物体沿一条曲线变形是动画中的常见问题,本文提出了一个沿Bezier曲线的物体变形模型。该模型首先根据曲线的形状,构造一个把物体空间映射到曲线局部空间的三次Bezier体,然后由Bezier体的参数表达式实现物体沿曲线变形。该方法简单且易控制,在动画制作中具有应用价值。 Object deformation along a curve is a common problem in animation, this article presents a Bezier curve of the object deformation model. Firstly, according to the shape of the curve, the model constructs a cubic Bezier body that maps the object space to the local space of the curve, then the deformation of the object along the curve is realized by the parametric expression of the Bezier body. The method is simple and easy to control and has application value in animation.
