Embodiment Construction
[0027] The method for automatically generating the three-dimensional terrain in the Torque engine of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0028] The embodiment of the invention is divided into two parts:
[0029] The first step is to automatically generate a height map based on topographic map data
[0030] 1. If figure 1 As shown, according to the terrain range to be created, determine the topographic map frame where it is located, and then extract information such as elevation point 1-1, contour line 1-2, etc. according to the geographic element layer where the elevation information is located;
[0031] 2. Use a point-by-point insertion algorithm for all discrete points to construct a Deluanay (Diloni, Russian mathematician) triangulation, and then insert each contour line into the triangulation as a constraint edge to generate a constrained Delaunay triangulation 1-3;
[0032] 3. According t...
