标题: 求闪电图像算法
网上找又找不到好的资料，自己做又只能做出这种半调子的畸形出来…



我倒是很想说这哪里看起来像闪电了

关键源码如下：

GLfloat random[50];

for (int i=0;i<51;i++)
{
        random=rand()%200/200.0f;
}
glBegin(GL_QUADS);       
        for (i=0;i<50;i++)
        {
                glColor3f(1.0f,1.0f,1.0f);glVertex3f(i*0.24f-6.0f,random/2.0f,0.0f);
                glColor3f(1.0f,1.0f,1.0f);glVertex3f((i+1)*0.24f-6.0f,random[i+1]/2.0f,0.0f);
                glColor3f(1.0f,1.0f,1.0f);glVertex3f((i+1)*0.24f-6.0f,random[i+1]/2.0f-0.2f,0.0f);
                glColor3f(1.0f,1.0f,1.0f);glVertex3f(i*0.24f-6.0f,random/2.0f-0.2f,0.0f);
        }
glEnd();

已经不错了，你试试看把RAND加大一倍。。。

少年们，我们继续绑着VBO玩SHADER吧
