【摘要】 计算机曲面描述通常采用两种方法:用数学函数曲面表示方法(即连续曲面)和用离散的数据点与相应点间的拓扑关系表示曲面(即网格曲面)。高光线模型是一种可视化的曲面品质分析模型。这里将连续曲面的高光线模型拓展应用到三角网格曲面中,提出了三角网格曲面高光线模型的定义并对三角网格曲面高光线的相关性质及其追踪方法进行了探讨。更多还原

【Abstract】 There are two ways to present a surface for the purpose of visualization and co mputation. One is to use analytical surface patches via functions(i.e. contin uous surface). Another is to use discrete data structures (i.e. triangular me sh surface). The highlight-line model is a visual tool in assessing the qualit y of a surface. The definition of highlight-line model for triangular mesh surf ace is put forward. It’s properties and tracing method are discussed.更多还原
