Given a function of two variables f(x,y), uniformly sampled in x and y, what is the easiest and most efficient way of plotting the surface f with grid lines running in the x and y directions? To achieve effective hidden line removal, it seems that interpolation is necessary since the sampling density is likely to be less than the plotter resolution. Also, the number of samples in each direction and the viewing angle should be variables in the algorithm. References to books or articles detailing a good algorithm are appreciated. I subscribe to ACM SIGGRAPH AND IEEE CGS, and the articles I've seen are at a much more complex level than what I'm looking for.
