摘　　要：实体建模技术是当今科学和工程计算相关领域的重要研究内容。通过实体建模方法对物体外形进行恰当的描述,从而确定给定的计算区域,是科学与工程数值模拟计算的前提。此外,实体建模技术也是计算机图形学,计算机动画,科学计算可视化等领域相关应用实现的基础。本文系统回顾了当前各类主流实体建模方法,其后重点对隐式几何建模技术相关的理论和方法进行了阐述,分析了实体建模领域现在存在的问题和技术局限性,对未来该领域的发展趋势进行了展望。Solid modeling technology is an important research topic in the field of science and engineering computing. It is the premise of scientific and engineering numerical simulation to describe the shape of the object appropriately by solid modeling method, so as to determine the computational domain. In addition, solid modeling is also the foundation of applications in the fields such as computer graphics, computer animation and visualization in scientific computing. This paper reviews various current mainstream solid modeling methods, and focuses on the theories and approaches of implicit geometric modeling. We also analyze the existing problems and technical limitations of current solid modeling methodologies, and give the research prospect of this field.
