Look at the viewimage-application (under the GIS/surface menu)
You can display xyz datasets and drape a colour image over the elevation
grid. So f(x,y) and g(x,y) could be coded as height and colour respectively.
Viewimage even lets you interactively change the viewing parameters.

This is not supported within khoros 1.0.
