摘要
随着计算机图形技术的发展,布料动画成为3D游戏和动画电影相关领域研究者共同关心和研究的课题,并呈现蓬勃发展的趋势.布料动画的主要目标是表现布料丰富的运动细节,获得细腻、逼真的动画效果,可广泛应用于游戏、动画和虚拟现实等众多领域.论述了国内外基于物理仿真的布料动画建模的研究现状,总结了基于物理仿真的布料动画基本理论和方法.通过对近年来该领域相关文献的分析和归纳,发现其中存在的优缺点和相互间的联系,力图为3D游戏和动画中布料动画仿真技术的研究提供系统的思路.
With the development of computer graphics technologies, modeling and simulation of cloth animation becomes a common subject in 3D game and animated film related field, and presents the booming trend. The main objective of cloth animation is to obtain rich details of cloth movement and realistic animation. It can be widely used in games, animation and virtual reality, and many other fields. For its complicated nonlinear, anisotropic elastic behavior of the cloth, natural and realistic clothing wrinkles and shapes are difficult to create. The researches on cloth animation based on physical simulation are reviewed and the basic theory, method and framework are summarized. For the widely used methods in cloth animation, the essential process such as modeling, solving dynamics equations, collision detection and response are introduced. With analyzing the related literatures, the advantages, disadvantages and interrelationship of the existing modeling and simulation methods are summarized. Finally, from the demand of realistic performance and real-time interaction, future directions in modeling and simulation of cloth animation are discussed.
