### 圆角裁剪-v1（2020.01.17更新）
> * 声明：此特效为搬运过来的特效，非原创。
> * 修改的地方：搬运后，在原来的主要代码上加入了自己的理解注释
> * 实现原理：参考文章 [《圆角计算 Shader》](https://www.cnblogs.com/jqm304775992/p/4987793.html)
> * 参考代码：Cocos 论坛帖子[《分享更高效的 creator 裁圆角头像 shader》](https://forum.cocos.org/t/creator-shader-2019-10-22-2-2-0/82548) 和对应的 [实现代码](https://github.com/yanjifa/shaderDemo/blob/master/assets/Effect/CircleAvatar.effect)
![](static/effects/2d-sprite-round-corner-crop.gif)
**此版本存在局限性：只有在正方形纹理上，才能裁剪出圆角，在非正方形上，无法裁剪出圆角，具体变现为有拉伸效果**
如：下面GIF中第3到5秒演示所示，黄色和红色的非正方形纹理的圆角明显被拉伸
![](static/effects/2d-sprite-round-corner-crop-v1.gif)
### 圆角裁剪-v2（2020.01.17更新）
在 **圆角裁剪-v1** 的原理基础上，新增支持任意纹理的圆角裁剪
如：下面Gif中第3到5秒演示所示，黄色和红色的非正方形纹理也能裁剪出圆角效果
