Using De Casteljau's algorithm to calculate a point upon a Bezier curve where u == 0.5
The following diagram shows the control points used to generate our cubic Bezier surface:

There's more…
At this point, we have only scratched the surface of what can be done with tessellation.
With the exception of the Bezier patch, our tessellation has only created additional triangles,
and they have not been displaced or otherwise manipulated to improve the level of detail.
For example, if we were to apply the triangle tessellation against a 3D mesh, we would see
that the mesh remains in the same shape albeit with a denser distribution of triangles.
