[Openflipper] Visualize property in a polyhedral mesh

Hello, I followed this tutorial http://www.openflipper.org/media/Documentation/OpenFlipper-1.3/ovm_tutorial_... to add properties to edges of a Polyhedral Mesh. The properties are set correctly. I can for example, iterate over all edges and print their property values. However, when I use the Property Visualisation plugin of OpenFlipper, the property I set is shown as zero for all edges.

Does someone know what is wrong?

Here it is my code:

int cur_insert_id = -1;

PolyhedralMesh* cur_volume_obj = 0;

emit addEmptyObject(DATA_POLYHEDRAL_MESH,cur_insert_id);

BaseObjectData *obj;

PluginFunctions::getObject(cur_insert_id, obj);

obj->target(false);

PolyhedralMesh* cur_polyhedral_mesh = PluginFunctions::polyhedralMesh(obj);

OpenVolumeMesh::EdgePropertyT<double> angle = cur_polyhedral_mesh->request_edge_property<double>("Edge Angles");

for(OpenVolumeMesh::EdgeIter e_it = cur_polyhedral_mesh->edges_begin();

e_it != cur_polyhedral_mesh->edges_end(); ++e_it)

{

double ang = 0;

…

angle[*e_it] = std::abs(ang);

}

emit updatedObject(obj->id(),UPDATE_ALL);

Thx very much in advance
