Unity 3d animation data compression method and system

The invention provides an animation compression method and system based on Unity3d (Unity 3d). According to the method, corresponding compression parameter thresholds are set for different skeleton nodes of animation data key frames, and key data frames of all skeleton nodes in animation data are removed in sequence to achieve simplification of the animation data; and the simplified animation data is processed by adopting a smooth curve so as to improve the problem of deformation of the compressed animation. Through the technical scheme provided by the invention, the size of the animation data can be greatly reduced under the condition that the animation data is almost not deformed. 本发明提供一种基于Unity3d的动画压缩方法及系统。该方法根据为动画数据关键帧的不同骨骼节点设置相应的压缩参数阈值，依次对动画数据中各骨骼节点的关键数据帧进行剔除处理实现对动画数据的精简；并对精简后动画数据采用平滑曲线进行处理以改善压缩动画走样的问题。通过本发明提供的技术方案可以在动画数据在几乎不走样的情况下，大幅减少动画数据的大小。
