BRL-CAD is a powerful constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, and image and signal-processing tools.
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.
The Internet Document And Report Server (IDRS) is a full Web development platform. All pages are built using an XML like dialect called the Reporting Markup Language (RML), can be generated using data from any JDBC complient database, and mostly require no programming logic. For reports that do require programming logic, RML pages can also use external Java classes and embedded JPython and BeanShell scripts for a higher level of control. Features of the IDRS include user-based security, data connection pooling for use by both the central IDRS system and by individual reports, and multiple databases to be used for each report and JSP.
PVM (Parallel Virtual Machine) is a portable message-passing programming system, designed to link separate host machines to form a ``virtual machine'' which is a single, manageable computing resource. The virtual machine can be composed of hosts of varying types, in physically remote locations. PVM applications can be composed of any number of separate processes, or components, written in a mixture of C, C++ and Fortran. The system is portable to a wide variety of architectures, including workstations, multiprocessors, supercomputers and PCs.
sml/nj (Standard ML of New Jersey) consists of a compiler, compilation manager, and libraries for Standard ML. Included are CML (Concurrent ML) and eXene (a toolkit for X based on CML). The compiler produces efficient code for most popular architectures (Intel x86, Sparc, Alpha, Mips, HP-PA, PowerPC) and runs under Unix, Linux, or Windows (95,98,NT).
The Snack sound extension adds commands for sound play/record and sound visualization, e.g. waveforms and spectrograms. It supports in- memory sound objects, file based audio, streaming audio, WAV, AU, AIFF, and MP3 file formats, synchronous and asynchronous playback. The visualization canvas item types update in real-time and can output postscript. New commands and file formats can be added using the Snack C-API.
The c-tree Plus embedded database engine offers developers several APIs that provide low-level routines, ISAM-level control, and higher-level interfaces. c-tree Plus is distributed in complete C source, has been ported to 100+ environments and includes a robust database Server SDK. It can be used to develop single user and peer-to-peer applications, or the client-side for applications using FairCom's database server, the c-tree Server.
GraphPak is a programming library of 2D and 3D charting objects for the Qt toolkit. It provides software developers with a set of C++ objects to easily create charts or graphs that aid in the visual presentation of technical and business data. This release includes Bar, Line, Pie, Ring, Area, Hi-Lo, Box and Whisker, and Polar charts. It is based on the KD Chart product from Klarälvdalens Datakonsult AB.
libGlass is a scalable set of components that can be used by applications to perform distributed computing. Applications are built by reusing the available components as needed. One of the major goals of Glass is to be a user-friendly framework, not only suitable for new applications, but also for legacy code. This is an important feature, as most available solutions for distributed computing require a substantial amount of rewrite of legacy code.
