R&D of a Parameterized Method for 3D Virtual Human Body Based on Anthropometry

The traditional individual 3D virtual humand modeling method has drawbacks of mass data and complex post-processing. It doesn’t suit the Web application. The research presented in this paper is to propose a novel real-time approach of 3D human parameterized modeling based on anthropometry. According to the principle in Anthropometry and Anatomy, the model surface is divided into several parts. The human crosssection of torso and limbs are simulated by surper-ellipse curvers. Some feature points are selected from supre-ellipse curvers to generate the Nurbs surfaces of torso and limbs. A hiberarchy parameterization driven mechanism based on Anthropometry data is used to calculate parameter values during the humand model generating. The experiment result indicates that the method is flexible, little data quantity, easy-control, realistic and exact, and fit for many Web applications such as virtual image-building, virtual human motion and virtual try-on.
