For example if you just want to get a vector with positions over the surface You have just to write

TrivialSampler<MyMesh> ts(myVec);
SurfaceSampling<MyMesh, TrivialSampler<MyMesh> >::Montecarlo(M, ts, SampleNum);
SurfaceSampling<MyMesh, TrivialSampler<MyMesh> >::Montecarlo(M, TrivialSampler<MyMesh>(myVec), SampleNum);
