Thank you so much Sebastien for your help.
I can get the vertex coordinates of the closest triangles by using:
std::cerr << "closest primitive is: " << *closest_primitive << std::endl;
which gives me the coordinates of all the three vertices constructing the
triangle, consecutively. How can I get the location of the points separately
instead of having them all together? (I guess it is an easy process, but I
am a beginner in both CGAL and C++) .
My other question is that then how can I know which points are involved with
this triangles? I mean in the same example, is there a way so I can know for
instance points a,b, and d are the ones that are making the closest triangle
to the query point without performing a search among all the points?
The closest point is a point that is not necessarily a triangle vertex,
it is the closest points on the set of triangles provided.
If you want to perform nearest neighbors queries, you should use this
package:
