Unity shader bloom效果

Bloom的实现原理，1：首先根据一个阈值提取出图像中较亮的区域，2：再利用高斯模糊对这张亮度数值进行模糊处理，3：模拟光线扩散的效果，最后再将其和原图像进行混合，得到最终的效果。代码如下：Shader "Unlit/TestBloom"{Properties{_MainTex("Main Texture...

shader 高斯模糊

高斯模糊主要用到了正态分布曲线。我们用到了正态分布矩阵：static const half4 GaussWeight[7] ={half4(0.0205,0.0205,0.0205,0),half4(0.0855,0.0855,0.0855,0),half4(0.232,0.232,0.232,0),half4(0.324,0.324,0.324,1),half4(0.232,0.232,0.23...

三角形重叠算法

判断两个三角形是否有重合部分：1：判断两个三角形是否相交a：判断两个三小型的所有边是否存在相交2：判断两个三角形是否包含关系a：判断一个三角形的顶点和另一个三角形所有顶点连线 与 该顶点对应的边是否相交。C#代码如下：using System.Collections;using...
