Graphics3D is a free, Open Source C++ library for game developers, researchers, and students. It is a base of robust and high performance code common to most 3D projects. It is not a standalone graphics or game engine--it is the set of pieces you need to jumpstart your own engine or graphics project. The library has two parts: G3D for pure math, and GLG3D for interacting with hardware acceleration via OpenGL. You can use G3D without GLG3D if you want to use another 3D API (like DirectX) or don't like the OpenGL abstraction.

C++ Regex Engine provides a robust regular expression library for use in C++. The syntax of the regular expression language is very close to the Perl 5 standard. The classes given somewhat mirror those found in Java's regular expression library, but have several improvements. The intended audience of this package is anyone who does a lot of data parsing (e.g. sysadmins), people tired of trying to decipher Perl scripts, and regular expression beginners who know C++. Some knowledge of the STL's vector and string will come in handy, but isn't necessary.

Java for C++ is a tool to generate C++ wrapper classes for existing Java classes. This tool reads a list of Java class names and creates source code for C++ classes to wrap them. The implementation of the wrapper classes uses JNI (Java Native Interface) to call the "real" Java classes. The C++ API to use these wrapper classes is very close to the API of the original Java classes. So developers of C++ software can use Java classes as if they have been implemented in C++.
