摘　　要：目前3D模型动画在影视、游戏等领域得到了广泛的应用,其基本原理是模型中各顶点的位置随着时间的变化而改变,主要分为Morph动画,关节动画和骨骼蒙皮动画(Skinned Mesh)。骨骼蒙皮动画很好地解决了接缝问题,并因其逼真、灵活的交互效果而广受欢迎。本文以智慧城市建设中三维网络教学平台为应用背景,对3D动画中的骨骼蒙皮动画技术原理进行了详细的阐述和分析。并对几种关键帧插值算法进行了比较,期望能更好的改善画面质量,同时提高骨骼蒙皮动画的运行速度,从而优化网络教学平台的视觉效果。Currently 3D model animation has been widely used in film, television, games and other fields. The basic principle o 3D model animation is that the position of each vertex of the model will change in different time. It can be divided into Morph animation, Skeleton animation and Skinned Mesh animation. Skinned Mesh animation solves the problem of seams. And it is popular because of its realistic, flexible interaction effects. In the application background of three-dimensional e-learning platform, this article describes the principle of skinned mesh animation technology, and compares three kinds of key frame interpolation methods. We hope to improve the picture quality while increasing the run speed of Skinned Mesh animation. Meanwhile, the visual effects of the network teaching platform can be optimized.
