| Abstract: | The real displaying technology of 3D topography is a key technology for Virtual Reality (VR), but also is a important element of Geography Information System. In this paper, we discussed the mechanism and procedure of real displaying of 3D topography. Moreover, we also discussed the main two methods of drawing and displaying of it. At the same time, a specific example of drawing the 3D topography using the previously method is given. |
