CGAL, the Computational Geometry Algorithms Library, is a large C++ library of geometric data structures and algorithms such as Delaunay triangulations, mesh generation, Boolean operations on polygons, and various geometry processing algorithms. CGAL is used in various areas: computer graphics, scientific visualization, computer aided design and modeling, geographic information systems, molecular biology, medical imaging, robotics and motion planning, and numerical methods.
AzureGE is a multi-platform OpenGL and OpenAL-based game engine. It has built-in support for I/O, threading, and networking, a particle system, a material generator, a texture generator, and a mesh/terrain generator. It is intended mainly for creating role playing games, but can also be used for other types of game.
Herqq UPnP (HUPnP) is a software library for building UPnP devices and control points conforming to the UPnP Device Architecture version 1.1. It is designed to be simple to use and robust in operation. It is built using the Qt framework, following many of the design principles and programming practices used in the Qt framework. It integrates into Qt-based software smoothly and enables truly rapid UPnP development.
The eXtensible Binary Universal Protocol (XBUP) project is an attempt to design a general binary communication protocol and file format. It is based on the unlimited unary-binary encoding and strongly typed block tree structure. It will provide a catalog service and processing infrastructure.
