Supports OBJ files with MTL and texture files (PNG, JPG, etc.)
OBJ (or .obj) is a geometry definition file format first developed by Wavefront Technologies. It's one of the most widely used and supported 3D model formats in the industry.
An OBJ file contains several key elements:
OBJ files are often accompanied by MTL (Material Template Library) files that define the visual appearance of the model, including colors, textures, and reflectivity properties.
The format is valued for its simplicity and universal compatibility, making it ideal for exchanging 3D models between different software applications and platforms.
The OBJ file format dates back to 1989 and was one of the first widely adopted 3D model formats in the computer graphics industry.
Despite being over three decades old, it remains relevant because of its human-readable ASCII structure, which allows developers to debug models by simply opening the file in a text editor.
This accessibility made OBJ particularly valuable during the early days of 3D graphics when specialized tools were limited.
Interestingly, NASA has used OBJ files to share 3D models of Mars terrain captured by rovers, allowing space enthusiasts worldwide to explore Martian landscapes on their computers.
The format's longevity is remarkable in an industry where technological standards often become obsolete within years.
What makes OBJ technically fascinating is its elegant simplicity. Each line in an OBJ file begins with a specific identifier: "v" for vertex coordinates, "vt" for texture mapping coordinates, "vn" for normal vectors, and "f" for faces.
This straightforward structure allows for efficient parsing while maintaining complete 3D information.
Unlike more complex formats, OBJ doesn't store scene hierarchies, animations, or cameras—focusing purely on geometry and appearance. This specialization is both its strength and limitation.
The companion MTL files use a similar line-by-line structure to define materials with properties like ambient, diffuse, and specular colors.
Together, they create a remarkably complete yet understandable representation of 3D objects that has withstood the test of time in a rapidly evolving technological landscape.
Our OBJ Viewer allows you to upload and view 3D models in OBJ format directly in your browser. You can rotate, zoom, and inspect models from all angles without needing specialized software.
OBJ (Wavefront Object) is a widely used 3D file format that stores geometric data including the position of each vertex, texture coordinates, faces, and more. It's an open format that's supported by most 3D modeling applications.
Simply upload your OBJ file using the upload button, and the 3D model will appear in the viewer. You can then use your mouse to rotate the model, scroll to zoom in/out, and right-click and drag to pan the view.
Yes, your 3D models are processed entirely in your browser. We never upload or store your models on our servers, ensuring complete privacy and security of your intellectual property.
The OBJ Viewer is designed for viewing only. It doesn't currently support exporting to other formats or downloading modified versions of the models.
The OBJ Viewer works best on modern browsers like Chrome, Firefox, Edge, and Safari. Make sure your browser is updated to the latest version for optimal performance.
For best results, you should upload both your OBJ file and any associated MTL (material) files. The viewer will attempt to load materials and textures if they're included with your upload.
