Hi Leah, > Everytime I've mentioned using a VisADLineArray, I've been encouraged to > use a Gridded2DSet. Could someone please outline for me the pros and cons > of using VisADLineArrays and Gridded2DSets? Why do Gridded2DSets seem to > be preferred? Because the numbers you put into a Gridded2DSet are RealType values (e.g., pressure, latitude) with Units, CoordinateSystems, etc. When you display them, ScalarMaps scaling, Unit conversions, coordinate transforms, etc are done implicitly as needed. The numbers you put into a VisADLineArray for Shape are in XYZ graphics coordinates, so you must explicitly manage ScalarMap scalaing, etc. > Also, is there an example of how to use a VisADLineStripArray? I've > searched for one, but haven't found any yet. There are examples of VisADLineArray in the Test27, Test46 and Test47 programs in visad/examples. There is no example using VisADLineStripArray, but its just a more space-efficient variation on VisADLineArray. Cheers, Bill
