Another nit picking :
When an object ( say a building ) is culled because it is not in the
view, its shadow is also culled even if it is in the view.
2 screen shots :
In the first, an oracle building cast its shadow on another one
If I go forward a bit, the shadow disappear :
The FOV is exagerated because it is not easy to pause exactly when it
happens, but you can clearly see the shadows poping in and out when you
travel between buildings.
