Understanding OFF and PLY Formats

Learn about the source and target file formats to understand what happens during conversion.

Source Format

OFF 3D Model

application/x-off

OFF (Object File Format) is a simple plain-text 3D model format that stores polygon meshes as lists of vertices and face definitions. It was developed at Princeton University and uses a minimal header followed by vertex coordinates and face indices. OFF is commonly used in computational geometry research and academic settings due to its simplicity.

Advantages

  • Extremely simple format that is trivial to parse and generate
  • Human-readable plain-text representation of polygon meshes
  • Standard format for many computational geometry research datasets

Limitations

  • No support for normals, textures, materials, or colors in the basic format
  • Not widely supported by commercial 3D software or game engines
  • Plain-text format results in large files for complex models

Common Uses

  • Computational geometry research and algorithm benchmarking
  • Academic 3D model datasets and mesh processing
  • Simple polygon mesh interchange in educational contexts

Target Format

PLY 3D Model

application/x-ply

PLY (Polygon File Format or Stanford Triangle Format) is a flexible 3D model format designed for storing data from 3D scanners, supporting per-vertex properties like color, normals, and custom attributes. It was developed at Stanford University and supports both ASCII and binary encoding. PLY is particularly common in 3D scanning, point cloud processing, and computer graphics research.

Advantages

  • Flexible per-vertex property system supporting color, normals, and custom attributes
  • Both ASCII and binary formats available for readability or compact storage
  • Standard format for 3D scanned data and point cloud datasets

Limitations

  • No support for textures, materials, animation, or scene hierarchy
  • Less widely supported by game engines and web 3D viewers than OBJ or glTF
  • No standard compression, leading to large files for dense meshes

Common Uses

  • 3D scanning output and point cloud data storage
  • Computer graphics research and academic datasets
  • Photogrammetry and LIDAR data processing
