## What it is
A Node.js tool and library that converts Wavefront OBJ 3D model assets to glTF 2.0, supporting both .gltf and binary .glb output. It handles material conversion from Blinn-Phong to PBR metallic-roughness, specular-glossiness, and unlit shading models.

## Use cases
- convert obj model to gltf
- convert obj to glb binary
- prepare 3d models for web viewing
- convert mtl materials to pbr
- batch convert 3d assets for cesium
- use obj2gltf as a node library

## When to choose
- you need OBJ models in glTF/glB format for web or 3D Tiles pipelines
- you want a CLI or Node.js API for conversion
- you need material conversion between Blinn-Phong and PBR shading models

## When to avoid
- your source model is FBX, DAE, or another format rather than OBJ
- you need a GUI-based conversion tool
- you need lossless material fidelity from traditional OBJ materials to PBR
