Design and optimization of a web 3D Massively Multiplayer Online Game engine

The biggest problem in transforming C/S MMOGs (Massively Multiplayer Online Games) into web games is how to load the game resources fluently without waiting for downloading during game time. Thus we propose following methods: 1) Reduce the response time of game resource server by using a shared memory database to buffer and manage the game resources; 2) Improve game resource download speed by cutting game resource into fixed-size fragments and transmitting them with UDP instead of HTTP; 3) Reduce waiting time in client by progressively loading and rendering. To optimize game performance and effects in clients, we adopt classical graphics libraries to render in browser using plugin techniques. To optimize the performance of service program in MMOG servers, we avoid using sync tools (e.g. semaphores) to save CPU cycles. Overall, we optimize the key points that limit the performance of web 3D game engines in both client and server.
