About the OBJ file format
Wavefront OBJ
The Wavefront OBJ format has been a de facto interchange standard since the 1990s. It stores vertex positions, normals, texture coordinates, and faces in plain text, with materials described in a companion .mtl file.
OBJ does not support animation or scene hierarchies, which keeps it simple and portable across many modeling, printing, and rendering tools.
