@Yongun_Lee, @lassoan, @pieper,
@Yongun_Lee , did you ever solve your issue?
I’m having the same exact problem and I started with the Four Panes Viewer example recommended by many as a great starting point for performing oblique slicing.
I don’t have time to start over with another app because I need to meet a release deadline. Everything is perfect except that darn Sagittal view need to be flipped horizontally. Originally, the axial view was vertically flipped (superior on the bottom) and in the process of attempting to correct the axial orientation, The sagittal view ended up facing right. Whack-A-Mole. If I could somehow swing the camera to the other side of the body, I think that would solve it. No time to find another example to start over again. Users have high expectations and want his functionality ASAP. I think the problem might stem from the fact that for VTK’s (0 .0) origin is in the lower left corner.
I’ll keep trying things and will let y’all know if I solve this. I’ll share my app after I perfect it. Thanks.
