The author develops a spectral defect correction multigrid scheme for three-dimensional elliptic equations. The basic idea is to use a pseudospectral discretization for the defect and a multigrid method based on a finite difference discretization. The multigrid method uses alternating plane relaxation based on Richardson's iteration.
