UI: Non-intuitive in how to set the Up direction

[fasteinke]

At one stage I thought I had a handle on this, but latest build is stymying me, completely. Load a ply which happens to be orientated 'wrongly', and all efforts to establish a stable, horizontal ground plane fail - the 3-point align no longer works as it used to, and I have no idea how to action it, currently.

Right, have finally worked out how to get the 3-point align to operate, a combination of LMB and MMB - would be handy to have such noted somewhere ...

Next trick: have the exact realignment be in effect for a number of plys; so that, say, different trainings of a particular dataset can be easily compared.

Sometimes the 3-point align works well; other times, one fiddles and fiddles with it, to try and get a correct Up direction ... probably too late now, but other methods, of showing current alignment in some manner and then using simple arrow key clicks to rotate and get it spot on, are more reliable, IME ... just a thought.

My captures are consistently rotated "wrong", and I usually align them by selecting the model in the scene hierarchy, then using the rotation tool, and then rather than using the gizmo with my mouse, I just type in the right-hand side-bar under Rendering tab at the top, where it shows rotation values. In my case I type in -90 on the Z. Would be handy to have a somewhat faster way to deal with this though, like selecting the "up" axis. Hope it helps you
