基於物理模擬之物體表面運動重現

Abstract

電腦動畫的技術已經被使用了很長一段時間了，不管是在電影或是遊戲裡，我們都可以發現大量動畫的使用。然而，要做出一段很真實的動畫並不容易，在我們的論文裡，我們要模擬的是人體上比較柔軟的部分，這些部分通常比較難模擬。舉例來說，當一個有肚腩的人在跑步時，我們會希望看到肚子能有晃動，但是這部分的模擬十分難做。所以在我們的論文裡，我們利用每一個瞬間的動作來計算模型的力，再將力傳送到要模擬的部分來完成我們新的動畫，希望能讓舊的動畫更像真實的。

Computer animation technology has been used for a long time. In movie or games, we can easily find animation in the scene. However, making a animation looks real is not a easy job. In this thesis, we focus on the soft and flexible parts of the body. These parts are usually not easy to simulate. For example, when a big stomach man is running, his stomach should shake. But shaking is hard to simulate. So in this thesis we can refine the animation more real. In the thesis we calculated the forces between each frames and propagate the forces to the shaking parts. Then put the new frames into the animation to make the old animation more real.
