今天工作中需要做一个事情: 在shader内部做一些空间距离上的计算,而且需要对所有的点进行计算,符合条件的显示,不符合条件的点不显示. 思路很简单,在vertex shader内知道顶点坐标,进行计算,算好以后判断是否需要显示,例如设置alpha值,那么再将alpha值传给fragment shader,在里面设置alpha的值就好了. 基本代码如下 // vertex shader #version 300 es in vec4 vPosition; in vec2 vTexCoord; o
之前GGJ实现了一个,但是实现方式上有很多冗余.今天正好在做一个类似的东西,重新做了一个版本 还是当时美术画的素材: 由于里表世界是不同的内容,是两张材质.所以拆分成不同Layer之后,里世界单独渲染一次 最后用Graphics做一下混合的屏幕处理即可. 脚本: using System.Collections; using System.Collections.Generic; using UnityEngine; public class CustomRender : MonoBehavio
