Re: [Haskell-cafe] HopenGL

Hi, Thanks for the reply. The Lines.hs example program seems to work just right. Unfortunately I still can't get colored lines to work in my 3d program. Maybe it has something to do with the fact my one is 3d and the example program is in 2d. Any other ideas? I would post some source code but there's quite a lot of code.

If anyone knows how to get HOpenGL to draw coloured lines, I'd like...

See http://cvs.haskell.org/cgi-bin/cvsweb.cgi/~checkout~/fptools/ libraries/GLUT/examples/RedBook/Lines.hs

Note the color line which in this example uses white.

For debugging purposes play with clearColor because you can use that to test whether you're rendering the infamous black-on-black image or simply rendering nothing :-)

(Disclaimer: For some reason, today I can't test any of the redbook examples because Graphics.UI.GLUT is missing from my current installation. I'm guessing that if you have a non-broken installation they will mostly work fine. I certainly had no problem rendering lines based on these examples when I last had a non-broken installation.) -- Dan
