[vtkusers] Problems with coordinates

[Karl]

I have just recently started using VTK and may be wrong, but I believe that
all dicom data sets are opened so that the image slices lay in the xy-plane.
The directional cosines are not used to properly orientate the volume.  You
would need to manually do this yourself using the positioning, orientation,
and spacing provided in the dicom headers.

Subject: [vtkusers] Problems with coordinates


I have an app with 5 scenes containig differents representation of the same
dicoms, like axial, 3d, oblique, etc. I want to place a vtLineWidget in the
first scene and it should appear at the exatcly position it was in the first
one. If i place it in some slice at axial scene it should appear at the same
slice in 3d image for example.But i change the coords of the scenes by
getting the point1 and point2 of the line in the first scene but the
position at others are totally wrong. Anyone know why?
