Mittsu: GLTF

GLTF support for Mittsu.

Installation

Just install:

bundle add mittsu-gltf

Then require in your code:

require 'mittsu/gltf'

Usage

Currently this gem just includes an exporter. Loading GLTF files might happen at some point.

exporter = Mittsu::GLTFExporter.new
exporter.export(object, "output.gltf")

You can also write binary files for simple single-mesh models:

exporter.export(object, "output.glb", mode: :binary)

Progressive Meshes

The binary GLTF exporter can create "progressive meshes" using the proposed MANYFOLD_mesh_progressive GLTF extension. If you want to create these sort of meshes, you will need to install the mittsu-mesh_analysis gem and create a Mittsu::MeshAnalysis::ProgressiveMesh object, which you can then pass to export in the same way as above.
