Meshing a surface in space into triangles

I have a triangulation in space (nv x 3 matrix of x y z vetex coord. and a nf x 3 matrix of connectivity data, see figure).

Now I want to mesh that surface into triangular finite elements of quadratic geometric order e.g. 6 nodes per element using

model = createpde(1)

**************************

...construct geometry??????

**************************

mesh=generateMesh(model,'GeometricOrder','quadratic')

My question: How do I proceed to construct the geometry of the model

Thank you very much, Ansgar.
