I'm a game developer and owner of Reflective Layer, an independent game studio in Philadelphia. We started out as indie film maker but then in 2007 switched to indie games. Our current project is Prague. It's a RTS/ village building game featuring a computer simulated weather system which generates wind, rain, snow and other metrological conditions. These conditions impact gameplay in every aspect.
now thats what im talkin about!
None of the above :-)
The land is modeled flat(in 2D)
The engine only model changes in density of the the air which results in updraft and wind.
Temperature drops with altitude.
Albedo is also modeled in the engine. It really comes into effect with snow. Although the Lightning Weather Engine can model snow, there won't be any snow in Prague because the complication it would cause with the story line.
Are you including levels of air for fun effects like inversions?
Is the ground all flat or is it bumpy enough for fun effects like downslope warming?
Do the bodies of water buffer the temperature extremes like they do in real life?
