Hi, if you add a face and get this warning, the face will not be actually added to the mesh. You will receive an invalid face handle as the return value of the add_face function. Therefore you do not have to remove anything. Regards, Jan Möbius On 10/26/23 10:41, btyukodi@brandeis.edu wrote:
The function add_face uses 3 ordered VertexHandle to add a face to the mesh. If the order of vertices is incompatible with the existing mesh (so that the face would be wrongly oriented) or a triangle already exists with those 3 vertices, this is the typical warning OpenMesh gives:
PolyMeshT::add_face: complex edge
I was wondering if it is possible to test whether a face addition would result in such complex edge warning and skip the addition if it would? I'm thinking some kind of try-catch block. Alternatively, how can I remove the face that caused such an incompatibility?
Note that here my aim is not to properly orient the new face. I simply do not want to add it if it causes incompatibilities.
Thank you and all the best, Botond _______________________________________________ OpenMesh mailing list -- openmesh@lists.rwth-aachen.de To unsubscribe send an email to openmesh-leave@lists.rwth-aachen.de https://lists.rwth-aachen.de/postorius/lists/openmesh.lists.rwth-aachen.de
