LiquidMaya is a Maya to Renderman plug-in that handles full Renderman output support with a focus on speed, efficiency, and extensibility. Its features include procedural rib generation, full network rendering support, segmented rib files, a shader assignment interface, and much more. Along with the ability to write full C++ plug-ins, it is incredibly easy to script Liquid with Mel. Liquid was used for the visual effects of the "Lord of the Rings" movie.
Lush is a Lisp dialect with extensions for object-oriented and array-oriented programming. It is intended as a programming environment for prototyping numerically intensive applications. Unlike alternatives like Python or SciLab, Lush is designed for easy integration of existing C/C++/Fortran codes.
Fityk is nonlinear curve-fitting and data analysis software. It allows data visualization, separation of overlapping peaks, and least squares fitting using standard Levenberg-Marquardt algorithm, a genetic algorithm, or Nelder-Mead simplex method. It knows about many functions (mostly bell-shaped, like Gaussian, Loretzian, Pearson 7, Voigt, Pseudo-Voigt, and Doniach-Sunjic) and user-defined functions can be easily added. It also enables background subtracting, data calibration, and task automation with a simple script language. It is mainly used to analyze powder diffraction patterns, chromatography, photoluminescence, infrared, and Raman spectroscopy, but it can be used to fit analytical functions to any kind of data.
IT++ is a C++ library of mathematical, signal processing, and communication classes and functions. Its main use is in simulation of communication systems or for performing research in the area of communications. The kernel of the library consists of generic vector and matrix classes and lots of functions for vectors and matrices. Such a kernel makes the IT++ library similar to MATLAB or GNU Octave.
breve is a 3D simulation environment designed for the simulation of decentralized systems and artificial life. While the concept is similar to existing packages such as Swarm and StarLogo, the implementation, which simulates both continuous time and continuous 3D space, is quite different. It also includes an experimental physics engine, allowing the user to implement real-time physical simulations. Simulations are written in a simple object-oriented language called "steve". Users define an agent's behavior by specifying how the agent interacts with the world at each timestep and how the agent interacts when it collides with other agents. The ultimate goal of the system is to allow decentralized simulations to be implemented quickly and easily while providing a sophisticated set of object classes and libraries to facilitate the construction of advanced artificial life simulations.
GPSBabel converts waypoint data between about fifty file formats, including Magellan and Garmin serial, Garmin USB, Mapsource, Mapsend, Streets & Trips, Delorme, National Geographic, many PDA formats, and many others. It is endian and word-size safe, includes a GUI, and runs on a variety of operating systems. It also supports Groundspeak GPX extensions for geocaching.
Swiss-PdbViewer is an application that provides a user friendly interface for analyzing several proteins at the same time. The proteins can be superimposed in order to deduce structural alignments and to compare their active sites or any other relevant parts. Amino acid mutations, H- bonds, angles, and distances between atoms are easy to obtain with the intuitive graphic and menu interface.
OpenEXR is a high dynamic range (HDR) image file format developed by Industrial Light & Magic for use in computer imaging applications. It includes support for 16-bit floating-point pixels (compatible with NVIDIA's Cg shader language "half" datatype), several lossless compression algorithms, and extensible image metadata attributes.
Ikaros is a framework for writing and running component-based simulators. It is used for simulations of brain areas and learning models, but is general enough to be easily used for any discrete-time simulations. A simulation consists of modules written in C or C++ that are connected in the simulator, with connections specified in an XML file. It runs on the console, and can optionally generate a dynamic browser-based UI with SVG for graphics generation. There are also socket-based hooks for adding a full GUI. The package contains a number of modules and complete documentation for working with the framework.
