skeletal animation problem
Author
Hi,
I got a problem, when I load a charecter model by using directx 9,
the charecter model not load in the world origin, I have to
zoom out the camera to :
D3DXMatrixLookAtLH(&view, &D3DXVECTOR3(0.0f, 0.0f, -5000.0f), &D3DXVECTOR3(0.0f, 0.0f, 0.0f), &D3DXVECTOR3(0.0f, 1.0f, 0.0f));
D3DXMatrixPerspectiveFovLH(&proj, 0.2f, 1.33333f, 0.01f, 100000.0f);
then I can see the model but I can't see the texture, but I draw this model in local origin at 3d animation software.
I also try to load the Blender's sample model, but I totally can not see the model.
I can see the model if I opened the .x file in Directx viewer.
The original source code which I using is from the book, The author draw the model by using 3Ds Max, and can be loaded properly.
Is it the problem from the Model's .x(3d software) file or from the source code ?
Some of the source code are as below :
Thank you

If the mesh can be seen properly in the mesh viewer, then it is extremely likely that the problem is in your code.
Does your code load and display other .x files properly, like tiny.x, etc?
With regard to the texture, the code you posted has the SetTexture() line commented out.
Also, do you successfully load the texture when the .x file is loaded? If so, how do you know?

The model create using 3ds max can load successfully( position and texture).
The tiny.x can be loaded but not in origin coordinate, I have to zoom out in order to see the model and can not see the texture. Do u know how to set the model to origin position in Directx 9.
The texture code as below :

Something I notice, you have a very small fov in your perspective matrix. Your view is in an extreme "zoom" mode. You're not zooming out, you're zooming in, which makes the model appear much larger than a more normal perspective. Try setting the fov in your perspective matrix call to something a little more "normal," such as D3DX_PI/4.0f.

A previous question:
kslam: you do not test any return codes from any of your calls.
How do you know if the texture was loaded correctly?
If you don't test any return codes, then you may have many errors.
Quote:do you successfully load the texture when the .x file is loaded? If so, how do you know?

I validate the code below, the program run without error but can't see texture. (The model is red color without texture)
If I disable the VS and PS code, the model become black color.
I think this code is custom made for the 3ds Max model.
HRESULT hResult = D3DXCreateTextureFromFile(m_pDevice, textureFname, &newTexture);
if (FAILED(hResult))
{
strcpy(emsg, "Error creating texture.");
PostQuitMessage(WM_QUIT);
break;
}
-------------------------------------------------------------
HRESULT hResult = m_pDevice->SetTexture(0, boneMesh- textures[mtrlIndex]);
if (FAILED(hResult))
{
strcpy(emsg, "Error settexture.");
PostQuitMessage(WM_QUIT);
break;
}

In this loop:
you're drawing the subset with the mtrlIndex instead of the attribute group number.
That may not be the problem but you should be using:
for(int i=0;i < boneMesh->NumAttributeGroups;i++){ int mtrlIndex = boneMesh->attributeTable.AttribId; m_pDevice->SetMaterial(&(boneMesh->materials[mtrlIndex])); m_pDevice->SetTexture(0, boneMesh->textures[mtrlIndex]); boneMesh->MeshData.pMesh->DrawSubset(mtrlIndex);}you're drawing the subset with the mtrlIndex instead of the attribute group number.
That may not be the problem but you should be using:
boneMesh->MeshData.pMesh->DrawSubset(i);This topic is closed to new replies.
