PHYSICS Introducing the 5 point tyre model for ACC!

<3 u KS

 

"Tire performance" = lap time, if you want
"More than 5 points" = computational performance, it's about a very complex problem https://en.wikipedia.org/wiki/Collision_detection
But in any way, excellent wordplay !

 

I believe the only other game that has used a grid was pcars 2, however no details of how many points were used, only that it was a "Finite Element Grid". It's probably safe to say they used 3 or more points since 3 points make a plane, I can say it's safe to say Kunos has done their homework on the matter so Im positive the implementation will be much better!

 

To all DEVS...

 

I was under the impression they all used more than one point. I was surprised when Kunos said AC and ACC were single point.

 

Thanks Aris, very interesting write.

Indeed the curbs were one point in AC (and ACC as well) that always bothered me. Especially at Nordschleife where you can see race drivers taking every second curb (in dry weather) while in AC it was always best to stay away from most of them unless you have quick reflexes.
So I'm very curious to see how the new tyre model feels.
Just a bit sad that I can't take it out on Nordschleife for a comparison to the old behavior.

One other thing that always bugged me in AC was that when the tyre contact point moved from the tarmac to the curb you could often feel a huge spike in the FFB forces (which on DD wheels can be very harsh).
So this was also caused by the simplifications that were made with the single contact point?
And with the multipoint approach it would be gone (or at least not pronounced anymore)?

tbh, even if not: we're now at a point where 8 very capable cores is almost standard for new systems and we are nearing 16 cores and 32 threads for consumer desktops.
So there is CPU performance to spend and it would be well invested.

 

/me cries in i5 6series.

 

hmm, so that's how it went down at the Kunos HQ?

Aris: we should achieve identical performance with the new tyre model
Stefano: well, this would be physically impossible
Fernando: hold my beer …

 

Your i5 beats my FX4350 easily.

 

Your monitor to my Rift: Hold my beer.

Enough with the off topic though

 

New monitor (5720×1440) already ordered. My CPU/GPU are crying.

(new CPU will follow soon thankfully)

 

Great stuff! Thanks for taking your time to write this and add screenshots. Can't wait to try it out.

 

Complete sim racing nerdgasm to read through this one @Aristotelis - can't wait to try this out in practice (well... in a virtual manner of speaking anyway ). Keep up the good work guys!

 

I'm very much impressed. I was eagerly anticipating the "improvements" you announced on this topic...but this is not an improvement, it's a new game! Love your work - Kunos = Quality. <3

 

Over hyped. Now let’s just wait

 

Will this model add to the output signal to give more Kerb effect to SimVibe and other programs?

 

Since the tyre grip will like be some sort of average between those 5 points, I'm guessing the same average will be sent to those external programs.

 

Thank you, looking forward to this one!

 

It's this attention to detail that is why I'll pretty much buy just about anything that Kunos touches. Well done.

 

Can't wait to try it out!
