Terrain Navigation mode

[C-R-O-N-O-S]

For all those who work with geodata, a terrain navigation mode, as in almost all other programs, would be very helpful.

In short, this is what is needed:
z-axis being kept vertical all the time
In other words, the Z axis should not be allowed to tilt to the "left" or "right".

The previous "free" rotation and tilting is interesting for any object that you want to view from all sides, but not for data on the earth's surface.

Example:

CloudCompare:

Metashape terrain mode.

Here is the explanation from the Metashape manual:
Object navigation mode allows for 3-axis rotation control, while Terrain navigation mode restricts control to 2-axis rotation only, z-axis being kept vertical all the time.

Fixing the z axis, which already exists in cloudcompare, is not the same.

I can't see the videos (seems they have been moved to the trash bin according to the error message?).

But anyway, I think I understand what you are talking about ;)
