Hi Miri,
to represent fiber tracts we use mitkFiberBundleX. This datastructure is
simply initialized using a vtkPolyData containing all your fiber data.
Simple example:
vtkSmartPointer<vtkPolyData> fiberPolyData =
vtkSmartPointer<vtkPolyData>::New(); // the input datastructure for
mitkFiberBundleX
vtkSmartPointer<vtkCellArray> fiberContainer =
vtkSmartPointer<vtkCellArray>::New();
vtkSmartPointer<vtkPoints> pointContainer =
vtkSmartPointer<vtkPoints>::New();
for (int l=0; l<numlines; l++) // iterate over fibers
{
vtkSmartPointer<vtkPolyLine> fiber =
vtkSmartPointer<vtkPolyLine>::New();
for (int p=0; p<pointsInLine; p++) // iterate over points in fiber
{
vtkIdType id = pointContainer->InsertNextPoint(yourPoint);
// add next point
fiber->GetPointIds()->InsertNextId(id); // add point id to fiber
}
fiberContainer->InsertNextCell(fiber); // add fiber to fiber
container
}
fiberPolyData->SetPoints(pointContainer);
fiberPolyData->SetLines(fiberContainer);
mitk::FiberBundleX::Pointer fiberBundle =
mitk::FiberBundleX::New(fiberPolyData);

Hi All,
How I should convert my fibers which is represented in .mat file in
order to be represented on mitk view?
i.e., I'd like to view my data as :
http://www.dkfz.de/de/mbi/images/neuro3.jpg
Note that my .mat file consists of [n] number of fibers which each
fiber [i] consists of number of points [j] like this:
fibers[n]
|
|__fiber-i__
|
|___point-j(x,y,z)
Please don't hesitate to ask if a further explanation is required ...
Anyway, any information/ method would be very appreciated!
Miri
