Paulo, thank you for your comments. You are absolutely right. The volume image indeed appears to have been rotated around world X axis for 300 degree. However, some part of the skeleton is missing and some strange artifact are generated so it is terribly wrong. Not sure why this happens. If I rotate 300 and rotate back ( -300) it is Ok, but any other rotation degree leads to similar issues.
Also, as you can see from the data provided, the image origin (0,0,0) is inside the volume but not at the geometric center of the volume, and the image origin (0,0,0) is also aligned with the world origin (0,0,0) in vtk.js rendering scene.
