smoothing functions to avoid artifacts in graphs

I'm trying to make a 3D plot of a rapidly varying positive function, 
but no matter by how much I increase PlotPoints, I get artifacts, 
probably due to  insufficient sampling. When I change the PotPoints 
number, the artifacts change cahracter but remain present. Old plots I 
have with another system of the same function are smooth and reflect its true 
behavior. Does Mathematica have an option to smooth data before 
plotting?

Thanks,
