The scene has only one volume, and the volume is from a vtkImageData structure. It looks fine under the camera rotation. When I rotate the volume, why should I rotate other objects in the scene? Also, as you can see after the rotation the bone is not complete anymore, and the artifacts are certainly generated from the volume data because of its color(just not sure how and why).
Is there any other DICOM volume image rotation example? If so it certainly helps to debug this issue.
