| Abstract: | With the development of Virtual reality technology and the popularization of smart devices,the development and application of virtual geography teaching systems have received more and more attention. Software Unity3d has won the favor of developers due to its excellent performance in virtual reality development. This paper analyzes in detail the functional requirements of 3D virtual geography teaching system and the realization characteristics of different technology platforms. Taking the advantage of the rendering capabilities provided by Unity’s own powerful engine,the tile map pyramid model is built successfully,which provides a solution for geographic video texturing. Hence,the applicability of Unity3D for virtual geographic system development is verified. |
