3D Surface Controls

Isosurfaces can be made in two types of displays, regular isosurfaces, and isosurfaces colored by another parameter. An isosurface is a 3D surface mapping the location of a single parameter value through a 3D field. Isosurfaces are a 3D analog of a single contour line in a 2D plot; the intersection of an isosurface and any plane is a contour line of the same value in that plane.

Coloring an isosurface by another parameter can serve many purposes. One example use of this is creating a display for possible icing conditions in the atmosphere that could be useful for pilots. To do this, you would select Temperature as your field, the "Isosurface colored by another parameter" display type, and Relative Humidity in the Field Selector window that appears when you click Create Display. After the display is created, you can set the isosurface value for Temperature to be 0 degrees Celsius in the Layer Controls tab of the Data Explorer. Now, in the Main Display window, you have a surface of 0 degrees Celsius colored by Relative Humidity. Wherever you see high RH values means that there is a lot of moisture in the atmosphere, and at the freezing temperatures, there could be icing conditions.
