What is an obj file and how do I open an obj file?
The OBJ file extension is known as Wavefront 3D Object File which was developed by Wavefront Technologies. It is a file format used for a three-dimensional object containing 3D coordinates (polygon lines and points), texture maps, and other object information. It contains a standard 3D image format that can be exported and opened by several 3D image editing programs. Object files can be in ASCII format (.obj) or binary format (.mod) however does not contain color definitions for faces. Because of their format, they are human readable. It supports both polygonal objects and free-form objects. Polygonal geometry uses points, lines, and faces to define objects while free-form geometry uses curves and surfaces. Files in OBJ format can be opened with Autodesk Maya 2013, Blender, and MeshLab in Microsoft Windows, Mac OS, and Linux platforms.
