METHOD FOR DRAWING STEREOSCOPIC MAP, AND NAVIGATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a drawing method giving almost an actual impression by preventing a structure from being discontinuously drawn due to mesh boundaries at the time of reading map information on roads, buildings, etc., divided by mesh boundaries from a map database, and displaying a stereoscopic spectacle viewed from a prescribed view point position. SOLUTION: This device recognizes (step 602) whether a structure data read from a map database is a non-divided structure or a divided structure, and in the case of a divided structure; stores a starting position and an end position of a texture to be mapped or stuck on the reconstructed structure after having changed the drawing attribute of the mesh boundaries (step 607) and reconstructed the divided structure into a single structure before division; sequentially performs mapping on the side of the divided structure; and thus sticks textures of the windows to the side of the structure (step 609).
