近年來，在電腦動畫、電玩、電視影集、或是電影中，聲勢浩大的群眾場面越來越常見。傳統使用關鍵格調整角色動作的方式過程繁雜沒有效率，藉由電腦動畫軟體中分子系統的模擬，可以有效的解決這些問題。
本研究以五種虛擬力為基礎，配合電腦動畫軟體中環境力場的設定，使用程式語言對群體中個體做進一步的操控。並進行虛擬力對個體影響的實驗，完成簡單的群體運動動畫，以驗證此構想的可行性。

It is getting more and more to see throng of people acting in one scene rencently in animation, video games, TV shows or movies. It is complicated and inefficient to use keyframe to adjust characters' movements. It could solve the problem with simulation of particle system in computer animation software.
This research is based on five virtual forces to control the specific individual in the crowd with programmed language and the setup of enviroment field in the animation software. I was experimenting with virtual force to influence the individual and completed a simple crowd simulation animation to identify my hypothesis.
