Problème de rendu entre model 3D et un string 2D (Slick-util + LWJGL)

**isador34** · 31/01/2015, 12h19

Bonjour a tous, je viens vous demander votre aide pour un petit soucie dans mon code.
je vous montre un petit screen:

comme vous pouvez le voir le string fait n'importe quoi, il est en l'envers (miroir) et ne devrai pas se trouver a cet endroit, il devrai être constamment au position x=10 et y=10 de la fenêtre, la j'ai l'impression qu'il est considéré comme une partie du model.

mes codes:
