Actually, I don't think it's necessarily all that complicated. It depends on the data scheme, but as long as you assume that the sim is holding the "master copy" of things there's no problem. For each data cycle, OpenGC reads the state of the sim, displays the relevant stuff, and then writes whatever changes the user requests back to the sim (which I suppose would have the option of rejecting the input). > One advantage of using OpenGC is to reduce the CPU and GPU workload on > the > FG side.

Perhaps in regards to the cockpit displays, but I don't think the nav stuff requires all that much CPU. > Again, I've not kept pace with the lastest CVS, there may be some > legacy > code (circa 2001) that might still work with fgfs...

The old flightgear interface didn't work on Windows, whereas the new one does. I think the main issue now is exporting the nav needle positions correctly, which I don't think should be _that_ big of a deal.

Once he whittled me a toy boat out of a larger toy boat I had. It was almost as good as the first one, except now it had bumpy whittle marks all over it. And no paint, because he had whittled off the paint. |
