Ok, thanks. I've thinked a bit more about this whole idea and, since i was planning to code Motorsport as a library instead of as a standalon executable, maybe Motorsport can be used from FlightGear, instead of being coded inside it. It looks like FG already uses several different physics engines

I'm unable to find the Jeep or any other car that were mentioned.. haven't searched much though. Quick question: by "ground reactions" you mean collision detection and response? Are there no plane-to-plane collisions currently, only basic plane-to-ground? And is the ground a generic trimesh or a h

Just to help you. X-plane simulates springs and tires and has an open interface. People have built cars for x-plane. The roads suck though. I think it would be great if fgear did this too. On Fri, 30 Nov 2007 5:39 pm, STenyaK (Bruno Gonzalez) wrote: > I'm not familiar with the suspension geometr

I think it's worth pointing out that in FlightGear cvs we have models of a jeep and of a snowplow (truck). The dynamics are based on YAsim and the wheel/suspension modeling seems to work really well. I was actually very impressed at the sorts of things that YAsim does ... Andy coo

I'm not familiar with the suspension geometry of planes, but i *guess* it can be modelled as a series of "bodies", "joints", "springs" and "dampers", together with the tire model. Planes tires are pretty big, so they're an important part of the suspension process in landings too (and braking.. pla
