+``<model-viewer>`` is a web component that makes rendering interactive 3D models - optionally in AR - easy to do, on as many browsers and devices as possible. ``<model-viewer>`` strives to give you great defaults for rendering quality and performance.
+
+See `source repository <https://github.com/google/model-viewer>`_ and `documentation <https://modelviewer.dev/>`_.
+
+The model to load is a GLTF 2.0 file format.
+
+See `<https://www.khronos.org/gltf/>`_ and GLTF overview:
+
+.. figure:: https://raw.githubusercontent.com/OCA/web/12.0/web_widget_model_viewer/static/img/gltfOverview.png
+
+Many engine developers have already started transitioning to glTF 2.0 to reap performance, portability and quality benefits, including BabylonJS, three.js, Cesium, Sketchfab, and xeogl and instant3Dhub engines. glTF 2.0 is also seeing industry support by companies such as Adobe, Google, Marmoset, Microsoft, NVIDIA, Oculus, UX3D, and more as well as prominent universities such as, University of Pennsylvania and Sapienza University of Rome.
+
+"example" directory contains the GLB file of a chair, that is rendered in the following way:

+<p><tt class="docutils literal"><span class="pre">&lt;model-viewer&gt;</span></tt> is a web component that makes rendering interactive 3D models - optionally in AR - easy to do, on as many browsers and devices as possible. <tt class="docutils literal"><span class="pre">&lt;model-viewer&gt;</span></tt> strives to give you great defaults for rendering quality and performance.</p>
+<p>See <a class="reference external" href="https://github.com/google/model-viewer">source repository</a> and <a class="reference external" href="https://modelviewer.dev/">documentation</a>.</p>
+<p>The model to load is a GLTF 2.0 file format.</p>
+<p>See <a class="reference external" href="https://www.khronos.org/gltf/">https://www.khronos.org/gltf/</a> and GLTF overview:</p>

+<p>Many engine developers have already started transitioning to glTF 2.0 to reap performance, portability and quality benefits, including BabylonJS, three.js, Cesium, Sketchfab, and xeogl and instant3Dhub engines. glTF 2.0 is also seeing industry support by companies such as Adobe, Google, Marmoset, Microsoft, NVIDIA, Oculus, UX3D, and more as well as prominent universities such as, University of Pennsylvania and Sapienza University of Rome.</p>

+     *
+     * A group of objects that receives a shared animation state.
+     *
+     * Usage:
+     *
+     *  - Add objects you would otherwise pass as 'root' to the
+     *    constructor or the .clipAction method of AnimationMixer.
+     *
+     *  - Instead pass this object as 'root'.
+     *
+     *  - You can also add and remove objects later when the mixer
+     *    is running.
+     *
+     * Note:
+     *
+     *    Objects of this class appear as one object to the mixer,
+     *    so cache control of the individual objects must be done
+     *    on the group.
+     *
+     * Limitation:
+     *
+     *  - The animated properties must be compatible among the
+     *    all objects in the group.
+     *
+     *  - A single property can either be controlled through a
+     *    target group or directly, but not both.

+     *  - Add objects you would otherwise pass as 'root' to the

+     *
+     *  - Instead pass this object as 'root'.
+     *

+     * Note:
+     *
+     *    Objects of this class appear as one object to the mixer,
+     *    so cache control of the individual objects must be done
+     *    on the group.
+     *
+     * Limitation:
+     *
+     *  - The animated properties must be compatible among the
+     *    all objects in the group.
+     *
+     *  - A single property can either be controlled through a
+     *    target group or directly, but not both.

+     * ModelGraft
+     *
+     * This is a coordination primitive between a scene graph as represented by the
+     * output for Three.js' GLTFLoader and a counterpart 3DOM facade. Since this is
+     * the Three.js-specific implementation of the facade, the input is a GLTF-like
+     * object whose keys refer to Three.js-specific constructs (e.g., gltf.scene is
+     * a THREE.Scene).
+     *
+     * When created, the ModelGraft produces a Model that can be traversed and
+     * manipulated to mutate the Three.js scene graph synchronously (but
+     * indirectly). The benefit of this is that mutations to the Three.js scene can
+     * be performed in a Three.js-agnostic fashion that is potentially portable to
+     * alternative rendering backends.
+     *
+     * The scene graph representation produced by the ModelGraft is designed to
+     * match the structures described in the glTF 2.0 spec as closely as possible.
+     * Where there are deviations, it is usually for the purpose of making
+     * synchronization easier, or else for ergonomics. For example, in glTF 2.0, the
+     * graph is a series of flat arrays where nodes cross-reference each other by
+     * index to represent hierarchy, but in a Model nodes have array members
+     * containing refrences to their hierarchical children.
+     *
+     * An important goal of ModelGraft is to enable a scene in one JavaScript
+     * context to be manipulated by script in a remote context, such as a distant
+     * worker thread or even a different process. So, every node in the graph
+     * is able to be serialized, and the serialized form includes an ID that is
+     * locally unique to the ModelGraft instance that the node came from so that
+     * the remote context can refer back to it. A ModelGraft can be thought of as
+     * the host execution context counterpart to the ModelKernel in the scene graph
