I made a walking animation based on Biped in 3ds Max. Program MeshView animate my model properly. But my program is not. In my program mesh of Biped separated. Biped is motion and mesh at a standstill. I am insert my animation in the example of the SDK SkinMesh - everything works. Also in my program put mesh Tiny - everything works too. And mesh motion and Biped but in my program motin only Biped. In what could be the problem? My animation code made on the basis of article http://www.gamedev.net/reference/articles/article2079.asp

Just for clarification, is your "animation" in DirectX x-file format?

Also, when you say the "Biped" moves, but not the mesh - is "Biped" the bone/joint structure of your model?

If the SDK SkinMesh properly displays tiny.x and yourModel.x, then you can compare your program to the SDK example to make sure they handle the loading and animation similarly.

Thank you for your reply. I tried to compare their program with SkinnedMesh from the DirectX SDK but my level of knowledge is not high enough to understand that in this example. It is for me without assistance - very vague. My animation file was indeed converted 3dS Max X file in DirectX.

How about the question:

Quote:when you say the "Biped" moves, but not the mesh - is "Biped" the bone/joint structure of your model?

I emphasize that because, if the joint/bone structure moves and the mesh does not, it implies that you're not properly accessing the skin info data which determines which vertex indices are associated with each bone.

If you don't fully understand how to animate an x-file, then, if the SDK example works for your model, you can use that example as the basis for your program, eliminating code you don't need. There is absolutely nothing wrong with modifying existing code that works!

My program same SkinnedMesh program except that I do not use the function ConvertToBlendedMesh () - may be the reason?

You should use the ConvertToIndexedBlendedMesh method of the skin info pointer.

I added CAllocateHierarchy:: CreateMeshContainer () line

pMeshContainer->MeshData.pMesh->GetAttributeTable(NULL, &pMeshContainer->NumAttributeGroups);

delete[] pMeshContainer->pAttributeTable;
pMeshContainer->pAttributeTable = new D3DXATTRIBUTERANGE[pMeshContainer->NumAttributeGroups];


pMeshContainer->MeshData.pMesh->GetAttributeTable(pMeshContainer->pAttributeTable, NULL);

biped and mesh and steel correctly. But they are motionless, standing still. I draw them a code of CModel:: DrawFrame (LPFRAME pFrame)

for (int iAttrib = 0; iAttrib < pMeshContainer->NumAttributeGroups; iAttrib++)
{
m_pd3dDevice->SetMaterial(&pMeshContainer->pMaterials9[pMeshContainer->pAttributeTable[iAttrib].AttribId]);
m_pd3dDevice->SetTexture(0, pMeshContainer->ppTextures[pMeshContainer->pAttributeTable[iAttrib].AttribId]);
pMeshContainer->MeshData.pMesh->DrawSubset(pMeshContainer->pAttributeTable[iAttrib].AttribId);
}
pMeshContainer = (LPMESHCONTAINER)pMeshContainer->pNextMeshContainer;
}

if(pFrame->pFrameSibling)
DrawFrame((LPFRAME)pFrame->pFrameSibling);

if(pFrame->pFrameFirstChild)
DrawFrame((LPFRAME)pFrame->pFrameFirstChild);

hello Buckeye! you inspired me to look! I have got. I took the code from SkinnedMesh inserted into your project. Short, enjoyed ConvertToBlendedMesh (). But I am have another question. I issued Error on line that I marked, though in a similar line below does not give Error. What is the matter?
