I'm afraid, as with the other responses, you think wrong.

The mesh function plots surfaces (functions of TWO variables) in 3-D space with the colormap determining the colour of the surface. I want to plot a function of THREE variables ie. a rectangular lattice of points in 3-space with the colours of the lattice points indicating the value of the function.

This really isn't that complicated a concept, surely there must be someone on the list who understands what I am trying to do even it they don't know how to achieve it ?
