Questions tagged [.obj]

A text-based file format that stores 3d geometry.

The .obj file format was developed originally by Wavefront Technologies for their flagship 3d graphics software The Advanced Visualizer.

It is a text-based format that is human readable and simple to parse. .obj can only store the position, UV coordinates, and normal of a vertex. Mesh hierarchies and animation of any kind are not supported. Free-form geometry like curves and surfaces are defined in the specification, but are not used that often, and as a result, not commonly implemented in parsers.
