实时模拟弹性物体的行为是当前计算机图形学的目标之一。它的应用领域之一与虚拟现实有关，主要是在手术模拟系统中。在计算机图形学中，用于构造具有可变形行为的对象的模型称为可变形模型。这有两个相互冲突的特征：互动性和运动现实主义。迄今为止开发的不同的可变形模型只促进了其中的一种(通常是交互作用)，而损害了另一种(生物力学现实主义)。在本文中，我们给出了已开发的不同变形模型的分类。我们介绍了每种方法的优点和缺点。最后，我们对可变形模型进行了比较，并对可变形模型的现状和未来进行了评价。(C)2004年，爱思唯尔爱尔兰有限公司出版。
Simulating the behaviour of elastic objects in real time is one of the current objectives of computer graphics. One of its fields of application ties in virtual reality, mainly in surgery simulation systems. In computer graphics, the models used for the construction of objects with deformable behaviour are known as deformable models. These have two conflicting characteristics: interactivity and motion realism. The different deformable models developed to date have promoted only one of these (usually interactivity) to the detriment of the other (biomechanical realism). In this paper, we present a classification of the different deformable models that have been developed. We present the advantages and disadvantages of each one. Finally, we make a comparison of deformable models and perform an evaluation of the state of the art and the future of deformable models. (c) 2004 Published by Elsevier Ireland Ltd.
