I already have a pretty complete car model with suspension, engine, transmission, tires and all that good stuff. I was hoping to figure out how to make this model run in FlightGear-land. My biggest questions are: 1) How do I add a model to FlightGear? Do I need to derive from a specific class? How do I register the vehicle with the program? What sort of initialization do I have to do? 2) How do I interact with the environment? How are collisions detected and how are vehicles notified? How is information about surfaces (grass, concrete, etc.) passed? If anyone has info, docs, or examples that might help me out, please let me know. Thanks.
