Hi Ethan, > 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? A terrain visualization is usually created from data with the MathType: ((x, y) -> elevation) where there is some expectation that elevation will be a continuous function of x and y. In the case of your time series data, there may be an expectation that value1, ..., valueN will be continuous functions of Time, in which case you can plot them as graphs (sort of the 1-D analog of terrains) by mapping Time -> XAxis and valueI -> YAxis. If you add a mapping valueJ -> ZAxis, you'll get a line winding through 3-D. > If it's not possible, what kind of data model would be most suitable? People do sometimes generate terrains from financial data, when one variable is a function of two others. For example, the price of an option may be a function of both share price and interest rate. As a MathType this would be: ((share_price, interest_rate) -> option_price) which would make a nice terrain display with the ScalarMaps: share_price -> XAxis interest_rate -> YAxis option_price -> ZAxis Good luck, Bill ---------------------------------------------------------- Bill Hibbard, SSEC, 1225 W.
