[Bf-vfx] Bundle display orientation

[François T.]

+1 for the scale of the bundles
I wouldn't be radical on the orientation though, if it can be setup in
property panel it would be nice (either if world is by default). I find it
"less confusing" and messy when looking trough the camera. Especially when
you'll get auto-track with 100 of trackers.


cheers,

F.

Camera tracking is based on camera-space, it can only give camera-space results. There's no information in video/film footage to derive where 'up' or 'down' is, or how a camera is tilted.
