3Delight is a very fast RenderMan-compliant renderer designed to produce photorealistic images for serious production environments. Some of its features include ray tracing, global illumination, motion blur, depth of field, subdivision surfaces, programmable shaders, quality antialiasing, and antialiased multi-depth shadow maps. The API and the shading language are very similar to what is described in the RenderMan interface documentation.
Allegro is a multi-platform game library for C/C++ developers that provides many functions for graphics, sounds, player input (keyboard, mouse, and joystick), and timers. It also provides fixed and floating point mathematical functions, 3D functions, file management functions, compressed datafile, and a GUI.
GNU Aspell is a spell checker designed to eventually replace Ispell. It can either be used as a library or as an independent spell checker. Its main feature is that it does a superior job of suggesting possible replacements for a misspelled word than just about any other spell checker out there for the English language. Unlike Ispell, Aspell can also easily check documents in UTF-8 without having to use a special dictionary. Aspell will also do its best to respect the current locale setting. Other advantages over Ispell include support for using multiple dictionaries at once and intelligently handling personal dictionaries when more than one Aspell process is open at once.
Athene is a desktop system for Linux that uses its own graphics drivers for high speed access to your graphics card. Because the Athene desktop and its applications have direct access to the graphics hardware, they have a significant speed advantage over conventional X applications. Athene is also backwards compatible with your existing X11 software. It features a highly responsive interface, scalable icons, translucency, alpha blending, Unicode support, and Windows compatibility.
AxY FTP (formerly known as WXftp) is an easy-to-use FTP client for the X Window System. Features include an intuitive user interface (Motif and GTK+), side-by-side local and remote directory listings, simple and convenient session manager, on-line help, progress bar, passive and non-passive transfers, and more.
Behemot Graphics Editor is a graphics program which allows you to model and render 3D objects and scenes. It can create and graphically modify b-rep, blob, NURBS models. It can also logically intersect or subtract objects, render text into solid objects, edit polyline and NURBS curves, build rotation and sweep solids and link objects into groups for easy movement. Complex animations and advanced modelling operations can be realized Prolog scripts. Customizable vector fields allow you to deform the model. It can export scenes in DXF or VRML format or animation in MPEG format, and import some DXF and 3DS files.
bigloo-lib is a set of libraries for Bigloo, the Scheme programming language compiler. Most of the libraries are interfaces for various C libraries, such as the C runtime library, Gtk++, the LDAP client API, or the XML parser API. Other libraries are written entirely in pure Scheme, such as the HTTP library and the NODE library. The libraries are intended to make it easier to write programs in Bigloo scheme. bigloo-lib also provides a suitable framework to configure, compile, install, and deploy Bigloo libraries.
