人舌及嘴部的3D肌肉控制模型

3D muscle-controlled tongue and mouth model

提出了一种人舌及嘴部三维肌肉控制模型.该模型根据解剖学结构及舌部运动特征,由内部舌体和外部嘴部组成.舌体运动由3类共6条肌肉控制,嘴部运动由3类共9条肌肉控制.模型建模及驱动比较方便,并已在PC机上进行了模拟,结果表明,舌体运动较逼真,可较好地模拟人舌及嘴部运动及部分表情.

A 3D muscle control tongue and mouth （3D-MCTM） model are presented in this paper. Based on anatomy and tongue＇s moving characteristic, the model consists of two parts the inner model and the outer model. Outer mouth is controlled by nine pieces of muscle which respectively belong to three different kinds, while the tongue is controlled by six pieces of new muscle. The modeling and animation is convenient. The experiments on PC show that the tongue model is realistic, and can simulate mouth movement vividly.
