Audiality is a highly scalable and portable audio engine and synthesizer. MIDI files are used in combination with scripting and modular synthesis, to minimize file sizes and maximize flexibility. Audiality can be used as a music and sound effects player in multimedia productions, or as a realtime MIDI synthesizer.
The Biochemical ALgorithms Library (BALL) is a framework for rapid application development in molecular modeling and structural bioinformatics. BALL provides an extensive set of data structures as well as classes for molecular mechanics, advanced solvation methods, comparison and analysis of protein structures, file import/export, NMR shift prediction, and visualization. Its extensibility results from an object-oriented and generic programming approach.
BALLView is an extensible viewer for bio-molecular structures. It provides all standard models and offers rich functionality for molecular modeling and simulation, including molecular mechanics methods (AMBER, CHARMM, and MMFF94 force fields), continuum electrostatics methods employing a Finite-Difference Poisson Boltzmann solver, secondary structure calculation, molecular editing and docking. Since BALLView is based on BALL (the Biochemical ALgorithms Library), it is easily extensible on the level of C++ code. In addition, it provides a Python interface with Integrated Development Environment features to allow interactive rapid prototyping.
BuDDy was created as part of a PhD project on model checking of finite state machines by Jørn Lind-Nielsen. The package has evolved from a simple introduction to Binary Decision Diagrams (BDDs) to a full blown BDD package with all the standard BDD operations, reordering, a C++ interface, and a wealth of documentation.
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.
Babel is an IDL-based language interoperability tool specific to engineering and scientific applications. It allows Fortran 77, Fortran 90, C, C++, Java, and Python to call each other in a single address space for maximum performance. Babel won a 2006 R&D 100 award from R&D Magazine.
Bambookit GUI is a completely XML-scriptable user interface to build real-time interactive Web application front-ends. Applications occupy 100 Kb of device memory and run on any Java-enabled browser. Users can move windows, resize containers, scroll and sort tables, lists, trees, see real-time data display, use a layout manager, and more. All rendering and event handling is managed in the XML scripts.
