Blender is a free 3D animation studio. It includes tools for modeling, sculpting, texturing (painting, node-based shader materials, or UV mapped), UV mapping, rigging and constraints, weight painting, particle systems, simulation (fluids, physics, and soft body dynamics and an external crowd simulator), rendering, node-based compositing, and non linear video editing, as well as an integrated game engine for real-time interactive 3D, and game creation and playback with cross-platform compatibility.
The Java Algebra System (JAS) is an object oriented, type safe, multi-threaded approach to computer algebra. JAS provides a well designed software library using generic types for algebraic computations implemented in the Java programming language. The library can be used as any other Java software package, or it can be used interactively or interpreted through a Jython or JRuby front end. The focus at the moment is on commutative and solvable polynomials, power-series, multivariate polynomial factorization, Gröbner bases, and applications.
wview is an application that controls a supported weather station to retrieve archive records and current conditions. Archive records may optionally be stored in a relational database (MySQL or PostgreSQL). At a user-defined interval, wview will use the archive history and current conditions to generate weather images (buckets and graphs) and Web pages based on configurable HTML templates. It supports serial and USB data loggers, as well as connectivity with a terminal server or serial server via TCP sockets.
Armadillo is a C++ linear algebra library (matrix maths) aiming towards a good balance between speed and ease of use. The API is deliberately similar to Matlab's. Integer, floating point, and complex numbers are supported, as well as a subset of trigonometric and statistics functions. Various matrix decompositions are provided through optional integration with LAPACK and ATLAS numerics libraries. A delayed evaluation approach, based on template meta-programming, is used (during compile time) to combine several operations into one and reduce or eliminate the need for temporaries.
nut is nutrition software to record what you eat and analyze your meals for nutrient composition. The database included is the latest USDA Nutrient Database for Standard Reference. This database contains values for vitamins, minerals, fats, calories, protein, carbohydrates, fiber, etc., and includes the essential polyunsaturated fats, Omega-3 and Omega-6. Nutrient levels are expressed as a percentage of the Daily Value, the familiar standard of food labeling in the United States, but also can be fully customized. Foods can be added from recipes or food labels, and nutrient intake can be graphed. The program is completely menu-driven and there are no commands to learn.
Wandora is a general purpose data extraction, management, and publishing application based on Topic Maps and Java. Wandora has a graphical user interface, layered presentation of knowledge, several data storage options, rich data extraction, import and export capabilities, and an embedded HTTP server that enables dynamic publication of Topic Maps. Wandora is well suited for rapid ontology construction and knowledge mashups.
