It isn’t working at the moment. I’ve tried many times using your suggestion, but the image remains unflipped.
Here’s the code (I’m not very familiar with VTK, so if there’s a mistake, please correct me):
double upVector[3] = { 0.0, 0.0, 1.0 }; // Coronal up vector (z-axis)
double rightVector[3] = { 1.0, 0.0, 0.0 }; // Coronal right vector (x-axis)
m_InteractorStyleCoronal->SetXViewUpVector(upVector[0], upVector[1], upVector[2]);
m_InteractorStyleCoronal->SetXViewRightVector(rightVector[0], rightVector[1], rightVector[2]);
