Hi,
Thank you for the response! I have an additional question. >No the reason is quite simplistic, a need to show that W3DS can serve a huge model so >i use the terrain as huge model. If you can request GetTile and GetScene simultaneously, >is client issue. What do you mean by "client issue"? What would be the requested URL if I want to request both "GetTile and GetScene" simultaneously? I tried to send both requests with some combinations, but none of them worked. I hope you let me know some example of requested urls. Happy New Year~ Kim.

As far as I understand that GetTile is for terrain and GetScene is for 3D buildings, right? Well is not so black and white. The choice between GetTile or GetScene operation lies on efficiency. The main use case for GetTile operation is to query terrains, but can be also used for query any kind of tiled layer. GetScene operation can retrieve a whole scene, the scene can contain a terrain or anything else. Basically, the specification don't limit the content kind of the layer you can retrieve with GetScene or with GetTile operation, she only put some restrictions on the layers properties, for example, a layer to be served by GetTile operation need to be tiled. 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 layer dem_3d is the 3D mesh produced, so he can be seen as huge 3D model, dem_tiled_3d is exactly the same terrain but partioned on tiles to be serve by GetTile operation. He also have diferent LODs. 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? No the reason is quite simplistic, a need to show that W3DS can serve a huge model so i use the terrain as huge model. If you can request GetTile and GetScene simultaneously, is client issue. 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? The kind of geometry is irrelevant, for this terrains i used MULTIPOLYGON but the new version of postgis support TIN and i think is better choice, but i don't know if Geoserver can handle it. Thank you! Kim.
