      Parameters
      ----------
      fname : str
          Filename to write. Must end with ".obj" or ".gz".
      vertices : array
          Vertices.
      faces : array | None
          Triangle face definitions.
      normals : array
          Normals for the mesh.
      texcoords : array | None
          Texture coordinates.
      name : str
          Name of the object.
      format : str
          Currently only "obj" is supported.
      overwrite : bool
          If the file exists, overwrite it.
      reshape_faces : bool
          Reshape the `faces` array to (Nf, 3). Set to `False`
          if you need to write a mesh with non triangular faces.
