This article presents an alternative solution for the triangulation problem of altimetric data of cartographic features. This triangulation corresponds to one of the phases of the methodology to be presented. The proposed mechanism helps to enhance the performance of the graphic hardware by reducing the number of primitives to be processed during the exploration of the environment. The main goal of this method is
to allow data management obtain real time three-dimensional (3D) terrain visualization from 2D topographic charts. This application is supposed to be executed on low performance computers embedded on military tanks and vehicles. Thus, the methodology is constrained by this obsolete hardware. |
