| 摘 要： | 3维地质体的重构是3DGIS的一个重要研究方向,在地质与矿山等领域十分重要,但这一方面尚需大量细致深入的研究工作。在总结已有工作的基础上指出四面体格网是目前表达和重构地质体的最佳结构,同时提出了以简化的面约束条件重构各类复杂地质体的方法及表达具有属性渐变和属性突变特性的地质体的方法。

| Abstract: | Research on reconstructions of 3 dimensional (3D) geological bodies is very important in the fields such as geologic and mining, but detailed and advanced works are in great needs. In this paper, we point out that tetrahedron mesh is the best structure for the representation and reconstruction of geological bodies on the base of a summary of present works, and we also put forward a method to reconstruct complex geological bodies on the base of simplified face constraint conditions, and a method to represent geological bodies that have gradually changed attributes and sharply changed attributes. |
