </UL> </UL> If the Viewer object is created without any Canvas3D's, or indirectly through a configuration file, it will create the Canvas3D's as needed. The default Viewer creates one Canvas3D. If the Viewer object creates the Canvas3D's, it will also create a JPanel and JFrame for each Canvas3D. Dynamic video resize is a new feature in Java 3D 1.3.1. This feature provides a means for doing swap synchronous resizing of the area that is to be magnified (or passed through) to the output video resolution. This functionality allows an application to draw into a smaller viewport in the framebuffer in order to reduce the time spent doing pixel fill. The reduced size viewport is then magnified up to the video output resolution using the SUN_video_resize extension. This extension is only implemented in XVR-4000 and later hardware with back end video out resizing capability. If video size compensation is enable, the line widths, point sizes and pixel operations will be scaled internally with the resize factor to approximately compensate for video resizing. The location of the pixel ( x, y ) in the resized framebuffer = ( floor( x * factor + 0.5 ), floor( y * factor + 0.5 ) ) <p><P><P><DL><DT><B>See Also:</B><DD><A
