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.
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.
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.
libQGLViewer is a C++ library based on Qt that eases the creation of OpenGL 3D viewers. It provides some of the typical 3D viewer functionality, such as the ability to move the camera using the mouse, which is lacking in most of the other APIs. Other features include mouse manipulated frames, interpolated keyFrames, object selection, stereo display, screenshot saving, and much more. It can be used by OpenGL beginners as well as to create complex applications, being fully customizable and easy to extend. It ships with many examples and comprehensive documentation.
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).
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.
