In fact, the offset between points and texture comes from the fact that libfreenect couldn't give me the internal Kinect calibration information at that time. So I used the 'standard' information that can be found on the web. I don't know if there is a better way to do this now.

Oh, Interesting! In fact, this plugin is still a "work in progress" (to tell the truth, I almost forget about it ;). So if it has ever been released in the official version, it was an error. Or did you simply get it from the sources? I never had the time to fully test it, and I was also wo...

Actually, you won't be able to get anything more from the ccViewer command line (as it its meant to be a very simple viewer, with as less features as possible). CloudCompare's command line is being currently enhanced (in order to be able to call some of its algorithms in batch process) but it's stil...

Hello Thomas, very interesting suggestions: - you can already pick up 3 points in a interactive way, but it's meant to get the angle between them. We could of course give the normal (but as you say, it's not very interesting) - the algorithm to fit a LS plane to a set of points already exists in Clo...

Hi Dimitri, in fact the 2nd and 3rd sliders (saturation) are absolute values because they are symmetrical. Normally , if you set min saturation to e.g. 200 and max saturation to 500, the colors should be constant between [-2048;-500[ (blue), ]-200;200[ (green) and ]500;2048] (red). And inbetween it ...

I was waiting for updates about this functionnality from dktrudgett (who was willing to advance on this topic).

I might do it myself soon however.

Hello Dimitri,

Indeed it crashes in the last version! Damn, as soon as you change something somewhere, there's always another thing somewhere else that goes wrong ... I really need to build up automatic non-regression tests (but this is soooooo boring).

It's corrected (Version: 04/14/2011).

You'd best look directly at 'qCC\fileIO\BinFilter.cpp (the 'saveToOpenedFile' and 'WriteListHeader' methods). the content is as following: [4 bytes - unsigned int] the number of clouds stored in the file then for each cloud: [4 bytes - unsigned int] the number of points in the cloud [1 byte - unsign...

Hello,

in fact, people generally import their own data from an ASCII file (one point per line - 'x y z' coordinates in clear text). Once loaded, they can save it in 'bin' format to make smaller files and faster loading.

However, you'll find in attach such a 'bin' file.

Hello, CloudCompare (in fact CCLib) is actually used for clash detection in at least one project to my knowledge. It's an ongoing project at EDF R&D. The aim is to detect clashes between static structures (represented by triangular meshes or point clouds) and a moving object (generally represent...
