CloudCompare forum

Hi,
I have an issue with C2C Registration. Its the second time it happens to me, so i will explain:
I built two models of a rock using two types of camera. If I change the RMS difference to a value less than 10^-8 it causes a bug that makes one of the two clouds disappear!
I tried to save in an other format and also in an other file to reopen and see whats happening but, apparently, it causes the "disparition" of at least one of my clouds!

Interesting.

Do you let the ICP algorithm 'scale' one of the cloud? If yes then maybe the scale tends towards 0?

Anyway 10e-8 is way too small (because we are working with 32 bits floating point values and they are not that accurate). I wouldn't go below 10e-6.

Nevertheless I'll try to reproduce this on my side and fix the bug ;)

Thank you!
