Hello,

I came across an interesting interview about tyre physics which may help you to understand the difficulties and challenges developers face when writing their simulator. If you watched the whole video you might become more patient in relation to LFS development

Personally, it gave me an insight on the size of the challenge Scawen is currently facing. Beware, this video can be rather technical so it might not be your cup of tea if you are not interested in knowing more about tyre physics. This interview made me rather curious, I wonder which road Scawen choose or how LFS tyre physics relate to what is discussed during the interview. Hopefully, some of you are "knowledge hungry" and will enjoy this video. The interview ends with an optimistic conclusion. Thanks to the evolution of hardware developers now have more room for improvements. Some may also understand why it takes Scawen time to develop tyre physics, it is by all means not an easy challenge ;-)

thought i would just take a look and ended up watching it all Hope scawen wont give up on tyres and really liked the new ideas with simpler physics.
edit: also as i understand scawen tried to do the model with formulas but now hes doing the table one right?

Same for me, I watched the whole thing Amazing stuff indeed.

And he actually misspelt "pacejka" model as "pajechka"

Well, it's old (posting date 2007 gives away as much). He mostly talks about Pacejka, which as I understand is a formula pretty much every sim worth its money (and the term simulation) is moving away from... Consensus from the developers seems that Pacejka just goes haywire when the speed goes to zero and messes up the slip angles after peak in some way... This is of no importance to tyre manufacturers who just want a nice normalized graph to show how good their tyre is, but for us who spend many a time over peak and subsequently at standstill it's less than ideal...

hmmm.... i have the strong feeling that Skawn woold more as he could handle, and he have now fear to say again that he must start from new like 3 Jears agoe, and now we can watch dieing LFS more and more (specialy after the releas of race factor2).

And after reading the last post from Skawn,that says to me Eat what I cook or die.Thats not friendly, for me it´s a arrogance that he can not afford after 3 Years waiting time and nothing more as we are working at the tires!

But I couldn´t understand why he didn´t give us new Trackas cars may be rain with the old tire physiks and give us the new physik as a patch like at the Y and Z patch.
So they can make money with the new licence and we have somthing to do.

Sorry my bad english

I agree with you. Small Progress such as tracks/cars is better than no progress at all.

Outdated as it might be, it is still interesting to watch. I wanted to just click it through as I do with porn but I actually ended up watching the whole damn thing.

As for you guys starting the never-ending development discussion again, I say that Scawen is not just developing tyre physics. He is developing a platform, because on those tyre physics (which will be more versatile than now), he can build new suspension types, maybe flexible body physics, weather conditions etc. Now, you'd have to program a new type of simulation for wet track. With the new tyre physics, he'd just set amount_of_water_on_track_polygon = 1.2l and off you go aquaplanning. But don't quote me on that
You need the best possible platform to build success on it.

That's what we hope for

Kind of - he's built/building a test rig that is very detailed (formulas) but too slow to put into LFS (a couple of seconds per frame!), and is using that to test various ways of approximating those answers quickly enough to use in LFS. Not sure if those quicker ways are just simplifications, or table lookups, or even just magic, but if they pass comparison to the test rig, it's all good.

There is your problem.

Interesting video, annoying interviewericist.

Yeah, as far as I've gathered from his posts, he's using his own detailed formulas and a non-real-time test rig to generate look up tables for the sim to use real-time.

this game is long gone before any update is released. it kind of is already.

Sad but true

Ok then he would build a new platform it´s much better for more developement.And I respect Scawn for giving good working Patches.

And I would give him the time he need for the new platform!

But why could he give us not a bit mor as the last patches,not the full new game but more as some new track conficts I would pay for it.

But at moment look at the LFS Server list and you see only 1 racing sever ( CG ) and the rest is drifting and crusing I could remember other times.
I have spend many houres in ths game and it makes me sad to see what happen to this great community and game.

Thats why I say something like this first and last time,pleas don´t miss understand me it´s nothing against Scawn and hes worke on new stuff for more realistic fun.Í scream a bit for help to save the last racers to build a new "old" big community.
