Three-dimensional map drawing method and navigation apparatus |
摘要 |
<p>Whether the structure data read from the map data correspond to a non-decomposition structure or a decomposition structure, the drawing attribute of the mesh boundary is modified for the decomposition structure, and textures such as windows are mapped on the side wall of the structure by mapping the texture on the side wall of the structure reconstructed after reconstructing the single-bodied structure before decomposition, or mapping the texture progressively on the side wall of the decomposition structure with the stored start point and end point of the texture to be mapped. <IMAGE></p> |
