<pre wrap="">Hi Seb,
I'm not sure how to interpret this request; but to me it seems very sane and predictable to only draw bundles inside the camera transformation. 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.</pre>

<small>Yes, there's no such information came from camera solver
directly, but it's what definitely known after you oriented camera
in scene (defining origin, floor, axis direction).</small><br>

<pre wrap="">What you do by positioning/rotating/scaling camera is to provide a mapping from 'video/camera space' into Blender's scene (world space). A user can decide to either scale or rotate the objects in a scene into the camera, or the other way around. All very basic, predictable and nice I think. :)</pre>

<small>Currently bundles are used as a "reference" to place objects
in Blender's scene, you can't actually parent something to bundle
and, anyway, if it was possible i don't think having bundles
oriented in camera space was so helpful. Look at bundles as
representation of real features -- real features are in global
space, not in camera space and usual workflow is to orient solved
camera in a way, that scene's floor respects real floor and X axis
respects some "axis" from real world and all objects placed in
scene respects things happening on the footage. That's why bundles
which are used as reference are nicer not follow camera rotation.<br>
<br>
It's not difficult to achieve and it should be more useful than
current behavior.<br>
