Cloud2Cloud distance issue

Post by zielas »

Hello,

i'm trying to compute distance between two clouds and i'm getting strange behavior.
When i try to compute distance between original clouds it's last forever (noticed that the approximate distances are huge), but when i mirror them by Y axis it's immediate.

I've attached four clouds. Couold you take a look at this and give me some clue?

Okay I found it. This was a tricky one: an ugly round-off issue due to the fact that the cloud was perfectly flat and that the internal tests were not robust to this particular case. So I changed a few things so as to never fall in the same kind of issues in the future.

Here is the corresponding version (2.5.6.beta, 64bits):

Once again, thanks for the feedback!
