A plugin to upload and render glTF 3D models in WordPress.

== Description ==

WARNING: This code is pretty experimental and there are lots of breaking changes all the time. This is because WebVR and GLTF are fast-moving standards, as is the browser support for these standards, so please bear with me while the dust settles on this brave new world :)

[glTF](https://github.com/KhronosGroup/glTF) is an emerging open standard for the transmission and storage of 3D models. This plugin allows you to upload these models in "Embedded JSON" and Binary formats. Currently, inline rendering is only supported for the JSON format.

The ultimate goal of this plugin is to provide a 3D "post type" (gltf_scene) which allows the user to compose an interactive scene populated by objects that represent other content from their site (e.g. a book containing posts in a particular category, a door leading to another page or site). It is also a goal to make this content work best in VR headsets, but with a workable fallback for browsers.

This plugin includes [Three.js](https://github.com/mrdoob/three.js/), a wonderful creation of [Mr Doob](http://mrdoob.com/) and many others. I am massively impressed by their work. I am also not so great at PHP or Javascript, so please forgive my missteps.

It also has basic WebVR support, where available.

== Development ==

Relies on building the Google "Model Viewer" Web Component

```
git clone git@github.com:GoogleWebComponents/model-viewer.git
cd model-viewer
npm install
npm run build
npm link
```

Then `cd` into this repo and:

```
npm install
npm link @google/model-viewer
npm run build
```

== Installation ==

1. Unzip this plugin in the `/wp-content/plugins/` directory
1. Activate the "glTF Media Type" plugin through the 'Plugins' menu in WordPress
1. Upload .gltf or .glb files via the Media browser, or via the Add Media button for posts/pages.
1. Embed the 3D object in posts using a shortcode, like `[gltf_model scale="1.0" url="http://mywordpresssite.com/wp-content/uploads/2016/12/model.gltf"]. Note: You may get that full URL from the Media browser by selecting the file and copying the link.
1. You may also create a "GLTF Scene" using the "Scene" post type, and attaching a 3D model on the post edit page.
