What is in an OBJ file?
An OBJ file (. obj) contains information about the geometry of 3D objects. The files are used for exchanging information, CAD, and 3D printing. OBJ files can support unlimited colors, and one file can define multiple objects. The current version is 3.0.

How do .OBJ files work?
The OBJ file format is a simple data-format that represents 3D geometry alone — namely, the position of each vertex, the UV position of each texture coordinate vertex, vertex normals, and the faces that make each polygon defined as a list of vertices, and texture vertices.
Can Blender Open .OBJ files?
Luckily, Blender offers a wide range of file formats (e.g. OBJ, FBX, 3DS, PLY, STL, etc.) that can be used to import and export.
What is a .OBJ file C++?
C++ Object File (*. obj, *.o) Go Up to File Types Index. A C++ object file is an intermediate file produced by a C++ compiler from a C++ implementation file and the C++ header files that the implementation file includes. The C++ linker produces the output executable or library of your project from your C++ object files ...
Can AutoCAD open an OBJ file?
Right now, AutoCAD cannot read an . obj file directly. Please use Autodesk 3DS Max to create the . dwg file from the OBJ file.
What is the difference between OBJ and STL?
STL files store objects as sets of vertices joined by edges to make triangular faces. OBJ files store 3D information as a list of vertices joined by edges, and unlike STLs, they support polygonal faces that allow for a closer representation of the original geometry.

How do I open an OBJ file?
If you receive an OBJ file you can choose from a large number of free and commercial applications to open it. However, you should select the program based on the context in which the OBJ file will be used. For example, if you are looking to open and modify a 3D object utilized in film special effects and are on a tight budget, you could use the free Blender software.
Why is OBJ file so big?
The format is simple and text-based, which is one reason why many programs use it. However, the simple format structure may also lead to huge OBJ file sizes if they store large and complex 3D objects.
Is FileInfo.com accurate?
The FileInfo.com team has independently researched all file formats and software programs listed on this page. Our goal is 100% accuracy and we only publish information about file types that we have verified.
What is an obj file?
OBJ is a vector file, which makes the defined objects scalable. There’s no maximum file size.
Why are OBJ files used?
Because one of the primary uses of OBJ files is 3D printing, understanding how 3D files become 3D objects is key. At a high level, this is what happens:
What program to open an obj file?
You need a CAD or 3D graphics/modeling program to view, open, or edit an OBJ file using Windows, Mac, or Linux. Here’s a comprehensive list of software you can use to work with OBJ files.
How many ways are there to encode a surface geometry?
OBJ files have three different ways to encode the surface geometry of an object. Each method has its strengths and is good to use in various situations. Here is an overview:
When was OBJ created?
The format was created in the 1980s by Wavefront Technologies for its Advanced Visualizer animation software (Autodesk Maya has since replaced Advanced Visualizer). The file extension OBJ comes from the name Wavefront OBJect (the full name is rarely used). Other companies have adopted the OBJ format for use in their applications.
Can obj files be referenced?
OBJ files can reference vertices, normal, etc. by either absolute position or by relative position. Not all software supports both methods, so take care when opening files to ensure they are compatible with the software you’re using.
Is OBJ a large user base?
OBJ has a large user base and support system, so if that is important to you, consider using OBJ.
What is an OBJ File?
OBJ files are used by Wavefront’s Advanced Visualizer application to define and store the geometric objects. Backward and forward transmission of geometric data is made possible through OBJ files. Both polygonal geometry like points, lines, texture vertices, faces and free-form geometry (curves and surfaces) are supported by OBJ format.
History
Wavefront Technologies created OBJ file format for its Advanced Visualizer application to store geometric objects and 3D data. Its version 2.11 is superseded by a newly documented version 3. The file format is open and has been implemented by other vendors for their 3D graphics application.
OBJ File Format
In 3D objects, encoding the surface geometry is a challenging job that OBJ file format accomplished very well. This format is quite versatile as it offers a number of choices to encode surface geometry. Following are three allowed formats having their own benefits and shortcomings:
What is an obj file?
OBJ (or .OBJ) is a geometry definition file format first developed by Wavefront Technologies for its Advanced Visualizer animation package. The file format is open and has been adopted by other 3D graphics application vendors.
What is a free form geometry statement?
A free-form geometry statement can be specified in a line starting with the string vp. Define points in parameter space of a curve or surface. u only is required for curve points, u and v for surface points and control points of non-rational trimming curves, and u, v and w (weight) for control points of rational trimming curves.
Why do files contain vendor specific alterations?
Because of the ease in parsing the files, and the unofficial spreading of the file format, files may contain vendor specific alterations.
What is an object file?
An object file is just what you get when you compile one (or several) source file (s). It can be either a fully completed executable or library, or intermediate files. The object files typically contain native code, linker information, debugging symbols and so forth. Share.
How many types of object files are there?
There are 3 kind of object files.
What is an executable file?
An executable file is formed by linking the Object files. Object file contains low level instructions which can be understood by the CPU. That is why it is also called machine code. This low level machine code is the binary representation of the instructions which you can also write directly using assembly language and then process ...
How are executable files formed?
An executable file is formed by linking the Object files.
What is the process of a.c. file?
The full process would be: preprocessor ( cpp) would run over a.c. Its output (still source) will feed into the compiler (cc1). Its output (assembly) will feed into the assembler (as), which will produce the relocatable object file. That file contains object code and linking (and debugging if -g was used) metadata, and is not directly executable.
