white_dune is a graphical VRML97/X3DV editor, simple NURBS/Superformula 3D modeller, animation tool, and VRML97/X3DV commandline compiler in development. VRML97 (Virtual Reality Modeling Language) is the ISO standard for displaying 3D data over the Web via browser plugins ("HTML for realtime 3D"). X3DV is the direct successor of VRML97. VRML97 and X3DV have support for animation, real-time interaction, and multimedia (images, movies, and sounds). white_dune can read, create, and display VRML97/X3DV files and let the user change the scenegraph/fields. It also has support for stereoscopic view via "quadbuffer"-capable stereo visuals, and support for 3D input devices like a joystick, spaceball, or magnetic tracker.

Calc is arbitrary precision arithmetic system that uses a C-like language. It's useful as a calculator, an algorithm prototype, and as a mathematical research tool. More importantly, calc provides a machine-independent means of computation. Calc comes with a rich set of builtin mathematical and programmatic functions.

SaVi is satellite visualization software that lets you create, run, examine, and modify satellite orbits in two and three dimensions. Simulations of Iridium, Globalstar, Galileo, GPS, and other satellite constellations are included. SaVi requires Tcl and Tk on a system with Unix libraries. SaVi works well with the 3D renderer Geomview. Geomview is optional, though recommended for its 3D rendering capabilities.

VisIt is an interactive parallel visualization and graphical analysis tool for viewing scientific data. Users can quickly generate visualizations from their data, animate them through time, manipulate them, and save the resulting images for presentations. VisIt contains a rich set of visualization features so that you can view your data in a variety of ways. It can be used to visualize scalar and vector fields defined on two- and three-dimensional (2D and 3D) structured and unstructured meshes. It was designed to interactively handle very large data set sizes in the terascale range, and works well down to small data sets in the kilobyte range.

TacitPixel (formerly libTAP ) is a prototyping system for virtual reality and augmented reality applications. It runs on a variety of platforms. RAP (rapid application prototyping) is done through the Lua interface, which mirrors the C++ namespace as closely as possible. libTAP has a small but distinctive feature set, focused on prototyping of realtime 3D simulations.

OpenEXR is a high dynamic range (HDR) image file format developed by Industrial Light & Magic for use in computer imaging applications. It includes support for 16-bit floating-point pixels (compatible with NVIDIA's Cg shader language "half" datatype), several lossless compression algorithms, and extensible image metadata attributes.

BLAST is a set of similarity search programs designed to explore all of the available sequence databases regardless of whether the query is protein or DNA. It uses a heuristic algorithm which seeks local as opposed to global alignments, and is therefore able to detect relationships among sequences which share only isolated regions of similarity. It can be run locally as a full executable, and can be used to run BLAST searches against private, local databases, or downloaded copies of the NCBI databases. It runs on Mac OS, Win32, LINUX, Solaris, IBM AIX, SGI, Compaq OSF, and HP- UX systems.
