摘要
提出参数化的人体建模方法。将人体分为10个部分,并且定义了一系列特征参数用来控制人体的拓扑结构。文献[1]中提出的Zhang样条曲线被用于构造每个部分的人体表面。在完整人体模型的基础上,实现实时的着装模拟。在传统弹簧质点模型的基础上提出大弯曲弹簧以实现褶皱效果。另外,通过合理的参数设置以及多重校正机制实现不同材质的效果,包括丝质、棉质和弹性布料。实验结果证明该系统可以建立较为真实的人体模型,并且能实时地进行较为复杂的试穿仿真。
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.
