[OpenLayers-Users] Updated Google Maps API and 3D

[Andreas Hocevar]

Hey Steven,

the purpose of adding camera and scene support to OpenLayers 3 is indeed
2.5D views for use cases like tilting and street views. The idea is to tilt
2D tiles and combine them with an elevation model or other height/elevation
information that is associated with the tiles. But we will also be working
on 3D vector rendering, in which case the 3D information is used directly
from the geometries, and all rendering is done on the client.

It seems the use case that you are envisioning is to request tilted tiles
from the server, i.e. to send requests for new tiles whenever the camera
properties change, which will then get rendered on the server and returned
to the client? Is this correct? If so, let's make sure it gets ticketed on
http://github.com/openlayers/ol3, so it won't be forgotten.

Andreas.
