Is tire deformation very important in racing simulation? What I can see Alpine from the 2nd trailer, just wondering tire deformation will implement in GT6.

tire deformation in the physics model and tire deformation graphically are two different things. You can have one without the other.
 
There is a chance. PD said there was a new tire model, which is vague, does not tell us much. The new model could include a lot of features, all we have to do is wait.
 
I don't see any sign of deformation in that GIF and as Zathra points out graphically showing it and physically modelling it are different.

I can see a tyre clipping into the ground. I don't see any deformation.

Tire derormation would be interesting, but I don't see PD implement that feature, however can be happen, we only need to wait.

Why not, can I ask? Because you've lost faith in them accurately modelling car and tyre physics?

Now there's optimism for you.

So they're only modelling vertical deformation and not horizontal?

If the tyre deformation is physical implemented but not visually modeled, you only will see clipping at tyre compresion and nothing at lateral forces. Exactly what this Alpine animation is showing. In that case there is no way to know for sure what does physically those tyres except if you are PD.

I think it's catching. We could call it the great optimism outbreak of 2013.

Do you guys seriously see a tyre slightly clipping into the road and think "Ooo, tyre deformation must be modelled!" Didn't we go through this with GT5 as well with a couple of videos where it appeared that tyres were clipping into stuff?

Think what you like and I hope you're right, but without further information Occam's Razor cuts that one to ribbons.

There are two possibilities. Either the collision mesh for the road's surface and the tyre are not where their visual counterparts are (which has not been the case to this degree in any GT game), or the intersection is being allowed for some reason.

I already noticed the clipping, but what's more subtle than that is the delay in the rebound of the wheel after it stops moving downwards. That's indicative of an extra spring element - namely, the tyre.

Seriously? Do you seriously think they accurately model the physics? IMO GT's physics are fundamentally flawed even to the point of how they apply acceleration and braking forces.

Your comments and signature border on trolling.

With the performance issues that GT has had on the PS3, I seriously doubt that they would add graphical representation of tire deformation for GT6. The clipping seen could represent tire flex or might just be a glitch. Who knows.

As I said, the absence of graphical deformation in no way insinuates that tire deformation is not in the physics model. iRacing is an example of a game that does have tire deformation in their physics model but doesn't have graphical representation of that deformation.
 
If you watch carefully, just after the rear tyre compresses, it regains it's shape pushing the suspension up some. It wouldn't have that effect unless tyre deformation physics were implemented. I'm with the OP on this one, well spotted sir!

👍
 
I remember the guys at radiolemans also mentioned that they're incorporating sidewall flex as well. Guess we'll see.

I agree that they may have it in the physics engine but not the graphics side of the game.

Are you serious?

Behold, people arguing for a year and a half after release about whether GT5 has tyre deformation.

They may have it in the engine for GT6. As Zero points out, without seeing the code we'll never really know.

But people seeing a visual glitch that's common in racing games (how exactly do you make a non-deforming tyre that always contacts a non-flat surface perfectly?) and assuming that it means there's tyre deformation modelled?

Overwhelming optimism is the nicest way to describe it.
 
I like how the 'evidence' pictures in that thread are pretty much all where real tyre deformation wouldn't/shouldn't occur.

It does look like back the tire cushions the landing before the suspension (rim) starts to move in that gif.

Looks like it but if you don't see the sidewall flexing then there is no actual visual tire deformation. Not a big deal, as long as it is represented within the tire simulation and physics engines it's all gravy from here.

I have to support this post. I have to say that I'm on the fence here, regarding what we're seeing in the topic post's image, unable to rule out the possibility that we could have deformation accounted for in the physics without being represented in the tire graphics. However, being possible doesn't make something probable.

All that we can see is a tire going into the ground. The simplest explanation would be that it's unintended. Believing that it actually represents deformation modeled in the physics engine but not in the graphics engine requires assumptions. From an objective, logical standpoint, we should go with the simpler answer that requires fewer assumptions - that it isn't tire deformation. It might be incorrect, but at this time we have no evidence to it being incorrect.
 
how do they simulate tire pressures without it being merely a extension of suspension rates, therefore redundant?
