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