GRASS (the Geographic Resources Analysis Support System) is a software raster- and vector-based GIS (Geographic Information System), image processing system, graphics production system, and spatial modeling system. It contains many modules for raster data manipulation, vector data manipulation, rendering images on the monitor or paper, multispectral image geocoding and processing, point data management and general data management. It also has tools for interfacing with digitizers, scanners, and the PostgreSQL, DBF, and ODBC connected databases. GRASS operates on all common operating systems.
BALLView is an extensible viewer for bio-molecular structures. It provides all standard models and offers rich functionality for molecular modeling and simulation, including molecular mechanics methods (AMBER, CHARMM, and MMFF94 force fields), continuum electrostatics methods employing a Finite-Difference Poisson Boltzmann solver, secondary structure calculation, molecular editing and docking. Since BALLView is based on BALL (the Biochemical ALgorithms Library), it is easily extensible on the level of C++ code. In addition, it provides a Python interface with Integrated Development Environment features to allow interactive rapid prototyping.
Python Mesh Viewer is a very basic tool to display and play with 3D models. You can either construct them in the code (by defining points, triangles, and quads) or load them from a file. Currently, the only file format supported is the ".mesh" format from the closed source software medit. The rendering is done with absolutely no hardware acceleration (no OpenGL).
The Chemistry Development Kit (CDK) is a library of Java classes for chemo-, bioinformatics, computational chemistry, and chemometrics. It provides important algorithms like substructure search, SMILES, Gasteiger charges, QSAR descriptor calculation, 3D structure generation, 2D layout and rendering, many IO formats, atom typing, and more.
The Second Life Viewer is the client for logging into the Second Life 3-D virtual world, where residents explore, purchase virtual land, open businesses, build real estate, and create scripted objects such as cars, robots, or magic wands. Second Life residents retain full intellectual property rights for the digital content they create and upload, including avatar characters, clothing, scripts, textures, objects, and designs.
Raggier is a plugin-based raytracer that supports XML format scenefiles, POV-Ray, and Polyray scenefiles. Other facilities planned include Lindermayer Systems (L-Systems), AVI/OGM (Ogg Vorbis)/Matroska animations, and a Perl/PHP Web interface. Raggier uses the Libtrace library, modified with various fixes to get it to compile using gcc 3.x and to improve the results. The modified version is called LibTraceMod and is available in the CVS.
Julius MV1 is a showcase application for the Julius framework. It can be used as a fully functional DICOM 3.0 or RAW volume viewer as well as a viewer for large polymesh datasets. It also provides basic data processing features such as volume segmentation or polymesh decimation. Julius MV1 can be used as a basis and testbed for other applications developed with the Julius Framework. The Julius Framework (which comes bundled with MV1) is a general software architecture for medical visualization, simulation, and navigation.
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.
Mars MOLA Viewer displays a fly-over rendering of the Martian surface, as measured by the Mars Global Surveyor, in real-time 3D animation. It downloads the Mars Orbiting Laser Altimeter topographic data files and uses them to drive the rendering. The user controls the position and the angle of the camera, and can move seamlessly over the entire Martian surface from -88 to 88 degrees latitude. It is a Java Web Start program with 1-click installation from your browser (depending on platform/browser).
