摘要本文提出了一种动态自适应网格库，该库能保持时变曲面的一致性三角剖分。用户提供初始网格、表面采样程序和一组适应标准。网格会自动修改，以符合用户定义的特征，而表面会随着时间而变化。网格表示基于半边数据结构，没有任何额外的存储需求。网格具有潜在的半规则多分辨率结构。此外，期望网格特征的规范可以基于非常通用的自适应规则。该方案促进了处理三角曲面的图形应用程序的开发。该库源代码可在线获得。
Abstract In this paper, we present a dynamic adaptive mesh library which maintains a conforming triangulation of time-varying surfaces. The user supplies an initial mesh, a surface sampling procedure, and a set of adaptation criteria. The mesh is automatically modified in order to conform to user-defined characteristics, while the surface changes over time. The mesh representation is based on a half-edge data structure without any extra storage requirements. The mesh has an underlying semiregular multiresolution structure. Furthermore, the specification of desired mesh characteristics can be based on very general adaptation rules. This scheme facilitates the development of graphics applications that manipulate triangulated surfaces. The library source code is available online.
