ZVTM is a Zoomable User Interface (ZUI) toolkit, 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 features a graphical object model that makes the task of creating, modifying, and animating graphical entities easier, and allows the definition of custom shapes, all through a simple API. It also features smooth zooming capabilities (2.5D/ zoomable user interface), multiple independent layers inside a single viewport, multi-threaded views, and support for exporting SVG documents.
