A Vector3 containing the 3D position of the vertices in this Mesh.
Modifying the components of this property will allow you to reposition where
the vertices are rendered within the Mesh. This happens in the preUpdate
phase,
where each vertex is transformed using the view and projection matrices.
Changing this property will impact all vertices being rendered by this Mesh.
You can also adjust the 'view' by using the pan
methods.
