View Full Version : Drawing lines on top
02-20-2001, 07:48 AM
I'm working on an app that draws many polys and lines. I want certain lines to draw on top of everything else. How do I do this? Right now I have
glVertex3d(v1x, v1y, v1z);
glVertex3d(v2x, v2y, v2z);
glVertex3d(v3x, v3y, v3z);
glVertex3d(v4x, v4y, v4z);
It's drawing the line underneath everything.
Thanks for your help.

If you disable depth testing (glDisable(GL_DEPTH_TEST)), any new line will be drawn over the old ones. That however disables the z-test, so also object that you would like not to see might be drawn then.

I think you might find glPolygonOffset to be of use.

Yeah, DFrey, you're always falling in my back with your idiotic answers. Geez. http://www.opengl.org/discussion_boards/ubb/smile.gif Well, just cleaned my room (or how'd you say?). Gives a great flair and feeling. You should clean your room as well! http://www.opengl.org/discussion_boards/ubb/smile.gif Well, I'm a bit unclean in the other time...

Oh, say, Stephanie, what's your age? http://www.opengl.org/discussion_boards/ubb/smile.gif

Thanks to everyone for all the help. I think I have it.
Just out of curiosity, why is my age relevant?

Well, your name appeared to be feminine...
