We give the definition of D-invariant points on an irreducible algebraic hypersurface V in R N. We show that every regular point on irreducible quadratic hypersurface in R N is D-invariant. We prove that the local Taylor interpolation projector at a regular point a ∈ V is an ideal projector if and only if a is D-invariant
