Dear All,

When I display a MHD (3D Skull) file with VTK it appears in one rotation/angle(s) position. But I want that initially it will in another angle(s) position. How can I position in another angle(s) and record the transform from the initial position? And determine the RotateX, RotateY and RotateZ.  
Or any another way …

Thanks,

Luís Gonçalves

Hello,

I think what you want (get the linear transform given a starting and and an ending image) can be obtained with image registration: [Find Image Rotation and Scale Using Automated Feature Matching - MATLAB & Simulink - MathWorks 中国](https://ww2.mathworks.cn/help/vision/ug/find-image-rotation-and-scale-using-automated-feature-matching.html) . If so, I think you may need VTK’s sister library: ITK ([https://itk.org/](https://itk.org/)).

cheers,

Paulo
