Compute Sunlight or Shade

Question

I have a 3D building (Google SketchUp, displayed in Google Earth (or Maps)).

Google earth has a feature to "show sunlight across a landscape". How do I show the building's shadow throughout the day? If easier, how can I view the sunlight going into the hitting the sides of the building throughout the day (the angle is most important to me).

Is there a plugin or an add on or entirely different software that could do this for me?

Answer 1

take a look at this.

I think that this support page answers your question in particular look at the time slider for the angle throughout the day
