| dc.description.abstract | 近幾年來，線上電玩遊戲越來越受到歡迎。動畫的真實度以及計算效率為影響線上電玩效能的兩個重要尺度。此篇論文提出一個控制架構去驗證線上三維電玩的即時效能。此外，當有很多玩家同時在一個連線系統的時候，一個能夠維持資料傳輸量的想法也將被提出。精細度層級(LOD)調整的觀念將被用來處理線上互動遊戲效能的問題。精細度層級(LOD)的觀念被使用在處理動畫的觀感用來減少計算量並且維持動畫的真實度。再者，利用精細度層級(LOD)觀念的差值方法也被用來減少在線上互動電玩系統資料量的傳遞。最後，幾個實驗的場景將會在本篇論文中列出。 | zh_TW |
| dc.description.abstract | In recent years, on-line video games are more and more popular. The reality and the computational efficiency of the animation are two main criteria affecting the performance of such an on-line video game system. This thesis presents an architecture and a control algorithm for guaranteeing the real-time performance of simulating 3D animation in an on-line interactive multiplayer environment. Furthermore, an idea of maintaining the data transmission over the Internet is also proposed when there are numerous users connecting to the interactive game system. The concept of level of detail (LOD) is the key factor in the proposed on-line interactive game environment. The LOD concept is used for controlling the visualization of the animation and then reducing the computational cost and maintaining the reality of the environment. Moreover, the LOD concept is also applied at the interpolation stage of the environment for reducing the amount of data needed for the transmission in an on-line interactive game system. Finally, several scenarios of illustrative animations are presented in this thesis. | en |
