Abstract: In this paper, a kind of Unique Face Model technology is set up according to different object models and Independent Mesh Model object in order to achieve the target optimization and solve the problems in vast digital model structures. This method provides solution to the establishment of large capacity model with low-level software and hardware, and working efficiency is greatly improved. The virtual objects and real images are seamlessly integrated.

Key words: 3DSMAX, CAD, 3D digital modeling, digital city, unique face model
