[Insight-users] MeshToImageFilter ???

[Julien Jomier]

Hi Jean-Baptiste,

I've implemented the IsInside() function for the itkMeshSpatialObject but
only for TetrahedronCell. You can update the code via cvs. What type of cell
are you using?

Now, you can do something like this:

  typedef itk::MeshSpatialObject<MeshType>  MeshSpatialObjectType;
  MeshSpatialObjectType::Pointer myMeshSpatialObject=
MeshSpatialObjectType::New();
  myMeshSpatialObject->SetMesh(myMesh);

  typedef itk::Image<float,3> ImageType;
  typedef itk::ImageFileWriter<ImageType> WriterType;
  typedef itk::SpatialObjectToImageFilter<MeshSpatialObjectType,ImageType>
FilterType;

  FilterType::Pointer filter = FilterType::New();
  filter->SetInput(myMeshSpatialObject);
  filter->Update();
  
  WriterType::Pointer writer = WriterType::New();
  writer->SetInput(filter->GetOutput());
  writer->SetFileName("e:/mymesh.mha");
  writer->Update();

Let me know if you have any problem.

best regards,

Julien
