OBJ2GLTF

Convert OBJ assets to glTF 1.0.

Getting Started

Install Node.js if you don't already have it, and then:

npm install --save obj2gltf

Using obj2gltf as a library:

var obj2gltf = require('obj2gltf');
var convert = obj2gltf.convert;
var options = {
    embedImage : false // Don't embed image in the converted glTF
}
convert('model.obj', 'model.gltf', options)
    .then(function() {
        console.log('Converted model');
    });

Using obj2gltf as a command-line tool:

node bin/obj2gltf.js model.obj

node bin/obj2gltf.js model.obj model.gltf

node bin/obj2gltf.js -i model.obj -o model.gltf

node bin/obj2gltf.js -i model.obj -o model.gltf -s

Usage

###Command line flags:

Flag Description Required
-i Path to the input OBJ file. Yes
-o Directory or filename for the exported glTF file. No
-b Output binary glTF. No, default false
-s Writes out separate geometry/animation data files, shader files, and textures instead of embedding them in the glTF file. No, default false
-t Write out separate textures only. No, default false
--ao Apply ambient occlusion to the converted model. No, default false
-h Display help No

Build Instructions

Run the tests:

npm run test

To run JSHint on the entire codebase, run:

npm run jsHint

To run JSHint automatically when a file is saved, run the following and leave it open in a console window:

npm run jsHint-watch

Running Test Coverage

Coverage uses istanbul. Run:

npm run coverage

For complete coverage details, open coverage/lcov-report/index.html.

The tests and coverage covers the Node.js module; it does not cover the command-line interface, which is tiny.

Generating Documentation

To generate the documentation:

npm run jsdoc

The documentation will be placed in the doc folder.

Debugging

  • To debug the tests in Webstorm, open the Gulp tab, right click the test task, and click Debug 'test'.
  • To run a single test, change the test function from it to fit.
