Gcmc is a front-end language for generating G-code, SVG, and DXF for CNC mills, lathes, laser cutters, and other numerically controlled machines employing G-code, SVG, or DXF. The language is a context-free grammar created to overcome the archaic format of G-code programming, but can be used more generally for many targets. Gcmc aims to be more readable and understandable than G-code and enable programmatic designing. Gcmc makes extensive use of vector mathematics to support the 3D nature of CNC machining. It handles units as millimeters, mils (inch), degrees, and radians and performs automatic conversions where necessary.
OpenLink Virtuoso is a scalable, high-performance SQL-200n compliant object-relational database engine. It provide sophisticated database management for SQL, XML, and RDF. All interaction with Virtuoso occurs via its support of industry standard query languages, protocols, APIs, and data formats such as: ODBC, JDBC, OLE-DB, ADO.NET, XMLA, SQL, SPARQL, XQuery, SOAP, HTTP, WebDAV, SyncML, Atom (Publishing and Syndication), RSS, RDF, and more.
libdeco-ostc provides a library for dive decompression calculation. The library functions perform dive simulation using OSTC dive computer firmware and return decompression schedule information. The decompression model used is Buhlmann (ZH-L16C) with Gradient Factors. A C API (libdeco library) and Python API (DecoMecha module) are supported.
cvs-fast-export analyzes a collection of RCS files in a CVS repository (or outside of one) and, when possible, emits an equivalent history in the form of a fast-import stream. Not all possible histories can be rendered this way, and the program tries to emit useful warnings when it can't. The program can also produce a visualization of the resulting commit DAG in the DOT format handled by the graphviz suite.
LiVES is a simple to use yet powerful video effects, editing, conversion, and playback system aimed at the digital video artist and VJ. It runs under Linux, BSD, Mac OS X/Darwin, IRIX, and openMosix. It is frame and sample accurate, can handle almost all types of video, and is fully extendable through plugins and the included plugin builder tool. It can also be controlled remotely using OSC.
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.
