建议早点放上 performance benchmark,个人关注:文件尺寸、播放时的 CPU&内存 占用

Lottie 性能很差,VAP 思路非常好,火钳刘明

Lottie是矢量动画,vap实质是视频动画,原理不相同,很难进行性能对比。

比如一个简单的矩形位移动画,矢量动画明显具有极大优势。但在复杂动画方面vap(视频方案)优势非常明显,因为无论画面内容是简单还是复杂,其消耗(GPU与CPU消耗)并不会有太大差别。

而Lottie为代表的矢量动画无法实现复杂特效,比如3D效果,粒子特效等。正因为这些区别很难用一套统一标准素材来进行性能测试对比。比如介绍里也放出了一个性能对比表格,我们测试用的素材,用lottie就无法导出。
