Jmol is a Free, Open Source molecule viewer and editor. It is a collaboratively developed visualization and measurement tool for chemical scientists. Jmol is an active project, and there are new features being added to it on a daily basis. Users are encouraged to modify it to fit their needs and to contribute their changes to the project.
Ptplot is a set of Java classes that can be used as an applet or an application for graphing datasets. It reads PlotML, binary, or ASCII data, is autoranging, and automatically or manually labels axes and tick marks. It can plot live, animated plots and provides zooming. It also includes Bourne shell scripts and DOS .bat files that can be used as a replacement for xgraph, the X11 graphing tool.
WebCharts 3D allows you to deliver general purpose and specialized 2- and 3-dimensional charts as applets or interactive server-generated images (PNG, GIF, JPEG, SWF, SVG, PDF, TIFF, VML, CANVAS, and WBMP) to Web browsers and mobile devices, or embed charts into stand-alone Swing/SWT applications. It includes a WYSIWYG (What You See Is What You Get) designer that can be easily incorporated into your own applications to provide your end-users with chart editing capabilities. Full JSF and Sun Creator support and a free Eclipse Designer plugin are included.
JOGL is a reference implementation of the Java bindings for the OpenGL API, which is designed to provide hardware-supported 3D graphics. It provides full access to the APIs in the OpenGL 1.4 specification as well as nearly all vendor extensions, and integrates with the AWT and Swing widget sets.
The Magelan Graphics Editor is a simple 2D vector graphics editor with basic support for AutoCAD DXF files (both reading and writing). It features complete and easy control over each entity's properties and support for mouse gestures. The package also includes a compact Drawing/Editor API which can be used wherever 2D graphics modelling/editing is required.
FrAid (Fr[actal] Aid) is a programming language that is appropriate for mathematical computations, visualization, batch processing, and more. It features both a standalone application that provides a programming environment for the language and a system for integrating the language with Java. The Java interface allows mathematical equations and formulas to be used with Java code, making it easier to process numerical computations, symbolic computations, imaging, CAD, and more.
ProActive is a Java library for parallel, distributed, and concurrent computing as well as mobility and security in a uniform framework. It provides a comprehensive API and a graphical interface and is based on an Active Object pattern, a uniform way to encapsulate a remotely accessible object, a thread as an asynchronous activity, an actor with its own script, a server of incoming requests, a mobile and secure agent, and a component with server and client interfaces. It simplifies the programming of applications distributed over a LAN, clusters, an intranet, or Internet GRIDs.
