Sorry, I mean pos[2] in the code, not pos[3].

The problem is still there. I am very confused why just pos[3] is not correct. If anyone of you have experienced the similar problem, please share your idea with me. I would appreciate a lot!
Thanks

Dear Users,
I am trying to get world position by SeedRepresentation->GetSeedWorldPosition(I, pos). But comparing with other software, I got the wrong value in z coordinate. The values of x and y coordinates are correct. I would appreciate if anyone can point me in the right direction.
Thanks,
Yang
