Re: Program to visualize layers

Hi Ugo,
 
Excellent work on your DEMViewer.
 
One appraoch to multiple layers would be to make each layer
a different data object, each with a Linear2DSet domain set.
Each data object (i.e., each layer) would be connected to the
DisplayImplJ3D by its own addReference call which would
include a ConstantMap[] array to set each layer at a different
ZAxis value, and possibly an Alpha value for transparency.
You could disable a layer by calling setData(null) on its
DataReference, and enable it by calling setData(layer_data)
where layer_data is just the data object for the layer.
 
Good luck, and let us know if you have any problems or
questions.
 
Cheers,
Bill
