OBJ to CG4 Conversion: FAQ

What are OBJ files?

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.
