Hi,

I am new to CGAL. I have constructed a CGAL::Polyhedron_3 and now I want to compute the normal vector for each of its vertices. So I found the Polygon Mesh Processing package which happens to have a function doing exactly what I want . In the above link I found out that the second argument was of type VertexNormalMap which is a model of WritablePropertyMap. There was a link to boost libraries explaining(?) what writable property map is .

Unfortunately this is my first encounter with property maps and consequently I am a bit confused..

I also had a look at cgal's explanation of property maps page, but I did not understand much..

Could anyone suggest a way of creating the property map I need?

Best Regards,

Iason
