- W2387664523 abstract "This paper presents a dynamic construction algorithm for the multi-resolution terrain model based on the large scale GRID data or discrete elevation data. We calculate the field of vision following the theory of three dimensional perspective projections. In the field of vision, the hierarchical triangulated irregular network (HTIN) is constructed through hexa-splitting of triangle, which is determined with three criterion: the complexity of terrain, the position of view point and the orientation relation between terrain tile and the line of sight. The HTIN is organized by quad-tree which includes trinary tree node. This algorithm optimizes the shape of HTIN and improves the efficiency of constructing. The experiment results show that this algorithm can achieve good performance both on the quality of landscape and on the speed of the rendering." @default.
