CloudCompare forum

Hi guys,

I've been trying to use the command line to merge a heap of clouds but i've been getting some weird effect. I eventually just tried opening a cloud and saving it again with the command line and i still get the same problem.
Has anyone else experienced the problem in the images below?

Before: After:

This looks like an accuracy issue... I guess your original file has very big coordinates? Does CC bothers you when you try to load the file the normal way?

In command line mode, CC won't bother the user about very big coordinates (as we try to avoid any user interaction). But it's clearly a problem here as you lose a lot of numerical precision when loading the file(s) without apply any temporary shift. Not sure how to handle that in the command line mode though... Maybe using a flag to tell CC to try to handle this "automagically"?

Ah i thought something like that might be the case. The file does have very large coordinates, cc opens it ok but always asks for a global shift.
Is there a way to force it to shift from the command line?

I'm going to add an option to handle this via the command line mode. I'll post there a beta version as soon as it's ready.

As promised, you'll find a new (beta) version here:
(edit: links removed)

I've added an option '-GLOBAL_SHIFT' that comes right after '-O' to setup how CC should handle the global shift. It should be followed:

• either by AUTO (CC will handle this automatically)
• of by 3 values (x y z) representing the Global Shift vector to apply to the loaded entity(ies)

I've updated the wiki accordingly (http://www.cloudcompare.org/doc/wiki/in ... ommandLine)

I would like to ask how to use the command line mode. Do I need to work with the cmd console in windows or is there any specific window in CloudCompare that allows operating in command line mode while you see the results on the 3D view?

Can the label connected components tool be executed using the command line mode?

Sorry for the basic questions,

Thanks a lot,

Carlos

Yes, you have to call CC through the (windows/linux/mac OS) console.

All the commands actually implemented are listed here:

The Connected Components extraction is not implemented yet, but it would be quite easy to add it.

Thank you!!

Would it be possible to see on the 3D View the results of the operations resulting from the command line?

I mean calling CloudCompare opens the interface, but if I open a point cloud (CloudCompare -o 'whatever file'), although the command line window shows it is successful, we cannot see the point cloud loaded. I would like to use some of the commands in command line mode and working manually afterwards on the interface.

Thank you in advance,

Carlos

You could simply call CloudCompare again but without the '-o' (only the filename). It should open the GUI version of CC and automatically load the file.

It worked!

Thanks for the rapid response.

Cheers.
