I allways dreamed of a flightsimulator with good ground detail where you can start from earth and fly into space seamlessly with a rocket. :) One year ago i found a great simulator for planets that heavly used LOD algorithms. In that simulator you were able to move from high detailed ground up into an orbit around the planet which used lower quailtity ground detail. The sad thing is, i can't remember the name of that programme. :( The only thing i can remember is, that it was an open source simulator that worked under linux and used the planet mars as an example. Those LOD algorithms could be very valuable for flightgear if we would use them for fg. I allready searched for that simulator yesterday via google, but i didn't found it. That's quite difficult without knowing the name of it. Does anyone know the name of that simulator?
