摘要
自由变形(FFD)是计算机人脸动画和表情编辑的常用方法,但对控制点的反求和变形结果的不直观是该方法的不足。提出了基于直接点操作网格的变形方法,通过鼠标的交互编辑,可以直接得到可控制的变形结果。试验结果表明该方法简单有效。
FFD （Free Form Deformation） is general approach for computer facial animation and express editing while troublesomely solving control point and unconspicuous deformation result.A new approach is presented as point-based operation for mesh deformation,from which deformation result can be directly obtained by interactive mouse operation.Experiments also show the method is simple and effective.
