Abstract: This paper discusses the algorithm of texture mapping based-on topographic map to produce the 3D images. The main procedure includes: obtaining the topographic data; determinning the translation relation among the scene space, the texture space and the screen space; antialiasing methods; the light model etc.At last, the test results by using the topographic data and the summary are showed
