Jmol

Jmol is an open-source Java viewer for chemical structures in 3D, that does not require 3D acceleration plugins. Jmol returns a 3D representation of a molecule that may be used as a teaching tool, or for research e.g. in chemistry and biochemistry. It is free and open source software, written in Java and so it runs on Windows, Mac OS X, Linux and Unix systems. There is a standalone application and a development tool kit that can be integrated into other Java applications, such as Bioclipse and Taverna.
