Current Graphical User Interface toolkits like Swing are powerful, generic and portable, but cannot be used for some generic application classes such as graph editors, requiring programmers to use lower-level APIs such as Java2D which are more expressive but harder to use. ZVTM is a Zoomable User Interface (ZUI) toolkit implemented in Java , designed to ease the task of creating complex visual editors in which large amounts of objects have to be displayed, or which contain complex geometrical shapes that need to be animated. It is based on the metaphor of universes that can be observed through smart movable/zoomable cameras, and offers features such as perceptual continuity in object animations and camera movements, which should make the end-user's overall experience more pleasing.
