<DIV><FONT face=Arial>Hi,</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Another question needs your help. The point set has
thousands of points, but the mesh only has hundreds of points. The point set
has too many points than the mesh has. Could they be registered
correctly, especially be registed non-rigidly ,such as Bspline?</FONT></DIV>

<DIV><BR><FONT face=Arial>Hi Yixun,<BR><BR>Yes, it is similar to that
example.<BR><BR>Note that the "Iterative Closest Point" algorithm is covered
by<BR>a patent from General Motors, that's enough reason for *NOT*<BR>using that
algorithm.<BR><BR>The use of a distance map, as suggested in the previous
email<BR>will give you faster performance than ICP, specially if your<BR>surface
has many points.<BR><BR><BR>--------<BR><BR>For anybody interested in the dark
