I originally found this at Reddit’s r/forza, though it has also been posted on the forzamotorsport.net forums recently as well. In either case, Brian Beckman, the physicist behind Forza’s tire model, gives an incredible hour-long presentation on the complications of the physics system behind the tires. Note that this is from 2007 which would be about the time of Forza 2. He includes quite a bit of math, and some interesting analogies to flight simulators as well. There’s also a great blend between the real-world physics models of a tire, and how that gets condensed into something an xbox can chew on. While there’s not any direct tie-in to sound, when you combine some of the parameters he discusses with the tire-based concepts Nick talked about yesterday, it’s amazing to see just how complex and integreated the entire system is.
You can also view the entire presentation as a PDF or word document.
I’d be really interested to hear what Brian has to say with the new Pirelli-Turn 10 partnership over Forza 4, and if any major changes have come by.
