| Abstract: | The purpose of this research is to find out new method for gathering 3D information from traditional maps and displaying such information with 3D graphics.This research involves Vector Geometry and MS Direct3D technology.This article mainly describes the technology of gathering information from maps and the generation of 3D terrain based on such information by using Direct3D and vector geometry,and then describes the realization of walking simulation on such terrain,and how to optimize the whole procedure.The research is a success,and the software with described functionality was created.This technology can reduce geography research expense because the information source is existed map and it uses cheap hardware(scanner)and popular software(Direct3D)technologies. |
