摘　　要：构建真三维模型是地质学、三维GIS、科学可视化及工程应用领域共同关心的课题。笔者提出了基于TEN的三维离散数据的构模,详细说明了从离散的三维初始数据点建Delaunay四面体网格的算法和步骤。算例表明,该算法能够较好地生成任意形状三维地质体。The true three-dimensional modeling is a common subject in such fields as geology, three-dimensional GIS, scientific visualization and engineering application. This paper has presented a new three-dimensional data model based on TEN, and introduced TEN generation algorithm and steps. Practical examples indicate that this algorithm can satisfactorily produce the tetrahedral unit grid of the arbitrary shape three-dimensional geological body.
