Terrain Navigation mode

[CRONOS]

I use CloudCompare very often and like it.
However, if you often jump back and forth between different cloud programmes, it is sometimes difficult to navigate.
I find it particularly difficult to navigate in CloudCompare.

One mode that can be set in Metashape, for example, is "terrain mode".
Then only the X/Y axis is shifted and it does not tilt constantly.
For free forms this might not be so good, but if you only work with flat or perpendicular surfaces it is much faster.

Is it very complex to integrate something like this?
(Or also to change the mouse button assignment. A configuration for a uniform control between my programmes would be very helpful!)

So maybe the 'Display > Lock rotation about an axis' option might help you? (you can lock the Z axis in your case).

And for the mouse buttons assignment, I don't think there's a standard among 3D tools indeed. But since CC is open-source, any motivated developer can add such an option ;)

Thanks for the quick answer!

Unfortunately, locking the axle doesn't help.
It is difficult to explain.
Maybe I will make a video soon.

When the Z axis is locked I can no longer swing up/down.
(Why are there actually numerical values and no option fields?)

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.

Ok, here are the examples.
I think you can see that it runs faster and more intuitively in Metashape.

How does it work if the cloud is not aligned with the XY plane?

But I guess it would be interesting to add this navigation mode as an option. And since CloudCompare is open source, anyone can do it ;)

[CRONOS]

Almost all geocoordinates define the terrain surface with X/Y.
And I know that a lot of people work with geocoordinates.
(Otherwise CloudCompare would not need the internal coordinate shortening. Local coordinates could be shorter).

I thought that you could "only" participate in plug-ins.
Navigation is a basic function. (And unfortunately my programming skills are not good enough).

But thank you for the answer!

[daniel]

If we need this Global Shift, it's because CC was not intended to be used with geocoordinates initially ;).

Anyone can participate to the project of course. And we really need contributors, otherwise we can't answer all the requests from users (see https://github.com/CloudCompare/CloudCo ... C/TODO.txt if you want an idea of how many of them are in the backlog...)

Hi all. If I could I would like to vote for this function. It's really hard to navigate/rotate without tilt. I usually work with Faro SCENE, where "terrain mode) is by default, but many apps has this king of navigating as default, for example Potree, Cyclone from Leica, RealityCapture and so on.
Maybe there is someone who know how to implement this, because CloudCompare is great tool, and can be even better with this.
