Hi Pierre, Thanks!

Okay. I mis-understood "turning the tin" earlier and also interpreted the
generated triangles as spikes. Now, I got it.

I am not having any point cloud file with cars cut out of it but I am
positive of some point clouds with buildings cut out. I would try running
the program again on such complete scene (with looser tolerance) and get
back to you with results.

Kind regards,
