Mappings for 3D Landscape

A rather dumb question here. I'm relatively new to graphics/visualization,
so please bear with me a bit.

With a simple MathType such as (RealType.Time -> (value1, value2, ...
valueN)), is it possible to create a simple 3D landscape? If its possible,
what kind of mappings would it be like?

If it's not possible, what kind of data model would be most suitable?

Thanks a lot in advance!


p/s Bill, thanks a lot for your help to my other question. It's working
quite ok. Thanks, and enjoy your trip!
