OFF (Object File Format) is a simple format for representing 3D geometry, primarily used in computational geometry and computer graphics research.
Key features of OFF files:
OFF files are particularly common in mathematical and computational geometry applications, 3D mesh processing research, and educational contexts where simplicity and clarity of the format are valuable.
OFF files were popularized by the Geometry Center at the University of Minnesota in the 1990s as part of their Geomview software package for mathematical visualization.
The Princeton Shape Benchmark, a standard dataset for 3D shape retrieval research, provides many of its models in OFF format.
Researchers in topological data analysis often use OFF files to represent simplicial complexes and other geometric structures critical to understanding data shapes.
OFF files are particularly popular in computational geometry courses because students can easily read and write them without specialized software.
The format is also used in some molecular visualization applications to represent molecular surfaces and protein structures.
An OFF file begins with the keyword "OFF" followed by three integers representing the number of vertices, faces, and edges (though the edge count is often ignored).
Each vertex is specified by three floating-point coordinates (x, y, z), making it easy to parse and generate programmatically.
Faces are defined by listing the number of vertices in the face followed by the indices of those vertices, allowing for representation of triangles, quadrilaterals, and other polygons.
The format supports optional color specifications using RGB values (0-255) for each vertex or face, enabling visualization of data attributes through color mapping.
While OFF files don't support textures or complex materials, their simplicity makes them ideal for algorithm development and mathematical analysis of 3D structures.
Our OFF Viewer allows you to upload and view 3D models in OFF format directly in your browser. You can rotate, zoom, and inspect models from all angles without needing specialized software.
OFF (Object File Format) is a simple geometry definition file format that specifies the geometry of an object as a list of flat polygons. It's commonly used in computational geometry and computer graphics research for representing 3D meshes.
Simply upload your OFF 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.
The viewer supports OFF files up to 50MB in size. Larger files may take longer to load depending on your internet connection speed.
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 OFF Viewer is designed for viewing only. It doesn't currently support exporting to other formats or downloading modified versions of the models.
The OFF 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.
Yes, our viewer supports colored OFF files. If your OFF file includes color information for faces or vertices, these colors will be displayed in the 3D view.
