摘要
为实现仿真手在运动过程中符合人手的生理特性及运动特点,文中通过分析手的解剖结构,总结控制手部运动和形状的约束参数,采用层次建模方法,先建立用线段表示的含有约束参数的手部骨骼模型,然后在此基础上根据手部的特征横截面确定特征多边形,采用NURBS面片拟合的方法建立依附于骨骼之上的肌肉模型。此方法建立的手部模型在运动仿真过程中,手部肌肉以对应的骨骼为轴线并随着骨骼各个参数的变化而发生相应的变化,最终取得良好的仿真效果。
In order to carry out an emulational hand that moves according to human hand's anatomy and movement characteristic,in this article,by analyzing the anatomy structure of human hand,summarize the constraints of controlling hand motion and shape,adopts a modeling method with a hierarchical structure.Fistly,establish hand skeleton model which contains constraints and expresses as lines, then basing on the former adopt NURBS patches to synthesize according to characteristic polygons that are obtained by characteristic cross sections, and establish muscle model that adheres to skeleton .During the emulation of this hand model, hand muscle changes as the change of each constraint of hand skeleton circling the skeleton.Finally,good emulation effect is gained.
