AW: [vtkusers] How to transform the GetOutput of vtkCutter to 2Dimage?

[Chunyan Jiang]

Stefan,
Thank you for your suggestion. I also plan to use vtkImageReslice to realize
it. However, I only have one plane including its normal and origin. I want
to use this plane to slice the volume. How should I set
SetResliceAxesDirectionCosines()? Is there some easy way to do it?

For extracting volume slices, vtkImageReslice is the approriate class.
It allows you to extract an arbitrary slice from a volume and has a
vtkImageData output. Just have a look at the documentation. Hope this
helps.

Sample code for slice in in x/y/z direction:

double position = 64.0; // Slice position
int axis = 0; // Axis

pImageReslice->SetResliceAxesOrigin(position);

if (axis == 0)
{
      pImageReslice->SetResliceAxesDirectionCosines(0.0,0.0,1.0,
                                                  0.0,1.0,0.0,
                                                  1.0,0.0,0.0);
}
else if (axis == 1)
{
      pImageReslice->SetResliceAxesDirectionCosines(1.0,0.0,0.0,
                                                  0.0,0.0,1.0,
                                                  0.0,1.0,0.0);
}
else if (axis == 2)
{
      pImageReslice->SetResliceAxesDirectionCosines(1.0,0.0,0.0,
                                                  0.0,1.0,0.0,
                                                  0.0,0.0,1.0);
}
