OBJ is a 3D model format associated with Advanced Visualizer, a software suite developed by Wavefront Technologies. OBJ files contain geometry definitions of 3D models, including coordinates for each angular point, UV mapping data, texture information and details describing the faces of each polygon. Due to its frequent use, the OBJ format has been borrowed by other 3D graphics applications as well, and is currently seen as an industry standard.
The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter. This software is extremely efficient in managing a wide range of batch conversions. As you will soon realize, reaConverter will help you avoid spending countless hours trying to figure out how to convert multiple OBJ files as once.
