3D

In fact, this Google Earth program is built into Google Maps.
In order to take advantage of this effect, you need to go into the photo mode and the 3D button below the compass will appear.

The terrain is very well implemented: mountains, valleys ...
As for the cities they remained flat, although the whole picture is tilted. The real effect of 3D up to the trees is only in the large cities of the Western world (Europe, Australia, Canada) and much of the US.

To hold the circle, hold down the Ctrl or Shift and use the mouse.
