An OFF file, short for Object File Format, is a plain-text file used to represent the geometry of a three-dimensional object. It serves as a simple and widely-used format to store the spatial information of a 3D model. The OFF file format is not restricted to any specific software or application, making it highly versatile for exchanging geometric data among various 3D modeling and visualization tools.

Typically, an OFF file begins with a header line containing the keyword "OFF" and the number of vertices, faces, and edges in the model. The subsequent lines list the coordinates of each vertex, specifying their 3D positions in space. After that, the faces of the object are defined, where each face references a set of vertex indices that form a polygonal face. The simplicity of the OFF format makes it easy to parse and manipulate, which has contributed to its popularity in computational geometry and computer graphics research.

Despite its ease of use, the OFF file format does have some limitations. Notably, it does not support material properties, color information, or texture mapping, focusing solely on geometric representation. Additionally, it does not include any information about the topology or connectivity of the object. Nevertheless, due to its straightforward structure and widespread acceptance, the OFF file format remains a fundamental and valuable tool for sharing 3D model data across different applications and platforms.

An OBJ file is a widely used file format in 3D computer graphics that serves as a standard representation for 3D models. It stands for "Object" and was originally developed by Wavefront Technologies. OBJ files store geometric data, such as vertex positions, normals, texture coordinates, and face information, describing the surface of a 3D object. This data is presented in plain text, making OBJ files human-readable and easy to exchange between various 3D modeling and rendering software.

The structure of an OBJ file is based on vertices (points in 3D space), which form the building blocks of the 3D model's shape. These vertices are organized into faces, typically triangles or quads, representing the surfaces of the object. Alongside the geometric data, OBJ files can also include material information, enabling the application of textures and shaders to the 3D model, providing it with color, reflectivity, and other visual properties.

Due to its simplicity and compatibility across different software platforms, the OBJ file format has become a popular choice for sharing 3D models. However, being a relatively basic format, OBJ files may not support complex features found in more advanced formats like animation data or high-level shader definitions. Despite this limitation, OBJ remains a widely adopted format in various industries, including gaming, animation, virtual reality, and 3D printing.

Information for converting from OFF to OBJ

Your OFF file will be converted to a OBJ file using our unified 3D model and mesh conversion tool. Our OFF 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals and relevant material information. As OFF supports color materials and OBJ does not, our tool will not attempt to transfer any color information, your final 3D model will contain geometry data only.
