std::pair< Vector< std::unique_ptr< OBJMesh > >, Vector< std::unique_ptr< OBJCurve > > > blender::io::obj::filter_supported_objects ( Depsgraph * depsgraph,

Filter supported objects from the Scene.

Note
Curves are also stored with Meshes if export settings specify so.

Find the objects to be exported in the view_layer of the dependency graphDependency Graph, and return them in vectors unique_ptrs of OBJMesh and OBJCurve. If export_params.export_selected_objects is set, then only selected objects are to be exported, else all objects are to be exported. But only objects of type OB_MESH, OB_CURVES_LEGACY, and OB_SURF are supported; the rest will be ignored. If export_params.export_curves_as_nurbs is set, then curves of type CU_NURBS are exported in curve form in the .obj file, otherwise they are converted to mesh and returned in the OBJMesh vector. All other exportable types are always converted to mesh and returned in the OBJMesh vector.
