Provides a Ruby extension for TinyGLTF, a C++ glTF 2.0 library.


Add this line to your application's Gemfile:

gem 'tiny_gltf'

And then execute:

$ bundle

Or install it yourself as:

$ gem install tiny_gltf


Use the same interface for loading a binary or JSON glTF file, from a file on disk or from memory:

    require 'tiny_gltf'

    str = File.read('path/to/model.gltf')
    gltf = TinyGLTF.load(str)

    binstr = File.open('path/to/model.glb', 'rb').read
    gltf = TinyGLTF.load(binstr)

    gltf = TinyGLTF.load('path/to/model.gltf')

In all forms, an optional second argument provides the path to any external resources needed by the model file. It defaults to either the path to the model (if the first argument is a filename), or '.' (if the first argument is a blob).

    gltf = TinyGLTF.load(binstr, 'path/to/assets')

The return value is an instance of TinyGLTF::Model.


After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
