Understanding GLB and OFF Formats

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

Source Format

GLB 3D Model

model/gltf-binary

GLB (GL Transmission Format Binary) is the binary container version of glTF 2.0, packaging the JSON scene description, binary geometry buffers, and texture images into a single self-contained file. Developed by the Khronos Group, it is designed as the "JPEG of 3D" for efficient transmission and loading of 3D content. GLB supports PBR (Physically Based Rendering) materials, skeletal animation, and morph targets.

Advantages

  • Single self-contained file with geometry, textures, and materials
  • Optimized for fast loading in web browsers and real-time 3D applications
  • Supports PBR materials, skeletal animation, morph targets, and scene hierarchy

Limitations

  • Relatively newer format with less support in legacy 3D software
  • Binary format that is not human-readable for debugging or manual editing
  • Texture compression within GLB varies across viewers and engines

Common Uses

  • Web-based 3D content delivery with Three.js, Babylon.js, and WebXR
  • AR and VR application 3D asset distribution
  • Real-time 3D visualization in e-commerce and product configurators

Target 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
