Hi, I am wondering how I can assign a Vector3 (eg. float val[3] or float x,y,z) to a property in a graph that is read in from a graphml xml file. I can easily set 3 properties, x,y,z but then I have to create a graph that is read like this: typedef property<vertex_x_t, float> x_coord_t; typedef property<vertex_y_t, float, x_coord_t> y_coord_t; typedef property<vertex_z_t, float, y_coord_t> coord_t; typedef adjacency_list<vecS,vecS,directedS, coord_t, property<edge_weight_t,float> > graph_t; graph_t g; dynamic_properties dp; dp.property("x",get(vertex_x_t(),g)); dp.property("y",get(vertex_y_t(),g)); dp.property("z",get(vertex_z_t(),g)); dp.property("weight",get(edge_weight_t(),g)); std::ifstream ifile(path.string().c_str()); read_graphml(ifile, g, dp); I would much rather be able to set a property of type Vector3 and not have to convert from the above code to a new graph whose vertices have Vector3 properties attached. thanks.
