This line set the homogeneous IJK coordinates incorrectly: pointsDataCoords.emplace_back(bounds[1], bounds[3], bounds[5], 0.); The problem is that the last component is set to 0 instead of 1 (the coordinates specify a direction vector and not a position). When this vector is multiplied by the homogeneous transformation matrix, the position is incorrect, because the translation component of the matrix is not taken into account. fixes https://github.com/Slicer/Slicer/issues/8301 fixes #19447
