Those pics of the ZR1... is that tire deformation?

Forza has had it since FM3.

I can see where this is going...

Hardly. I was merely correcting the untrue statement made about tire deformation in other Sims. Having watched the video in question, I see no tire deformation.
On topic enough for you? Cause your post certainly wasn't ;)
 
Well, my imagination anyway. But there is something i want to poin it out...
In GT5 you can archieve realistic lap times right?
So... in theroy maybe they have a tire model advance enough to make it possible BUT is not "visible"... Ps3 is somewhat limited on resources...
just a guess...
 
On second thought, tyre deformation would only be good for photomode I reckon. You could use it to justify the use fo camber, but we already know that it makes a difference to the car handling in GT5.

I dont see how else it would add to the realistic experience of car handling other than taking cool photos of cars cornering hard with it showing in the tyres.
 
So, you don't see how making the game more realistic by modeling *accurate* tire physics (instead of the questionable calculations that they use now) would change the way it drives?
:lol:
 
I thought I was the only one seeing it. I'm glad I'm not. I doubt it'll make it into future updates though. I expect the video is more than just a reply from in game footage.

So there is now two who see it...
on second 25-28?? right on the chicane...
 
To have tire deformation, PD would need a overhaul of the physics engine. Considering how crappy the tire model currently is, they would have a LOT of work to do to even consider bringing tire deformation. But here's hoping it will happen :D

rfactor 2 also has tyre deformation

True but it's not out yet, and other games like C.A.R.S are suppose to have it as well. However, these aren't out yet so that is somewhat not proven yet.

Man if they did bring in tire deformation along with alot of other stuff like varying tire models and rubber build up, we'd have a great game. A game that would be worth trying to be number one at.
 
I think GT5 has it.... Well of course how the hell are your tires loosing grip from being exposed to alot of lateral forces. I say it has it, but it doesnt show it visually, but yet again it doesnt show a vast array deformation variables. No they dont need to redo their physics model, just add to it. No game will have realistic lap times... Wana see someone go over a whole track with a profilometer and implement it into a game.

Have you played other racing sims with actual tire deformation? Just curious.
 
With the lack of tire skip and scrub, it's fairly easy to conclude tire deformation isn't part of the current game engine.

One need only go as far as the more arcade-ish (but extremely well-detailed) physics of Need for Speed Shift to see an example of how Gran Turismo could model tires better.

Well I see Niky came in for the K.O. before I could set up shop

Yeah, but much improved in 4.

I doubt a new tire model would make it into GT5 this late in the game.

Forza's is more for looks than anything else tho. With less air in the tire the side wall acts the same when looking at it in game. Compared to LFS were it actually shows a difference making the tire look flat.👍

LFS should be the standard for tire modelling in games visually in my opinion. The deformation looks good, and wheels spin really good. I agree GT5's tire modelling lacks some realism. Maybe Kaz could implement some real world tires as that would make it far easier.

Without wanting to turn this into a FM vs GT thread I would have to disagree with that, the deformation most certainly is not mainly for looks, but has quite a profound effect on the handling.

Info and discussion would be in this thread however...

...with a nice video and picture of tyre deformation, which I believe does also nicely show how it affects the physics as well.

Note - As I say this does push this thread off topic - so please continue any discussion about Foza tyre deformation and how it compares to GT is the linked thread. Ta :)

This is what I mean, not graphically shown but it is aplied in the Physics, or just part of it.
Tire Pressure is something missing, maybe this data is just the tire pressure that the manufacturers use? 30-32 psi?

But the physics in GT5 are very well detailed, not perfect but still one of the best out there.

Other point that I'm curious, physics before and after Spec II... could someone make a change log?
It would be nice to determine the "variables" that changed.




And please, stay on topic:tup:

Lol at telling an SMod to stay on topic,

On topic, no, I don't see any tire deformation in the NSX video. Wish there was though.

Well i was refering to everyone else, no to the Moderator. :crazy:
sorry, my mistake

I quote you for the other thread.👍
 
If you check better, it's the result of poor or inaccurate collision detection with the road, although that might be a deliberate choice to simulate (albeit only visually) some sort of deformation of tires under load.
 
Or clipping tire.

On the other hand I've often mulled around the idea, that maybe the tires clip the surface under load on purpose and from that they could calculate on the fly roughly the added / reduced contact patch.. kind of low tech tire deformation? :p





edit, tree'd
