LIBSVM is an integrated software for support vector classification, regression, and distribution estimation. It supports multi-class classification. The goal is to help users from other fields to easily use SVM as a tool. LIBSVM provides a simple interface where users can easily link it with their own programs. It is implemented in both C++ and Java. A Python interface and a GUI demonstrating SVM classification and regression are also included in the package.
libtcp++ allows you to create C++ TCP/IP clients and servers without having to worry about gethostbyname, sockect, connect, bind, listen and accept. It has three classes, TcpClient , TcpServer and TcpIpRuleSet. TcpClient allows you to initiate TCP/IP connections, TcpServer is an abstract class to be used for creating servers by inheriting from it, and TcpIpRuleSet allows you to establish a set of IP-based access rules, and check IPs against them.
libxmi is a standalone C library for rasterizing 2-D vector graphics primitives such as wide polygonal lines, circular and elliptic arcs, and filled polygons. It's based on the vector graphics code in most X Window System servers. Some rendering extensions have been added, such as support for multicolored dashing patterns. Despite its origins, libxmi is completely decoupled from X11. It draws vector graphics onto a user-supplied matrix of pixels, not onto an on-screen window. It uses its own two-stage graphics pipeline.
The Lightflow Rendering Tools are a set of tools for advanced photorealistic rendering, aimed both at scientific visualization and artistic or cinematographic animation. Their features include: radiosity, caustics, volumetric rendering, hypertexturing, real displacement mapping, and NURBS. An extension to the Python language that integrates the Lightflow Rendering Tools in a simple scripting environment is available for free as a demo of the future releases.
