[英]CGAL hole filling with color
我需要使用支持顏色的CGAL庫實現3D孔填充。
沒有修改CGAL庫,是否有可能這樣做? 我需要用孔邊緣的平均顏色填充孔。
問候,阿里
....
int main(int argc, char* argv[])
{
const char* filename = (argc > 1) ? argv[1] : "data/mech-holes-shark.off";
Mesh mesh;
OpenMesh::IO::read_mesh(mesh, filename);
// Incrementally fill the holes
unsigned int nb_holes = 0;
BOOST_FOREACH(halfedge_descriptor h, halfedges(mesh))
{
if(CGAL::is_border(h,mesh))
{
std::vector<face_descriptor> patch_facets;
std::vector<vertex_descriptor> patch_vertices;
bool success = CGAL::cpp11::get<0>(
CGAL::Polygon_mesh_processing::triangulate_refine_and_fair_hole(
mesh,
h,
std::back_inserter(patch_facets),
std::back_inserter(patch_vertices),
CGAL::Polygon_mesh_processing::parameters::vertex_point_map(get(CGAL::vertex_point, mesh)).
geom_traits(Kernel())) );
CGAL_assertion(CGAL::is_valid_polygon_mesh(mesh));
std::cout << "* FILL HOLE NUMBER " << ++nb_holes << std::endl;
std::cout << " Number of facets in constructed patch: " << patch_facets.size() << std::endl;
std::cout << " Number of vertices in constructed patch: " << patch_vertices.size() << std::endl;
std::cout << " Is fairing successful: " << success << std::endl;
}
}
CGAL_assertion(CGAL::is_valid_polygon_mesh(mesh));
OpenMesh::IO::write_mesh(mesh, "filled_OM.off");
return 0;
}
如果將CGAL :: Surface_mesh用作“網格”,則可以使用動態屬性映射來定義簡單對象的屬性,例如,可以為每個面定義顏色。 為此的“標准”語法是
mesh.add_property_map<face_descriptor, CGAL::Color >("f:color")
我認為。 Surface_mesh文檔中有示例。
