| dc.description.abstract | 目前和動作模擬相關論文中，主要討論人在陸地上之動作，原因在於人在水中的模擬，需將流體力學納入考量，因此物理模擬的部份會變得較為複雜。本研究希望提出一個較為簡單的方式來模擬整個游泳的過程。先用簡化的人體模型編輯出一序列的游泳動作，並將模型各部位轉換成同體積的球體，接著計算出重力、浮力、阻力和推力，並將這些力，作用於模型上，產生位移和轉動，便能模擬出人在水中游動時的動畫，最後再加上即時產生的水波，使整個結果更趨逼真。 | zh_TW |
| dc.description.abstract | The papers about human action simulation mainly focus on the action taking place on the land because it gets much harder to take fluid dynamics into account when the simulation happens in the water. Our work is expected to propose a simpler approach to simulate the human swimming. First, we use a simplified human model and edit a sequence of swimming action. Then we transform each part of the model into a sphere with the same volume, which makes it easier for our calculation. By this way, we attain the force of weight, buoyancy, drag, and thrust. These forces act on the model, which make the model move and rotate, so we have the simulation of human swimming. At last, real-time generated wave is added into our simulation to make it looks more real. | en |
