C++ directx texture 9 mesh

Question

ok donc je peux charger un mesh parfaitement mais charger sa texture ne fonctionne pas. Je ne suis pas sûr de ce que je fais mal.
voici mon code ..

//render a single frame 
void RenderFrame(void) 
{ 
    d3ddev->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0, 0, 0), 1.0f, 0); 
    d3ddev->Clear(0, NULL, D3DCLEAR_ZBUFFER, D3DCOLOR_XRGB(0, 0, 0), 1.0f, 0); 

    d3ddev->BeginScene(); 

    d3ddev->SetFVF(CUSTOMFVF); 

    InitMatrices(); 

    D3DXMATRIX matTran; // a matrix to store the rotation for each triangle 
    D3DXMATRIX matRotz; 
    D3DXMATRIX matRoty; 
    D3DXMATRIX matRotx; 
    D3DXMatrixTranslation(&matTran, x, y, z); 
    D3DXMatrixRotationZ(&matRotz, D3DXToRadian(rz)); 
    D3DXMatrixRotationY(&matRoty, D3DXToRadian(ry)); 
    D3DXMatrixRotationX(&matRotx, D3DXToRadian(rx)); 

    d3ddev->SetTransform(D3DTS_WORLD, &(matTran * matRotz * matRoty * matRotx)); // set the world transform 

    // draw the spaceship 
    for(DWORD i = 0; i < numMaterials; i++) // loop through each subset 
    { 
     d3ddev->SetMaterial(&material[i]); // set the material for the subset 
     if(texture[i] != NULL) // if the subset has a texture (if texture is not NULL) 
      d3ddev->SetTexture(0, texture[i]); // ...then set the texture 

     meshSpaceship->DrawSubset(i); // draw the subset 
    } 

    d3ddev->EndScene(); 

    d3ddev->Present(NULL, NULL, NULL, NULL); 
} 

// cleans up Direct3D and COM 
void CleanD3D(void) 
{ 
    meshSpaceship->Release(); 
    d3ddev->Release(); // close and release the 3D device 
    d3d->Release(); // close and release Direct3D 
} 

VOID InitGraphic() 
{ 
    LPD3DXBUFFER bufShipMaterial; 

    D3DXLoadMeshFromX(L"ramiz.x", // load this file 
         D3DXMESH_SYSTEMMEM, // load the mesh into system memory 
         d3ddev, // the Direct3D Device 
         NULL, // we aren't using adjacency 
         &bufShipMaterial, // put the materials here 
         NULL, // we aren't using effect instances 
         &numMaterials, // the number of materials in this model 
         &meshSpaceship); // put the mesh here 

    // retrieve the pointer to the buffer containing the material information 
    D3DXMATERIAL* tempMaterials = (D3DXMATERIAL*)bufShipMaterial->GetBufferPointer(); 

    // create a new material buffer and texture for each material in the mesh 
    material = new D3DMATERIAL9[numMaterials]; 
    texture = new LPDIRECT3DTEXTURE9[numMaterials]; 

    for(DWORD i = 0; i < numMaterials; i++) // for each material... 
    { 
     material[i] = tempMaterials[i].MatD3D; // get the material info 
     material[i].Ambient = material[i].Diffuse; // make ambient the same as diffuse 
     D3DXCreateTextureFromFile(d3ddev, 
            L"ramiz.x" 
            , 
            &texture[i]); 
     texture[i]=NULL; 
    } 
} 

Answer 1

Tout d'abord, vous configurez toutes les textures à NULL dans votre boucle for, donc bien sûr il n'y a pas de texture à rendre!

for(DWORD i = 0; i < numMaterials; i++) 
{ 
    /* ... */ 
    texture[i]=NULL; // <--- You're setting all your textures to NULL! 
} 

aussi:

D3DXCreateTextureFromFile(d3ddev, L"ramiz.x", &texture[i]); 

La fonction D3DXCreateTextureFromFile() ne supporte que des textures de chargement de ces types de fichiers: .bmp, .dds, .dib, .hdr, .jpg, .pfm, .png,. ppm, et .tga. Vous essayez de charger des textures à partir d'un fichier .x, ce qui ne peut pas être correct.

Je pense que vous vouliez passer tempMaterials[i].pTextureFilename à D3DXCreateTextureFromFile() pour charger les fichiers de texture, non?

Here's how to properly load texture files for (simple) .x file rendering:

////////////////////////////////////////////////////////////////////////////// 
// Code snippet from http://www.toymaker.info/Games/html/load_x_simply.html // 
////////////////////////////////////////////////////////////////////////////// 

for (DWORD i=0; i<m_numMaterials; i++) 
{ 

// Copy the material 
meshMaterials[i] = d3dxMaterials[i].MatD3D; 

// Set the ambient color for the material (D3DX does not do this) 
meshMaterials[i].Ambient = meshMaterials[i].Diffuse; 

// Create the texture if it exists - it may not 
meshTextures[i] = NULL; 
if (d3dxMaterials[i].pTextureFilename) 
    D3DXCreateTextureFromFile(gD3dDevice, 
           d3dxMaterials[i].pTextureFilename, 
           &meshTextures[i]); 
}
