[Radiance-general] Building on a hillside

[Randolph M. Fritz]

I'm simulating a test structure on a hillside site; the ground drops 
away dramatically.  So a lot of sky is visible below what would be the 
horizon on a level site.  So far as I can tell, the only way to 
simulate this correctly (if the ground reflectance and sky light is 
significant) is to give the model an actual elevation, z = 700 feet or 
whatever.  Do I have that right?
