CloudCompare forum

Hi Daniel,

First thank you for the software, it is really powerfull!!

I have a question, i explain my need :

I want to compare multiple point clouds to the other one automatically. To do that i use command line (because point clouds have always the same names)

My process is : import 1st point clouds -> decimate -> import 2nd PC -> decimate -> Compare 1 to 2 -> RENDER TO FILE -> export

And i don't know if the render to file command exist .. can you help me?

Thank you

You mean 'render the display to an image file'? If yes, it's not possible as the command line has no OpenGL window..

Ah ok, I said as CloudCompare is open to me, it was enough to use option Display-Render to file ... ok

I have an other trouble. My files are LAZ format, and at the import (-o XXX.laz -GLOBAL_SHIFT AUTO) i have some error message :

[load] Can't guess file format no file extension

If i click 3 times on ok, a windows Open LAS file come, i have to click on Apply to all. And CloudCompare start import.

And i have the same problem with the second point clouds. Do i have to change my point clouds format?

Weird, I'll have to check this on my side. What OS are you working with?

Windows 7 - 64 bits - CloudCompare 2.7.0

Ok wait daniel, it's not LAZ format who causing problems!

Because if i load bin files (export from CloudCompare) i have the same message.

Maybe my code is not good : "C:\Program Files\CloudCompare\cloudcompare" cloudcompare -o 01.bin -o 02.bin -c2c_dist

why the second 'cloudcompare'?

It's a good question ^o^, end of the week .... sorry

So you were not starting the command line mode in fact (CC was simply trying to load a file named 'cloudcompare', then another file named '-o' and eventually a file named 'XXX.laz' ;).

OOokk, i understand why it's not possible to create a render !! OMG, Luckily you're here !!
I'm very sorry for the disturbs ....
