%X MIP Mapping technique is very efficient for anti-aliasing in texture mapping, But as a conventional method, MIP Mapping selects the appropriate resolution texture according to the rendered sizes only, so at the initiation all levels of textures are loaded on the memory, which can reduce the efficiency of computer. When displaying large 3D urban maps, sometimes the lowest resolution texture is enough. To solve this problem, a view-based method of controlling texture on 3D maps was proposed. The appropriate texture level was decided mainly according to two criteria, One was rendered sizes with viewpoint, The other was the importance of the texture on view. The test results show that the developed method can improve computing efficiency.
