Abstract: A parametric method for 3D human modeling is proposed in this paper. A set of feature
parameters are defined to control the topological structure of human body comprising ten parts.
Zhang spline is then used to construct the human surface of each part. Real-time garment dressing
simulation is implemented based on the integrated human model. As an improvement of traditional
mass-spring method, large-span bend spring is proposed for the purpose of wrinkle simulation.
Furthermore, proper setting of parameters along with multistep correction strategy enables simulation
of different fabric materials, namely cotton, silk and elasticity. The experimental results show that our
system can construct relatively realistic human model as well as realize complete and flexible
garment dressing simulation in real time.
