In this paper, we propose a personalized human body surface modeling method, which is based on a tree structure. Firstly, initial standard models of 3DS format are introduced, which includes the 17 parts of the body. The size of human body model is adjusted according to the body of the external geometry parameters, including the length and girth parameters. Finally the human body model is rebuilt by NURBS surface generator remodeling of the surface. Experiments show that this method can realize the human body surface model reconstruction.
