   • Real-time doodle function makes chat here more funny. Users can draw something on the board, and the drawing could be seen by all the users in the same chat room once it happens. Each room has its own drawing board.
   • At the bottom of the drawing board, there are color-picker and clear-screen time notice, of which interval is decided by administrator. When time is up or the doodle data reaches very rate, it will be cleaned automatically.
   • Users can decide whether to show or hide drawing by click the switch icon on the left of the top.
4. Funny smiley, animations and backgrounds
   • There are various funny smiley and animations in the flash chat. They make your communication much more interesting and enjoyable than just words on the screen. Besides, the flash chat offers your many different backgrounds for you to enjoy. You will find one go perfect with your mood or the topic. Just enjoy!
5. Skin Change and Customization
   • Various interface styles are available for you to select. You can change the Chat skin as you like whenever needed. If you want a special one fitting to your web site, it is also supported that you design and custom the skin by yourself. Or you can ask to do it for you as required.
   • It can be only defined by exterior that which interface style can be used. Once you change the skin, it will be seen immediately by the your users entering later.
6. Multi-language Interface
   • Automatically detect users language system and load language package to carry out Multilanguage function. Users can decide what language to display on the Flash client by transferring exterior parameter to Flash SWF. All the interface language information will be preserved in the exterior XML file. Also users can add language package by dint of help file.
7. Users Management
   • All the information of every user, both registering and logging in as a guest, will be conserved by server in the form of file. Users may establish own advance message. Here the advance defined message is temporary, and it is only kept on the user computer.
   • The registered users are divided into three kinds: ordinary user, room administrator and general administrator.
8. Administering Module
   • The administrator has rights to keep someone and some dialogue unsuitable away from the chat room. Restricting the numbers of chat rooms, forbidding users logging and adding or reducing users are also included in administering module. And administrator can broadcast news to everyone online.
9. Chat History
   • The chat record is stored both in client and server terminals. When users log in, the latest chat record will be shared. The private chat record is also saved in client terminal and protected by Play.
   • Whether to save the chat history is depended on users decision. Since the computers for saving chat history are public ones, it is not safe to do that.
10. Multi-servers Support
    • CHAT supports many servers such as Adobe Flash Media Server or Red5, which can work under Windows, Linux, Unix, Solaris, FreeBSD, MacOSX and DEBIAN systems.
    • Cross-platform client does not need third-party plug-ins, as long as users browser installed Flash Player 8 or a higher.

The code is written entirely in C with an object-oriented approach based mostly on the design of GTK . Careful attention is paid to performance related issues as the initial goal of GTS is to provide a simple and efficient library to scientists dealing with 3D computational surface meshes.

Major Features:

1. Simple object-oriented structure giving easy access to topological properties.
2. 2D dynamic Delaunay and constrained Delaunay triangulations.
3. Robust geometric predicates (orientation, in circle) using fast adaptive floating point arithmetic
4. Robust set operations on surfaces (union, intersection, difference).
5. Surface refinement and coarsening (multiresolution models).
6. Dynamic view-independent continuous level-of-detail.
7. Preliminary support for view-dependent level-of-detail.
8. Bounding-boxes trees and Kd-trees for efficient point location and collision/intersection detection.
9. Graph operations: traversal, graph partitioning.
10. Metric operations (area, volume, curvature ...).
11. Triangle strips generation for fast rendering.
