Understanding OBJ and PLY Formats

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

Source Format

Wavefront OBJ 3D Model

model/obj

OBJ (Wavefront Object) is a widely used plain-text 3D model format that stores geometry including vertices, texture coordinates, normals, and polygon faces. Developed by Wavefront Technologies, it supports polygonal meshes with optional material and texture references through companion .mtl (Material Template Library) files. OBJ is one of the most universally supported 3D interchange formats.

Advantages

  • Widely supported by virtually all 3D modeling, rendering, and game development tools
  • Plain-text format that is human-readable and easy to parse or generate
  • Supports texture coordinates, normals, and material references

Limitations

  • No support for animation, rigging, or scene hierarchy
  • Plain-text format results in large file sizes for complex models
  • Material and texture information requires separate .mtl and image files

Common Uses

  • 3D model interchange between different modeling and rendering software
  • 3D printing with texture and material information
  • Game development asset pipelines and 3D content creation

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
