一个计算机动画转头模型

本文提出一个用于计算机动画的转头模型。它利用头部的正面和侧面形象来构造出头的三维结构形象，然后按指定的旋转轴旋转该结构，经过边缘轮廓提取及隐线消除，最终得到正确的转头过程序列画面。

A HEAD TURNING MODEL FOR COMPUTER-AIDED CHARACTER ANIMATION

A head turning model for computer-aided character animation is presented in this paper. Assume two extreme key frames are adopted,one is front head image, the other is profile head image. After a head skeleton is constructed,cut planes are utilized to cut this skeleton to get control points. Those points are interpolated to get cut selection of the head which are piled up to construct a three dimensional head image.By specifying the rotation axis, edge detection and hidden line removal, the model can generate correct head turning inbetweens.
