## 一、项目说明
|
||
|
||
1. 此项目为我在学习过程中的一些分享和实现，因此项目名字以 **`Demo`** 为后缀。
|
||
2. 项目重点在于 **「渔」**，不在于 **「鱼」** 。
|
||
3. 如果你有意将此Demo中的效果加入到你的项目中，**请认真评估是否适合你的项目使用！**
|
||
4. 本项目支持 Cocos Creator `v2.2.1` 、 `v2.2.2`
|
||
1. 项目当前正在使用 v2.2.2 开发
|
||
2. 如果采用 Cocos Creator v2.2.1打开，在打开的时候，Cocos Creator 会提示有降级打开项目的提醒，忽略直接打开即可
|
||

那么现在，我们先来轻松地看下有哪些特效效果吧~
|
||
|
||
## 三、特效预览
|
||
|
||
|
||
|
||
### 内发光（[实现原理](https://www.jianshu.com/p/326b73f86ecc)）
|
||
|
||
|
||
|
||
### 马赛克/像素化（[实现原理](https://www.jianshu.com/p/40e72ab76afd)）
|
||
|
||
|
||
|
||
### 老照片（[实现原理](https://www.jianshu.com/p/711a54ff2fa0)）
|
||
|
||
|
||
|
||
### 灰度渐变（实现原理同老照片一样，可参考[老照片实现原理文章](https://www.jianshu.com/p/711a54ff2fa0)）
|
||
|
||
|
||
|
||
### 点光（[实现原理](https://www.jianshu.com/p/8ff03b34b0bd)）(2020.01.12更新）
|
||
|
||
|
||
|
||
### 扫光（实现原理同点光一样，可参考[点光实现原理文章](https://www.jianshu.com/p/711a54ff2fa0)）(2020.01.13更新）
|
||
|
||
|
||
|
||
### 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)
|
||
|
||
**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
|
||
|
||
|
||
|
||
### 圆角裁剪-v2（2020.01.17更新）
|
||
|
||
在 **圆角裁剪-v1** 的原理基础上，新增支持任意宽高纹理的圆角裁剪
|
||
|
||
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
|
||
|
||
|
||
|
||
### 高斯模糊-V1（[实现原理](https://www.jianshu.com/p/9e42cbb1d4a8)）2020.02.07更新）
|
||
|
||
|
||
|
||
### 外发光（完善中...）

||
### 外描边（完善中...）
