une face de mon cube ne se dessine pas

**jeandormesson** · 04/10/2006, 14h49

Hola flasheurs.

voila, j'ai un pavé dessiné en 3D par du code. je voudrais l'avoir dans une position particulière. pour cela je lui applique une série de rotations définies aussi dans mon code. Quand j'applique les rotations, il me redessine mon pavé, mais il oublie une face!!!! si ensuite je clique sur un bouton créé pour faire une rotation pas à pas, la face se dessine. Mais au final, je ne veux pas de ce bouton. Je veux que à la compilation de ma séquence la face soit déssinée.
D'ou vient le problème?

Je vous joins 2 sources: la première c'est mon pavé qui marche pas, et la deuxième c'est le même code, excepté que le pavé tourne en fonction de la souris (pour que vous voyez que la face se dessine normalement

!!)

merci de votre réponse

salut
je comprends pas trop le prob

j'ai changé 2 ou 3 trucs et la forme 3D se dessine dans l'angle que j'ai choisi (j'ai rajouté un argument dans la function refresh).
voici le code modifié

Code :

Regarde bien le code que tu m'as donné ou le mien. Quand tu le compile, tu vois le pavé dessiné, mais la face carrée au premier plan n'est pas déssinée (elle devrait etre pleine comme sur l'autre source que j'ai donnée et donc on ne devrait pas voir les traits des faces du dessous et du coté). La face qui ne se dessine pas s'appelle face1.

une face de mon cube ne se dessine pas
