File extension obj is used by following file type(s):

File extension obj file type 1 description:
Blender 3D object

The obj file extension is associated with Blender. The obj file format is usually a simple data-format that represents only the 3D geometry, such as the position of each vertex, the texture coordinate associated with a vertex, the normal at each vertex, and the faces that make each polygon.

Intel (Object Module Format) relocatable object module

The Relocatable Object Module Format is an object file format used primarily for software intended to run on Intel 80x86 microprocessors. It was originally developed by Intel under the name Object Module Format, and is perhaps best known to MS-DOS users as a .OBJ file. It has since been standardised by the Tool Interface Standards Committee.

File extension obj file type 7 description:
Microsoft Visual Studio object file file

The OBJ file extension is associated with Microsoft Visual Studio. The .obj files are used for object files, which are compiled but not linked.

LINK accepts .obj files that are either Common Object File Format (COFF) or 32-bit Object Module Format (OMF). Microsoft's Visual C++ compiler creates COFF .obj files.

LINK automatically converts 32-bit OMF objects to COFF. However, there are limitations to OMF to COFF conversions. OMF can represent some things that cannot be represented in COFF. If there are errors when the linker converts from OMF to COFF, then you will need to use COFF .obj files instead of OMF .obj files as input to the linker.

Windows NT uses a special format for the executable (image) files and object files. The format used in these files are referred to as Portable Executable (PE) or Common Object File Format (COFF) files. The name Portable Executable refers to the fact that executable files can run on more than one platform. This article describes in detail the internal features of PE/COFF file formats and its parameters.

Wavefront 3D object

Wavefront OBJ (object) files are used by Wavefront's Advanced Visualizer application to store geometric objects composed of lines, polygons, and free-form curves and surfaces. Wavefront is best known for its high-end computer graphics tools, including modeling, animation, and image compositing tools. These programs run on powerful workstations such as those made by Silicon Graphics, Inc.
