Hi,

I found that one of your examples, Terrain 3D + 3D Buildings, is actually
requesting "GetScene" only, while the example for Terrain 3D is requesting
"GetTile".

As far as I understand that GetTile is for terrain and GetScene is for 3D
buildings, right?

Regarding this, I looked at your running geoserver and found that there are
two different layers used for Terrain 3D, dem_tiled_3d and dem_3d. While
dem_tiled_3d has tiles' information as well as geometry type, dem_3d has
geometry type only.

The reason that dem_3d is not tiled is because you cannot request GetTile
and GetScene simultaneously?
Is it correct that W3DS spec. document suggests it?

Also, would you explain what geometry type is expected in the wkb_geometry
field of the PostGIS tables (i.e., dem_3d and dem_tiled_3d) for use as a
data source for a terrain model for the GeoServer W3DS?


Thank you!
Kim.
