Mesh Processing

CGAL offers a number of functions to process meshes. They are separated into helper classes as follows.
A example of how to use these helper class is as follows.
//Create the mesh.
var mesh = new Polyhedron3<EIK>(points, indices);
//Get a instance to the processing helperr class.
//Use the same kernel type (ie EIK)
var instance = MeshProcessingOrientation<EIK>.Instance;
//Perform the op you want.
instance.ReverseFaceOrientations(mesh);
A list of the helper classes and their functions is as follows.
