Porbleme avec les textures.

Bonsoir tout le monde.
j'ai un petit probleme avec les textures.
Je suis entrain de modeliser un chateau.si j'active la texture sur un cube bien precis tout le chateau prend cette texture.

voila un bout du code:

Code:

---

1 2 3 4 5 6 7

Cube mur1(Vector(0,0,0),Vector(5,290,130),"brique.bmp"); Cube mur2(Vector(0,0,0),Vector(-390,5,130),"terre.bmp"); Cube mur3(Vector(0,0,0),Vector(5,290,130),""); mur1.Render(camera); mur2.Render(camera); mur3.Render(camera);

---

tout les murs prennent la texture "terre" alors que normalement je devrais avoir trois mur differents.
dans le rander de Cube je fais un glBindTexture et un glDisable;

Merci de votre aide

Le code que tu nous as mis ne sert pas grand chose...

Pourrais tu mettre le de ta méthode Render() ?

Normallement, glBindTexture doit être appelé entre chaque rendu de géometrie

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

// cube 1 glBindTexture(); glBegin( ... ); ... glEnd()   // cube 2 glBindTexture(); glBegin( ... ); ... glEnd()   // cube 3 glBindTexture(); glBegin( ... ); ... glEnd()

---

voila la fonction render

Code:

glBindTexture(GL_TEXTURE_2D,tex_Mur[0]);

Tu ne prendrais pas toujours la même texture ?? vu que l'index de ton tableau est toujours 0 ??

Mais si je fait
Cube mur1(Vector(0,0,0),Vector(5,290,130),"brique.bmp");
Cube mur2(Vector(0,0,0),Vector(-390,5,130),"terre.bmp");

normalement je devrais avoir 2 structure differentes
mais c'est pas le cas

Tout dépend de ce qu'est ton tableau "tex_Mur" ..

Peux tu mettre le code complet de ta classe cube (.h et .cpp )?

ET juste un petit truc comme ca .. il faut définir tes coordonnées de texture pour chaque vertex ... avant glVertex()

Code:

---

1 2 3 4

glNormal(); glTexCoord(); glVertex();

---

voila le .cpp

Code:

voila le .h

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12

class Cube : public Shape { protected : Vector a,b; //!< Extremites du cube public : Cube(); Cube(const Vector&,const Vector&,char *); ~Cube(); void Render(const Camera&); };

---

Donc voilà ton problème, c'est un problème C++ ;) indépendant d'openGL

tex_Mur est défini comme une variable globale à TOUT ton programme.

Donc a chaque création d'un cube, ta valeur est écrasé par une nouvelle valeur.

Pour avoir cette notion de tex_Mur par Cube, tu dois définir ton tableau comme attribut :

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12

class Cube : public Shape { protected : Vector a,b; //!< Extremites du cube GLuint tex_Mur[1]; public : Cube(); Cube(const Vector&,const Vector&,char *); ~Cube(); void Render(const Camera&); };

---

Ainsi, tu aura un tex_Mur par instance de ta classe Cube.

Bon courage

merci beaucoup raptor70 pour ton aide ça marche nickel.
