Hi Luc, 2008/7/10 Frauciel Luc <[EMAIL PROTECTED]>:

Try of quad in a HUD, with screen coordinates extracted from your text, and > something smart with z-buffer parameters to have your text over your quad :) > > Luc > > > Luc FRAUCIEL - BRGM > Unité Calcul, 3D et réalité virtuelle > Service Systèmes et Technologies de l'Information > 3, av C.
