Dear all,

 

I have a set of 3d points with x, y, z values. I would like to make TIN model (Delaunay triangulation is also fine for me )out of these points and calculate the normal vector of each TIN facet with ArcObjects, better in C sharp. Does anyone have an idea how I can achieve that?

 

Kind regards

Yvan
