对特定的行使用glLineWidth而不影响其他行 [英] Use glLineWidth for a particular line without affecting other lines

问题描述

我是OpenGL的新手.我只是想使用glLineWidth来加粗一行，但这也会影响所有其他行.因此，我尝试了另一种方法，将glLineWidth放在开始和结束之间，然后就没有用了.我的代码如下所示:

I'm new to OpenGL. I simply want to thicken one line using glLineWidth, but that also affects all other lines as well. So I tried the other way by putting glLineWidth inside between begin and end, then it didn't work. My code is shown below:

glBegin(GL_LINES);
glLineWidth(3);
glVertex2f(5, 10);
glVertex2f(30, 35);
glEnd();

glBegin(GL_LINES);
glVertex2f(20, 25);
glVertex2f(50, 55);
glEnd();

那么有什么方法可以使这条线变粗吗?我一直在谷歌搜索，但找不到简单的解决方案:S

So is there any way to make only this line thicken? I've been googling but can't find a simple solution :S

推荐答案

您尝试过这种方法吗?

glLineWidth(3);
glBegin(GL_LINES);
glVertex2f(5, 10);
glVertex2f(30, 35);
glEnd();

glLineWidth(1);
glBegin(GL_LINES);
glVertex2f(20, 25);
glVertex2f(50, 55);
glEnd();
