Wrong coordinates from 2d slices into 3d volume to 2d
I get the volume [0..80,0.80,0,80] and i cut it into slices and i get the
points in vtk coordinates but when i want to draw the points over the volume
i see the volume is smaller than the 2d slices.
Should i multiply each x* size of the volume_x / size_x in the 2d slices ?
