<p>How do you render primitives as wireframes in OpenGL?</p>

From
http://cone3d.gamedev.net/cgi-bin/index.pl?page=tutorials/ogladv/tut5
```
```
// Turn on wireframe mode
glPolygonMode(GL_FRONT, GL_LINE);
glPolygonMode(GL_BACK, GL_LINE);

// Draw the box
DrawBox();

// Turn off wireframe mode
glPolygonMode(GL_FRONT, GL_FILL);
glPolygonMode(GL_BACK, GL_FILL);
```
```
