%X n this paper we demonstrate that the Monte Carlo simulation package McStas is a useful tool, not only for instrument design, but also for resolution function calculation. It has been possible to determine analytically the four-dimensional resolution function of both a direct geometry time of flight neutron spectrometer and a triple axis spectrometer. The obtained resolution functions are directly comparable to and in agreement with the Monte Carlo simulated results. These results are a step towards incorporating a four-dimensional resolution function into data analysis. For each instrument we show an example of the resolution function calculated at a particluar point in (Q, ω) space.
