2013年3月19日 · ten模型主要有四个基元构成：四面体、三角形 、边和节点 。 一个空间实体由四面体组成，面由三角形组成，线由小三角形的边组成，点由节点组成。 总之，在TEN模型当中，每个节点必须属于某一条边，每条边属于某一三角形，每个三角形属于某一个四面体。

Triangular irregular networks (TIN) have been used by the GIS community for many years and are a digital means to represent surface morphology. TINs are a form of vector-based digital geographic data and are constructed by triangulating a set of vertices (points).

The Tetrahedral Network (TEN) is a powerful 3-D vector structure in GIS, which has a lot of advantages such as simple structure, fast topological relation processing and rapid visualization. The difficulty of TEN application is automatic creating data structure.

As illustrated in figure 3, the basic elements (the simplexes) of the TEN model (Pilouk, 1996) include node, arc, triangle and tetrahedron. A feature (a complex) in a GIS can be composed of a...

2013年3月19日 · 在三维空间建模方法中，TEN模型的生成算法应用非常广泛，主要有基于三维栅格的TEN模型生成算法和基于矢量的TEN模型生成算法。 什么是TEN模型？ TEN模型主要有四个基元构成：四面体、三角形 ... 概念: TEN模型主要有四个基元构成：四面体、三角形 、边和节点 。 一个空间实体由四面体组成，面由三角形组成，线由小三角形的边组成，点由节点组成。 总之，在TEN模型当中，每个节点必须属于某一...
