ThreeContext
ThreeContext creates a WebGL context using Threejs. It also handle mouse control with two possible logics (orbit or trackball)
An event can be associated to a ThreeContext instance: raycast with the method
.on("raycast", function(hits){...}) where hits is the object list being raycasted.

Get the scene, mainly so that we can externalize things from this file
THREE.Scene:
Get the scene object

Get the png image data as base64, in order to later display it in a markup
Since we are using Controls, applying the lookat just on the camera in not enough
(THREE.Vector3)
a position to look at
Throw a ray from the camera to the pointer, potentially intersect some element.
Can emit the event onRaycast with the section instance as argument
(Object)
the option object
| Name | Description |

Throw the event
'raycast'
with the intersected objects in arguments (default:
false
, the result is returned)

options.parent THREE.Object3D

the raycast will be performed recursively on all the children of this object (default:
this._scene
)
