Hello, I have a faulty code needed to be fixed. Could anyone lend me a hand cos i've been struggling with it for a couple of days already.... thanks What i need is to display a skinned mesh in my scene
But I just can't do it...
Here is an extract of my code

Note that I have a stack overrun in the last method. But you can ignore it for the moment. I'll give that a fix later
So you get a general picture of the flow of my engine. Please leave comments where you feel appropriate.
Thanks in advance

I have flipped another book, but I still have difficulties.
The code displays the original mesh that comes with the book fine. But can't display mine no matter how I tweak it.

the mesh loads ok (S_OK), but just no display for my own mesh
How can I check it is the world transformation problem or the camera's problem
I just assume there aren't any one-method-to-fit-all ways to do it
thanks

The code displays the original mesh that comes with the book fine. But can't display mine no matter how I tweak it.[/quote]

I think it comes from D3DXFRAME::Name.

In your ::CreateFrame() function, set Name parameter to NULL first, then do whatever you want:

HRESULT BoneHierarchyLoader::CreateFrame(LPCSTR Name, LPD3DXFRAME *ppNewFrame) { Bone *newBone = new Bone; memset(newBone, 0, sizeof(Bone)); newBone->Name = NULL; // <---- I've added this line! //Copy name if(Name != NULL) { newBone->Name = new char[strlen(Name)+1]; strcpy(newBone->Name, Name); } //Set the transformation matrices D3DXMatrixIdentity(&newBone->TransformationMatrix); D3DXMatrixIdentity(&newBone->CombinedTransformationMatrix); //Return the new bone... *ppNewFrame = (D3DXFRAME*)newBone; return S_OK; }
hth.
-R

There's no "hard", and "the impossible" takes just a little time.

Hi programci_84,

Thanks for your response. I am sorry to tell that it doesn't work as expected. Maybe some more advices for me

Just tried to contact the author for a week with no replies.... so i am totally despair
Thanks a lot

You've surrounded the draw() with a try ... catch block that silently swallows exceptions. Have you put in logging or tried removing this block? You could also look into adding additional error handling or logging in some places, for instance adding an "else" block to "if(SUCCEEDED(g_pDevice->BeginScene())".

I also see some function have no error checking, e.g. there is a call to D3DXCreateTextureFromFile that lacks error checking.

Sorry, I have changed my mind again. This time I converted my code back to the fixed pipeline (displaying the skinned mesh) and a shader displaying the static mesh
I wonder this approach would cause any strange results. Also, I have hardcoded the skinned mesh part. Letting it not have textures and having a predefined materials.
I have used another model which was proved to be correct in another application. I have cross-checked the matrix values against the program that is properly working.
Avoiding all the peculiar matrix values.... and finally I still can't see the skinned mesh. What other things do I have to take care of in my case?
Any comments are welcome!
BTW, thanks rip-off and other guys who are helping along.
I can send the program thru to the person who wishes to help too.... it isn't that big virtually (~30MB including data on VS2008)
Thanks
Jack

Things got lots easier than it seems now. Finally I got meshes displayed owing to projection/view matrices unset.
But i run into another problem. Is the mesh never animates..
I have update the animation controller with a running clock and I have updated the frame hierarchy
The mesh has the animationset ready. I can see the animationset returns 1
I have set the track descriptor as well plus SetTrackAnimationSet
What elses am I missing?
Thanks

Seems like advancetime has no effect on the transformationMatrix variable
I have cloned the animationcontroller, but the animation is not starting
I tried to use the original animation controller (not cloned) from mesh loading object, it animates.
Why CloneAnimationController won't work at all?



bool CDynamicObject::Create(LPDIRECT3DDEVICE9 pDevice, SkinnedMesh *pMesh, float fAnimSpeed)

{

	if(pMesh == NULL)

		return false;



	m_pDevice = pDevice;

	m_pMesh = pMesh;	



	if(m_pMesh->GetAnimController() != NULL)

	{

		DWORD dwNumAnimSet = m_pMesh->GetAnimController()->GetMaxNumAnimationSets();



 		LPD3DXANIMATIONCONTROLLER pAC = m_pMesh->GetAnimController();



		HRESULT hr = pAC->CloneAnimationController( pAC->GetMaxNumAnimationOutputs(), // >GetMaxNumMatrices(),//>GetMaxNumAnimationOutputs(),

                                      	pAC->GetMaxNumAnimationSets(),

                                      	pAC->GetMaxNumTracks(),

                                      	pAC->GetMaxNumEvents(),

                                      	&m_pAnimController );





		// fill up all tracks with animation sets

		for(DWORD i = 0; i < dwNumAnimSet; i++)

		{		

			LPD3DXANIMATIONSET pSet;

			m_pAnimController->GetAnimationSet(i, &pSet);



			m_pAnimController->SetTrackAnimationSet(i, pSet);

			SetTrackDesc(i, fAnimSpeed, 1.0f);



			pSet->Release();

			pSet = NULL;





		}



		// set default, ie activate first track

		SetTrackDesc(0, fAnimSpeed, 1.0f);

		m_dwDefaultTrack = m_dwLastTrack = m_dwCurrentTrack = 0;	

	}



	return true;

}

Seems like the master copy is working, when i clone it and distribute it to different objects. All the animation becomes stagnant. Any thoughts why this would happen..... Sorry for bumping this, cos this is quite urgent
What really annoying is CloneAnimationController actually works and returns with some ok value...
Thanks Jack
