What is OBJ file?

The file extension OBJ marks 3D model data in Wavefront format. It is a 3D data format developed by Wavefront Technologies (now part of Autodesk) for its Advanced Visualizer in the 1980s. The OBJ format is an open format and is often used today as an exchange format because it can read and write many 3D programs. Some programs like AutoDesk AutoCAD, Dassault Systèmes SolidWorks, Google SketchUp or TrueSpace (luuv plugin) require a plugin to process OBJ files.

More info

OBJ is an ASCII based format and can include 3D model data as well as material references defined in an associated mtl file. Unfortunately, the export functions of some 3D applications are limited in that they can not export all their own geometric descriptions to OBJ and often can not read all data types (eg The Materials).
