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.
K-3D is a 3D modeling, animation, and rendering system for GNU/Linux & Win32. Features include creation and editing of geometry in multiple realtime OpenGL solid, shaded, and texture-mapped views; unlimited undos and redos; complete extensibility at runtime through third-party plugins; animated procedural geometric effects; all parameters animatable through a consistent control-spline based interface; rendering pipeline to Renderman Interface compliant rendering engines; optimization for use with the Aqsis rendering engine, which features solid modelling, true displacement, and user programmable shaders; and support for background and batch rendering.
Verse is a network protocol and client/server application architecture for multiuser realtime distributed 3D graphics applications. It uses a lightweight server to store world data, and then relies on clients to connect and use the data in various ways. Verse uses subdivision surfaces as its single geometric primitive, which both conserves bandwidth and allows very good scalability and visual quality on modern 3D hardware.
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.
EZFB is a polymorphic, object oriented Linux frame buffer API written in C, designed to adapt at run time to control any properly configured Linux frame buffer video system. It offers independent, simultaneous control of multiple video cards within a single system, exceptional control of colors, the ability to display all or portions of bitmap files anywhere on the screen, automatic color depth conversion, the ability to capture to bitmap files, an 8x8 bitmapped font, routines to draw points, lines, outlined and filled rectangles, signal trapping for automatic screen clean-up at process termination, and much more. The demonstration applications include a bitmap viewer, screen capture utility, screen saver, and a touch screen calibration utility and an application for generating, viewing, transforming, and saving files according to The International Laser Display Association's ILDA file format.
Fandango is a GL-rendered, Python-scripted CAD program. The low-level functionality is programmed in C++, and then the relevant functions are exposed to Python and used as building blocks for more functions. Currently the memory core allows lines, triangles, line strips, and triangle strips. Texture, blending, and lighting can be switched on and off from a command line.
WireFusion allows interactive, plug-in free, and very compact Java presentations and product simulations to be created for the Web. Development involves visually connecting preprogrammed objects or by coding in Java. Several add-ons are available, including a real-time 3D engine where textures can be replaced with interactive 2D presentations, an MPEG video player, a slide show viewer, and an MP3 player.
Garbure is a collection of dedicated distributions. Each distribution provides carefully selected tools for a specific target domain, and is completed with examples and documentation. The set of distributions forms an entity, but each distribution works also on its own. All elements are arranged in the same way for each distribution.
Shader Maker is a simple, cross-platform GLSL editor. It provides the basics of a shader editor, such that students can get started with writing their own shaders as quickly as possible. This includes syntax highlighting in the GLSL editors, a geometry shader editor (as well as vertex and fragment shader editors, of course), interactive editing of the uniform variables, light source parameters, pre-defined simple shapes and a simple OBJ loader, and a few more.
