[Insight-users] I need help please!! DeformableMesh3DFilter

[Waltraud Henrich]

Hallo,

at 16 December I had written my problem in the mailing list.  Unfortunately
I received still no answer and I did not repair the problem .
I have a newer version of ITK and I  downloaded InsightToolkit-1.0.0 to
28.11.2002.
Where can I look for the errors? 
What are the meaning of the parameters: Stiffness, Scale,Time Step and Step
Threshold in the  ItkDeformableMesh3DFilter?
In the example itkDeformableTest.cxx it does not use these parameters. Why?
Is sufficient in such a way? 
I have tried it also without these parameters and it  does not go. 
 I tried with this parameter: 


	double m_stiff[2];
	m_stiff[0]=0.001;
	m_stiff[1]=0.04;
	
	myIndexType m_center={{SEEDX, SEEDY, SEEDZ}};
	
	Deformable3DFilterType::Pointer m_bfilter =
Deformable3DFilterType::New();
	
	m_bfilter->SetCenter(m_center);
	m_bfilter->SetStiffness(m_stiff);
	m_bfilter->SetTimeStep(0.001);
	m_bfilter->SetStepThreshold(20);
	m_bfilter->SetGradient(gradient->GetOutput());
	m_bfilter->SetInput(m_spheresource->GetOutput()); 
	m_bfilter->SetInput(initmesh);
	m_bfilter->Update();

1) I work with itkDeformableMesh3DFilter and now I get the OutputWindow.

2) When I save vtkUnstructuredGrid in a file and when I look this file I get
following:

# vtk DataFile Version 3.0
vtk output
ASCII
DATASET UNSTRUCTURED_GRID
POINTS 402 float
-1.#INF -1.#INF 1.#INF -1.#INF -1.#INF 1.#INF -1.#INF -1.#INF 1.#INF 
-1.#INF -1.#INF 1.#INF -1.#INF -1.#INF 1.#INF -1.#INF -1.#INF 1.#INF

-1.#INF -1.#INF 1.#INF -1.#INF -1.#INF 1.#IN.......etc

My problem is that in vtk2itkDouble.cxx this coordinates are #INF..

pcoordinates[0] = pp[0];
pcoordinates[1] = pp[1];
pcoordinates[2] = pp[2];

Can you tell me where the problem is?

3) I can disply my SphereSource with vtk2itkDouble. The coordinates are OK
here."

Thanks a lot.
