You probably know TFP can render sunlight for specific long/lat locations for various times of month/day/hour.
And it you want to make a video, you can render a set of images and combine them into a video playback.
But if you want a 3D display of the sun's path, you can use a free plug-in in SketchUp (works in the free version 7) that will render an image and of course you can import an .skp file and use it in TFP.
I don't remember the plug-in name/source off-hand, but if anyone is interested you could Google it....or reply here and I'll find an example and the plug-in name....its on my desktop PC in my office.
