[ITK Community] Fwd: Points Cloud in C#

[Luis Ibanez]

Matias,

There are not many examples in C#.

One way to go is to write the process into a C++ class,
and then wrap it into C# using SWIG,
which is what SimpleITK does.

In this way you could still start from those examples.

   Thanks

        Luis
