OPEN SOURCE PROJECTS
IM Framework
Project Owner, 100% contribution
A cross platform networking library. It is named Instant Mess aging Framework, but not limited to IM. Many
network protocols can be used as backend, and the framework will select the most proper one to use. The
framework provides some very simple interface classes that make network programming never so easy.

A 3D spirit library. It comes with a full function 3D spirit designer where you can turn a set of part models
into a spirit, and enable it with poses and actions. A set of interface classes are also implemented for it to be
used in C++ projects.

2D Mee
Project Owner, 90% contribution
2D version of the spirit library. Similarly it has a full function 2D spirit designer, with which you can design
faces, poses, and actions for a spirit. It can produce simple raster and vector images, as well as complex
spirit pack that you can use in your applications.
