Re: Any tips for using GLUT

["Blake L. Carlson" <blake-carlson uiowa edu>]

Michael -

I've tracked down the bug to this GLUT init command:

      glutInitDisplayMode( GLUT_INDEX | GLUT_DOUBLE );

It seems that indexed mode is not working on my system. I know that this
initialization command does work:

      glutInitDisplayMode( GLUT_RGB | GLUT_DOUBLE );

(See /usr/lib/Mesa-3.0/demos/drawpix.c if you have the Mesa demos
installed)

We really need the GLUT_INDEX mode, otherwise I'm going to have to do a
major overhaul in some of our SGI libraries to port to alpha.  

Does this stir up any memories???
