Target Camera Eye/Target setting issue

11 October 2017 06:28
Hi,
User can rotate/zoom the object by using blender's default camera control
I am developing web app function that user can bring the object to the default view anytime they want.
I using "target_set_trans_pivot" to achieve that.
It usually works but from a certain camera view, it goes to flipped view rather than original view.
I checked camera's rotation, view, target value and all of them looks okay.
Could you please figure out the solution of this?
Please refer picture attached.

Hi,
The camera keeps the orientation of its UP-axis, so if it's already flipped from a particular view, then it'll also be flipped after such transformation. You should use the correct_up method to strictly define the camera orientation:
m_cam.target_set_trans_pivot(...);
m_cam.correct_up(camera, m_util.AXIS_Z, true);

Hi,
Thanks. I was able to fix the issue by initiating correct_up at the start of camera animation or end of the animation.
However, I wasn't able to avoid hard flipping animation at when I initiate correct_up. It would be best if I can
1] Fix the camera orientation all the time
otherwise
2] Make the flip (caused by correct_up) as continuous animation rather than abrupt flip

Is this possible?

Justin
