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

[Stephen Woodbridge]

Hi Andreas,

I created a ticket:
    https://github.com/openlayers/ol3/issues/89
please feel free to add to it as appropriate.

I can think of a couple of use cases that this might come in handy for:

1. one is the obvious one of something like Street View
2. another is being able to do a walk through or fly through the 
environment. This could be done via user controls like look right, left, 
up, down and move forward, backwards, right left. Or it could be done by 
creating a path or route through the scene and then flying the camera 
along the path. This might be a sequence of points in space where each 
point has attributes for the camera, like azimuth, elevation, camera 
angle, etc.

Thanks,
   -Steve
