Splitting an existing triangle into sub-triangles would not create
any smoothing.  In the absence of occluding objects, the rendered
image of the new set of smaller triangles is indistiguishable from that
of the original single triangle.

The issue of interpolation only arises if you need to  assign a color to
the newly created vertex based on differing colors belonging to the
existing vertices.
