摘　　要：论文通过参数化数字人体建模得到低分辨率的三维人体网格模型,但网格曲面不够光滑,不能够满足实际应用的要求。为实现数字人体几何模型的光顺效果,论文提出了一种基于Sqrt3细分算法的三维人体模型网格平滑方法。实验证明,该方法对基于参数化建模方法的、多曲率网格人体模型取得了很好的效果,实现简单高效,特征保持效果好。In this paper,a 3D human body meshed model with low resolution is obtained by parametric digital human model. ing,but the meshed surface is not smooth enough to meet the requirements of practical application. To achieve the smoothing effect of the geometric model of digital human body,this paper proposes a mesh-smoothing method of 3D human model based on Sqrt3 subdivision algorithm. Experiment shows that this method applies to the multicurvature mesh body model based on parametric model. ing method and achieves good results. The method is simple,efficient and of well-reserved feature.
