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.
GIMP is the GNU Image Manipulation Program. It is a freely distributed piece of software suitable for such tasks as photo retouching, image composition and image authoring. It can be used as a simple paint program, an expert quality photo retouching program, an online batch processing system, a mass production image renderer, a image format converter, etc.
Asymptote is a powerful descriptive 2D and 3D vector graphics language for technical drawing, inspired by MetaPost but with an improved C++-like syntax. It provides for figures the same high-quality level of typesetting that LaTeX does for scientific text. Asymptote is a programming language as opposed to just a graphics program. It can exploit the best features of script (command-driven) and graphical user interface (GUI) methods. High-level graphics commands are implemented in the language itself, allowing them to be easily tailored to specific applications.
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.
bed is an adjustable data format binary editor. Data formats are ASCII, unsigned and signed integers, float, bit-flags, bit-fields, labels, EBCDIC, and time_t. Different sizes and byte orderings are possible. Data types can be used in structures. Other data formats, filters, and procedures can be defined in plugins. It features copy, paste, undo, redo, search, replace, marks, record/play, and context sensitive help. bed can be used to edit raw hard drives. Under Linux and FreeBSD it is even usable without the X Window System.
Kid3 tagger can edit the ID3v1 tags and all ID3v2 frames in MP3 files and the tags in Ogg/Vorbis and FLAC files in an efficient way. It is easy to convert between ID3v1 and ID3v2, set the tags of multiple files to the same values and generate the tags from the file name or vice versa. Import is possible from freedb.org, MusicBrainz, and other sources of track data.
