A Vector3 containing the 3D rotation of the vertices in this Mesh.
The values should be given in radians, i.e. to rotate the vertices by 90
degrees you can use
modelRotation.x = Phaser.Math.DegToRad(90).
Modifying the components of this property will allow you to rotate
the vertices within the Mesh. This happens in the
where each vertex is transformed using the view and projection matrices.
Changing this property will impact all vertices being rendered by this Mesh.
