Nope :(

Currently this is not possible. One would have to modify the code to allow for multiple selection (I know Luca Penasa had some ideas to do this, if you are a developer or know one I could give you some pointers).

You could/should use the octree. But you'll have to dig in the code to understand how it works.

There's especially a 'cylinder' search with the octree that should help you (see CCLib's "DgmOctree").

Not sure to understand: do you mean programmatically? If yes, then you can of course scan the whole point cloud anytine (by using ccPointCloud::getPoint(i) for instance). And if you want to do that after a point click, you'll have to "listen" to the point click (by registering to the picki...

I would use the C2C (cloud-to-cloud) or C2M (cloud-to-mesh) tools? (see http://www.cloudcompare.org/doc/wiki/in ... #Distances)

Yes, sadly as CloudCompare handles "generic" point clouds, it cannot retain all the specifics of E57 files. There might be some things that could be enhanced (like the sensor position and orientation that are necessary to create a bubble view I guess). But this require some development wor...

Have you tested what format CC outputs? If it's not the one you are looking, then in the default GUI version you won't find any option to change it. Of course you could try to hack the code of the "I/O filter" that does the export job... But I'm not the author so I don't know what it impli...

Sorry for the delay, I was travelling. Assuming the cloud dimension is not longer than several hundreds of meters, you will indeed keep cm. accuracy without applying the Globlal Shift as suggested by CC. But you will definitely lose some information, which is a consequence that always needs to be ba...

Hum, interesting... Can you share the cloud with me maybe? (admin [at] cloudcompare.org)

Hum... I can't remember ;)

Just to be sure you should export the cloud (with the 'empty cells' option at 'leave empty') and check that the number of resulting points against the size of the grid (W * H). Just to be sure ;)
