Abstract: In this paper, an efficient method for customizing individual 3D virtual human body is introduced. Based on the idea of model reuse, the method edits the standard body model according to the values of 21 anthropometric parameters, and generates the body model with the corresponding shape in real time. The proposal possesses a number of merits. Firstly, the method employs 21 anthropometric parameters, to describe the shape of human body perfectly, and satisfies the requirement of individual body model. Secondly, the new model can be driven directly in a virtual environment, and thirdly, the method is capable of generating a new model in real time.
