Hello, I'm trying to add an existing TriMesh into scene but got some error. The TriMesh object is generated by myself (not by the core of OpenFlipper) to store the result of my algorithm. I would like to add it into scene but found no suitable functions. I tried to use LoadSaveInterface::addEmptyObject to create an empty TriMeshObject first and then change its underlying data using MeshObject<MeshT>::mesh(). This seems fine until I called OpenMesh::PolyMeshT<Kernel>::update_face_normals(). My debugger showed that the assertion in const PropertyT<T>& property(BasePropHandleT<T> _h) in PropertyContainer.hh failed when accessing point_ property. The point_ property is fine and I did call request_face_normals() before update_face_normals(). I also tested this mesh with TriMesh.point() and got no errors. Unlike previous case, it use static_cast so no assertion error occurs.
For dependency reason, I need to separate algorithm from UI-related codes. So I would like to avoid using LoadSaveInterface::addEmptyObject in my algorithm class. And it's not possible for me to use LoadSaveInterface::addEmptyObject before my algorithm because I don't know how many meshes will be created.
Any suggestion? Thank you.
