摘要
布料模擬,從以前到現在已經有非常多的學者,做了很多相關方面的研究,不論是以提出的布料的模型架構,或者是以動力學的計算方法,碰撞的偵測以及解決方法,都有著相當多的研究,有著非常豐富的成果。

由於電腦運算速度的快速提昇以及電腦遊戲與動畫的持續發展,應用在3D領域的電腦繪圖也愈來愈重要, 用GPU做一些電腦繪圖相關的應用,已經成為了一項主要的趨勢,而且發展的速度愈來愈快,運用的功能也愈來愈強大。

本篇研究主要提出一種基於物理模型的即時動態旗幟的模擬運動,在以往的研究中,人們提出了許多模擬布料運動的方法,這些方法的一個主要缺點是複雜度高、計算效率低,無法滿足交互設計和即時動畫的要求。本文提出的方法根據布料的物理特性,採用質點-彈簧系統在不增加質點數目的要求下,已近似的隱式積分法大量簡化系統的計算,並以風速和方向的控制技巧,可以即時地模擬旗幟在空中受到外力影響時的飄動的現象與行為,以滿足3D遊戲即時動畫的視覺效果。

關鍵字 : 布料動態模擬、布料、3D動畫、質點-彈簧、旗幟
Summary
Cloth simulation, there were a lot of scholars to now from in the past, has done the research of a lot of relevant respects, no matter with the model structure of the cloth that is put forward, or with the dynamics computing technology, the ones that collided detected examining and solution, there is quite a lot of research, there are very abundant achievements.

Because the fast promotion of the operation tempo of the computer and sustainable development of computer game and cartoon, it is more and more important in drawing to use the computer in the field of 3D, the application making some computer drawing with GPU and is correlated with, having already become a main trend, and the speed of development is faster and faster, the function used is stronger and stronger.

This page studies and proposes a kind of simulation based on instant dynamic flag of the physical model mainly, in past research, people have proposed a lot of methods of simulation cloth movement, a main shortcoming of these methods is that the complexity is high, computational efficiency is low, it is unable to respond to the request that design mutually with the instant cartoon. The method that this text puts forward adopts the particle- the spring system under increasing the quality to count the request for the item according to the physical characteristic of the cloth, the calculation of already approximate implicit a large number of reduced systems of total mark law, and with the control skill of wind speed and direction, can immediately simulation flag phenomenon and behavior of waving when influenced by the external force in the sky , in order to satisfy the visual effect of the 3D game instant cartoon.

Key word : Dynamic simulation of the cloth, cloth, 3D cartoon, particle- the spring , flag
