Cartographical Data Treatment Analysis for Real Time Three-Dimensional Terrain Visualization

Flávio MelloLuiz Felipe Ferreira da Silva

The real time three-dimensional terrain visualization is associated to several characteristics, such as the video board exhibition. Moreover, the representation of a virtual scene is carried out through compositions of triangles that together confer a three-dimensional aspect to the scene. The available details in this scene are directly related to the number of triangles amount used in its representation, what may become impeditive to applications like computer visualization. This article presents techniques for cartographic data processing, in order to use them these data in a real time three-dimensional terrain visualization system.
