[Insight-users] about register point set with surface

[Luis Ibanez]

Hi Yixun,

Yes, it is similar to that example.

Note that the "Iterative Closest Point" algorithm is covered by
a patent from General Motors, that's enough reason for *NOT*
using that algorithm.

The use of a distance map, as suggested in the previous email
will give you faster performance than ICP, specially if your
surface has many points.
