3D rendering offline

Question asked by Crittermap on Jun 7, 2017

Is it a practical scenario to display a 3D Scene offline?

 

This example shows it online:

Display a scene—ArcGIS Runtime SDK for .NET | ArcGIS for Developers 

 

It is using an ArcGISTiledElevationLayer as the source for the surface layer. 

There is no constructor that takes a tilecache or anything else offline. 

 

There does not appear to be a way that I can subclass ElevationSource and come up with the right methods to override. 

 

RasterElevationSource can take a list of raster files, but does not note what kind of elevation raster file formats are acceptable. Perhaps that is obvious to those here who are more experienced. What kind are they and where do you get them? 

 

How big would such raster files be per size of area, for example per degree of Long/Latitude?

I'm assuming that having a list of thousands or so would not be good for performance, so I guess you would also have to narrow them down to the files that are applicable to the current area.
