Hello,

You must use the named parameter edge_is_constrained_map      to pass eif to the  isotropic_remeshing()  function

Best,

Andreas

hello.  I follow this example,but full of bumps and hollows;

CGAL 5.4.1 - Polygon Mesh Processing: User Manual

this is my code

std::vector<edge_descriptor> border;

PMP::border_halfedges(faces(mesh), mesh, boost::make_function_output_iterator(halfedge2edge(mesh, border)));

typedef boost::property_map<Mesh, CGAL::edge_is_feature_t>::type EIFMap;

EIFMap eif = get(CGAL::edge_is_feature, mesh);

PMP::detect_sharp_edges(mesh, 60, eif);

int sharp_counter = 0;

for (edge_descriptor e : edges(mesh))

if (get(eif, e)) 

{

border.push_back(e);

++sharp_counter;

}

主题: Re: [cgal-discuss] how to subdivision without changing shape

        You can remesh a model using the following function:
        
https://doc.cgal.org/latest/Polygon_mesh_processing/group__PMP__meshing__grp.html#gad3d03890515ae8103bd32a30a3486412
        
        Note that you will probably need to detect sharp feature to be
        sure to 
        have them in the output:
