(mathematics) interpolation on a surface of more than two dimensions.
The resulting "filtered polynomial approximation" (a spherical polynomial of degree 2L-1) is then made fully discrete by approximating the inner product integrals by an N-point cubature rule of suitably high polynomial degree of precision, giving an approximation called "filtered hyperinterpolation".
Use hyperinterpolation when its meaning, tone and grammar fit the full sentence. A synonym is not always a direct replacement.
