### Tutorials for Haptics in a dentistry context

Description:

The aim of these tutorials is to understand, step by step, how to create a scene with an Omni phantom device.

This first tutorial shows how to load the visual model of the tooth. The first line defines global parameters for the scene which are attached to the root node of the scene.
Then we build an arborescence to contain the different objects of the scene:

- A root node for all the head
- In the head node, we display the visual model of the head with the OglModelComponent.
- In the head node, we create a new node for the tongue and another for the teeth.
- In each of these nodes, we respectively display the visual model with the OglModelComponent.
