Wavefront 3D Object (.obj)
The OBJ (Object) file extension, related to Wavefront 3D Object, is a standard 3D image format developed by Wavefront Technologies. It is widely used for representing 3D geometry, including the position of vertices, texture coordinates, and normals. OBJ files are versatile and commonly employed in various CAD, 3D printing, and computer graphics applications due to their simplicity and compatibility with numerous 3D modeling programs. Introduced in the 1980s, the OBJ format has become a cornerstone in the industry, facilitating easy exchange and rendering of 3D models across different platforms.
