OBJ (Wavefront OBJect) is a 3D printer file format that was originally used by graphics designers as a neutral interchange format for 3D graphics. It was first developed by Wavefront Technologies for its animation package. This file format has the extension . obj.
What is an OBJ file used for?
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.
What is OBJ format for 3D model?
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.
Is OBJ or STL better?
In terms of geometry description, OBJ is more capable than STL, as it can describe “real” curves, without the need to approximate them to a series of polygons.
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 use OBJ?
To import an OBJ file: Select File > Import > Import OBJ (3D only). Select the file to import, and click Open. Click OK. OBJ geometry and components are imported as specified. A mesh object is created, and it is automatically selected.
What opens an OBJ file?
Files in OBJ format can be opened with Autodesk Maya 2013, Blender, and MeshLab in Microsoft Windows, Mac OS, and Linux platforms.
Can you print an OBJ file?
However, the most popular are . STL and . OBJ files. These file formats are supported by most printing software and 3D printers.
Are OBJ files editable?
Yes, OBJ files can easily be edited. You just need to use a 3D CAD software or web service that lets you import and edit OBJ files on your PC. In this article, you can find some better free tools and software that let you modify OBJ models.
Who uses OBJ files?
The OBJ format is considered to be a universal 3D model format since it is widely supported by 3D image editing applications. The format is simple and text-based, which is one reason why many programs use it.
Is an OBJ file a mesh?
Because of its aesthetic value, it’s usually used by 3D animators and artists but since it is a watertight mesh you can use it for printing too. It offers a more realistic likeness to the object itself, vibrant color and photographic accuracy, meaning that it saves loads of CAD modeling time.
What is the difference between OBJ and FBX?
OBJ is much simpler format that only keeps geometry (vertex, normals, etc) and uv data. FBX is much more advanced format that can hold much more data – models, uv data, joints, skinning information, animations, multiple takes of animation in one file, curves, and even embed texture files.
How do I create an OBJ file?
Create an OBJ Cube With Your Favorite Images Step 2: Collect Your Desired Pictures. Step 3: Download 3D Builder. Step 4: Create a Text Document. Step 5: Add OBJ Vertices. Step 6: Add Normals and Texture Coordinates. Step 7: Add Face Related Information. Step 8: Review Your OBJ File for Errors.
Which 3D format is best?
3ds is one of the best 3D file formats when it comes to drawings and objects. Since the 3DS format is understood by virtually all 3D-related software, such files can be opened or imported with a large number of tools. The main areas of use are architecture, engineering, education, manufacturing.
What is CAD in 3D printing?
Computer-aided design, or more commonly referred to as CAD, is used to generate virtual 2D or 3D models. 2D CAD designs are generally for technical engineering/architecture, while 3D models are typically either used for digital applications such as animation or for manufacturing/prototyping processes like 3D printing.
How do I convert STL to OBJ?
How to Convert STL to OBJ with Spin 3D Mesh Converter Software Download Spin 3D Mesh Converter Software. Download Spin 3D Mesh Converter Software. Import STL Files into the Program. Choose an Output Folder. Set the Output Format. Convert STL to OBJ.
What does an MTL file do?
An MTL file is a material settings file used by 3D object editing applications, such as Adobe Photoshop and Autodesk Maya. It is stored alongside an . OBJ file and describes how a program should apply textures to that object. In this way, users can easily apply multiple textures to the same object.
Can 3DS Max Open OBJ files?
Geometry imported from OBJ files appears in 3ds Max as editable mesh or editable poly objects. From the File menu, choose Import. The Select File To Import dialog opens. Choose an OBJ file to open and click Open.
How do I change blend to OBJ?
How to Convert OBJ to BLEND Open your OBJ file in Blender using the “Open” command on the “File” menu. Alternatively, use the “Import” command to add your OBJ file to an already existing BLEND project file. Modify and improve your object using Blender’s modeling and animation tools. Save your project as a BLEND file.
How do I open a .model file?
Browse Files 1st Method: Open it in another program. When you double-click MODEL files, your computer attempts to open it in a program associated with MODEL files. 2nd Method: Take a hint from the file type. 3rd Method: Check with the developer. 4th Method: Open it in a universal file viewer.
How do I view Dae files?
How to Open a DAE File. DAE files can be opened or imported into Adobe Photoshop, SketchUp, Chief Architect, DAZ Studio, Cheetah3D, Cinema 4D, MODO, and Autodesk’s AutoCAD, 3ds Max, and Maya programs. Other applications probably support the DAE format too, like the free and open source Blender tool.
