Texture avec Cube mapping

Bonjour à tous,
Je suis entrain d'apprendre l'OpenGL et on me demande de faire du cube mapping. J'ai compris le principe de cette technique mais comme je ne connais pas grand chose à ça je ne vois pas du tout ou est le problème dans ce petit programme que j'ai fais.
En effet, ce programme devrait m'afficher un cube avec sur fond noir avec l'effet cube mapping dessus. Le cube apparait bien mais tout blanc. Pourriez-vous m'aider s'il vous plait car mon boss commence à s'impatienter :lol:

Voici le code :

Je vous remercie d'avance pour votre temps que vous consacrer à mon petit soucis.

Les glTexCoord2f, ça ne devrait pas plutôt être des glTexCoord3f ?

bin je veux bien mais qu'est-ce que je met en parametre x,y et z ? la je comprend pour glTexCoord2f(x, y) mais apres pour glTexCoord3f(x, y, z) que veut dire le z ?

Bah par exemple pour la face des x negatifs:

Code:

glBegin(GL_QUADS); glTexCoord3f(-1.f, -1.f, -1.f); glVertex3f(-1.f, -1.f, -1.f); glTexCoord3f(-1.f, 1.f, -1.f); glVertex3f(-1.f, 1.f, -1.f); glTexCoord3f(-1.f, 1.f, 1.f); glVertex3f(-1.f, 1.f, 1.f); glTexCoord3f(-1.f, -1.f, 1.f); glVertex3f(-1.f, -1.f, 1.f); glEnd();

Pour faire du Cube mapping il te faut créer une texture cubemap comme une texture 2D dans ton initialisation.

Tu peut aussi passer par un shader, c'est encore plus simple :mrgreen: !

Super ca marche niquel, le soucis venait déjà que j'avais mis en commentaire glEnable(GL_TEXTURE_CUBE_MAP) puis quelque probleme dans le parametrage de mes textures.

Merci beaucoup vous etes des chef ;)
