KiNG (Kinemage, Next Generation) is an interactive system for three-dimensional vector graphics. It supports a set of graphics primitives that make it suitable for many types of graphs, plots, and other illustrations; although its first use was to display macromolecular structures for biophysical research. KiNG builds on Mage, JavaMage, and the "kinemage" (kinetic image) concept to deliver a full-featured Java application with a user-friendly interface and integrated editing features. The KiNG jar file can be used within a web page as a Java applet or Java object to promote easy access to kinemages or coordinate files from a web browser.
