空间变形方法是一系列建模和动画技术，用于通过扭曲周围空间来间接重塑对象，其结果类似于塑造高度可塑性的物质。它们的优点是在计算上是有效的(因此是交互的)，并且适用于各种对象表示。在这篇文章中，我们综述了空间变形的最新进展。由于直接操纵环境空间是不可行的，变形由不同维度的工具控制-点、曲线、曲面和体积-正是在此基础上，我们对它们进行分类。与以前专注于提供单一基础数学形式主义的调查不同，我们使用以用户为中心的多功能性、易用性、效率和正确性标准来比较技术。
The spatial deformation methods are a family of modeling and animation techniques for indirectly reshaping an object by warping the surrounding space, with results that are similar to molding a highly malleable substance. They have the virtue of being computationally efficient (and hence interactive) and applicable to a variety of object representations. In this article we survey the state of the art in spatial deformation. Since manipulating ambient space directly is infeasible, deformations are controlled by tools of varying dimension—points, curves, surfaces and volumes—and it is on this basis that we classify them. Unlike previous surveys that concentrate on providing a single underlying mathematical formalism, we use the user-centered criteria of versatility, ease of use, efficiency and correctness to compare techniques.
