3D et plusieurs textures

Nouveau Nombre de messages : 1 Date d'inscription : 13/03/2006

Salut à tous.

Alors voilà, j'ai un probleme dont je ne trouve pas la solution:
j'ai 2 objets dans ma scene avec chacun leur texture (pcx), mais seule la 1ere texture chargée semble s'afficher (objet blanc)

Voici le code que j'utilise:

Code:: int texture[2];       // Storage For 2 Textures

//initialise la 3D
void Init3D()
{
static bool m_bFirstLaunch = true;
////if (m_bFirstLaunch)
powerON(POWER_ALL);

// Setup the Main screen for 3D
videoSetMode(MODE_0_3D);
vramSetBankA(VRAM_A_TEXTURE);

// IRQ basic setup
irqInit();
irqSet(IRQ_VBLANK, 0);

// Set our viewport to be the same size as the screen
glViewPort(0,0,255,191);

// Specify the Clear Color and Depth
glClearColor(0,0,12);
glClearDepth(0x7FFF);

//PA_Init3D();

if (m_bFirstLaunch)
   LoadGLTextures();

if (m_bFirstLaunch)
   m_bFirstLaunch = false;

//PA_Init3D();
//PA_LoadTexture(texture[0],(u8*)BG_DOWN_pcx, texPCX);
//PA_LoadTexture(texture[1],(u8*)cube_pcx, texPCX);
}

//affiche la scene
void DrawGLScene()
{
// Reset the screen and setup the view
glReset();
gluPerspective(35, 256.0 / 192.0, 0.1, 100);
glColor3f(1,1,1);

glPolyFmt(POLY_ALPHA(31) | POLY_CULL_NONE | POLY_FORMAT_LIGHT0);
glLight(0, RGB15(31,31,31) , 0, floattov10(-1.0), 0);

glMatrixMode(GL_TEXTURE);
glIdentity();

glMatrixMode(GL_MODELVIEW);
glLoadIdentity();

glMaterialf(GL_AMBIENT, RGB15(16,16,16));
glMaterialf(GL_DIFFUSE, RGB15(16,16,16));
glMaterialf(GL_SPECULAR, BIT(15) | RGB15(8,8,8));
glMaterialf(GL_EMISSION, RGB15(16,16,16));

glMaterialShinyness();

Test3DKeys();

RenderFond();
RenderCube();

glFlush();
}

//affichage de mes 2 objets : une grille et un cube
void RenderCube()

glPushMatrix();

      glTexCoord2f(0.0f, 1.0f); glVertex3f( l, l, l);
      glTexCoord2f(0.0f, 0.0f); glVertex3f( l, -l, l);

      // Left Face
      glNormal3f(-1.0f, 0.0f, 0.0f);
      glTexCoord2f(0.0f, 0.0f); glVertex3f(-l, -l, -l);
      glTexCoord2f(1.0f, 0.0f); glVertex3f(-l, -l, l);
      glTexCoord2f(1.0f, 1.0f); glVertex3f(-l, l, l);
      glTexCoord2f(0.0f, 1.0f); glVertex3f(-l, l, -l);
   }
   glEnd();
}
glPopMatrix(1);
}

void RenderFond()
{
glPushMatrix();
{
   glTranslatef(0.0f,-1.2f,-5.5f);

   glBindTexture(GL_TEXTURE_2D, texture[0]);

   //glColor3f(0.8f, 0.1f, 0.1f);
   v16 w=floattov16(5.0f);
   v16 h=floattov16(5.0f);
   glBegin(GL_QUADS);
   {
      glNormal3f(0.0f, 0.0f, 1.0f);

      glTexCoord2f(2.0f, 0.0f); glVertex3v16(-w, -h, 0);

      glTexCoord2f(0.0f, 0.0f); glVertex3v16(-w, h, 0);
   }
   glEnd();
}
glPopMatrix(1);
}

//et enfin le code pour charger les textures en mémoire
void LoadGLTextures()
{
int i=0;
for (i=0; i<2; i++)
{
   sImage pcx;

   //load our textures
   if (i == 0)
      loadPCX((u8*)BG_DOWN_pcx, &pcx);
   else if (i == 1)
      loadPCX((u8*)cube_pcx, &pcx);

   image8to16(&pcx);

   glGenTextures(1, &texture[i]);
   glBindTexture(GL_TEXTURE_2D, texture[i]);
   if (i==0)
      glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, TEXTURE_SIZE_256 , TEXTURE_SIZE_256, 0, TEXGEN_TEXCOORD, pcx.data8);
   else
      glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, TEXTURE_SIZE_128 , TEXTURE_SIZE_128, 0, TEXGEN_TEXCOORD, pcx.data8);

   imageDestroy(&pcx);
}
}

Mes textures sont bien à la bonne taille (de toute facon j'ai essayé avec d'autres tailles), et quand j'applique la 1ere texture sur les 2 objets tout est correct, mme chose si j'inverse l'ordre de chargement des textures.

Quelqu'un à une idéede où peut venir mon probleme?

Merci
