The main function for exporting a .obj file according to the given export_parameters. It uses the context C to get the dependency graph, and from that, the Scene. Depending on whether or not export_params.export_animation is set, it writes either one file per animation frame, or just one file. Central internal function to call Scene update & writer functions.

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 graphdepsgraph, 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.

Given an invalid face (with holes or duplicated vertex indices), turn it into possibly multiple faces that are valid.

Parameters
vert_coordsPolygon's vertex coordinate list.
face_vert_indicesA face's indices that index into the given vertex coordinate list.
Returns
List of faces with each element containing indices of one face. The indices are into face_vert_indices array.
