(nice to read an ng where the topic gets discussed) I read on a web site somewhere an interview with one of the programming team working on Nascar 3. He (programmer) said that he could tap his road car details into the physics engine and reproduce driving to the shops (or something along those lines). If this is so easy, can we then have........ 1 - A sim of '50s F1. Namely the front engined cars. 2 - A Touring car sim. I read somewhere that the BTCC alone gets 1 billion viewers a season so there's bound to be demand for it, even if not in North America. 3 - A modern F1 sim taking the same approach as that with GPL. ie reproducing F3000 cars and F3 cars in the same simulation. Oh, and driving aids such as those incorporated in GP2 would be a must to get it on the mass-market. I'm aware that circuits and scenery have to been drawn/programmed for each one so this obviously elongates the time taken to produce the thing drastically. But surely if the physics engine is as good as they claim and the only reason for Papy's existence is to produce top-notch racing sims then they would do it. Most game companies would kill to have this amount of material to work on for their next releases.
Should (are?) Papyrus consider licensing their game engine like Id have? This could open up a wealth of racing titles from companies very capable of producing the graphics, setting the appropriate levels for the physics of the cars in question. These could form the basis of bolt ons to GPL, using the cars & tracks as they are developed by the third parties.

Agreed. We would end up with a ton of sims saying on the box "Uses Papyrus' Physics Engine" and the rest of the thing could very easily be poor. Perhaps it could be done in a way where Papy could require that any title using it's engine pass their quality standards, however. It would be great to see just about every popular form of motorsport covered by something like this. As long as it's done well. Could be a way of the future in fact.
Byron, the downside of any sale of technology is that it takes away the competitiveness. If Papyrus sold their "engine" then the incentive for others to better that technology is diminished. Under the licensing agreement the buyer would not be able to develop any new technology from that which they bought under license.

Hi, Just for the record, Papyrus isn't the only one with a good vehicle dynamics model (aka "physics model") -- for example, Atari still has the model that was used in Hard Drivin' and it's pretty easy to change the input parameters to make it handle like any car. The same people that did HD wrote a new model that is used in the Silicon Motor Speedway (www.lbet.com). Also, we have a number of analysis models that we sell (to car/tire manufacturers) that probably wouldn't be all that hard to make run in realtime -- and they have actually been validated against instrumented tests on real cars... I don't think that you have to worry about competition! Sincerely, -- Doug Milliken Research Associates Inc.

I don't think anyone has really claimed that Papy's "only reason for existence [sic]" is to produce top-notch racing sims. Profitability (and indeed, risk-weighted profitability) is a very important concern to keep the lights on and the programmers fed. ---Jim
