Euro Gamer report on PD Backstage at E3

[analog]

this is only a quote that I found on an italian forum.. can't find the real source!!

"Premium cars have been designed in absolutely painstaking detail: In addition to the standard damage modelling and exterior deterioration, these cars have been built so that they can come apart panel by panel. Their interiors can be navigated. Due to the inclusion of rolling physics, the undersides of all premium cars have also been lovingly replicated. It’s here that Kazunori insists that he’s found the PS3’s limitations."

Thanks Loeb80, it explains this whole issue in a new more nuanced way compared with the reports I've seen thusfar.👍

GT5P... yes. So it's from scratch, still.

Sorry I MEANT GTpsp sorry so yhea I guess If you consider making the cars for a handheld game and then porting it to GT5 as "making them from scratch"

And I quote

there's over 800 of them, they cover the majority of the vehicles included in all the previous Gran Turismo games, including the PSP version, and they've been optimised and upscaled for the PS3.

That's not how you do it. You don't build models for PSP then upscale. You do them for the biggest platform (PS3) then downscale and use a low poly version for GT-PSP. Upscaling would be the same as remaking them from scratch as in the other way around, isn't.

Upscaling by definition is basically changing something that is one size or resolution to another.

So that to me sounds like they have taken the gtpsp cars and made them higher resolution... and also made some minor optimization changes. That is how that reads to me.

Info is from the GameSpot GT5 writeup from the closed door session

Actually the models are the data from GT4's assets, basically the information they accumulated when they scanned and photographed vehicles from GT4. The data was high resolution to begin with, so they could scale down easily to what the PS2 could handle. With GT5 they just used the high resolution detail and added more detail to help the vehicles be visually on par with the purposely built GT5 models.

Ah was relieved to hear all cars have interiors, just premium ones like i said have damage modeling, but also the standard interiors are basically standard interior for whatever car that is. No extra detail was added, and definitely no deformation of any kind. I am resting happily tonight. Forgot to place my pre order for the CE of the game. I must be losing my marbles.

I don't mean to sound disrespectful, but your claim is a direct contradiction to Kazunori's "scratch" quotes.

Having said that though, a photo of a 1969 Corvette is not going to change ever. The dimensions of an 18" wheel remain the same regardless of what you turn it into.

I am quite certain that no game data from GT4 was ported over to GT5. The source material used though in both games may be the same and by that I mean measurements and photography, colour samples and the like.

But in terms of "building" on a GT4 "model", then I think you're well off the mark.

They are not building on the GT4 models. They are building on the models they made for GT4, which where more detailed than the ones that actually were in GT4. (It's 'easy' to lessen the polycount).

At least that is what he was trying to say, not sure whether it's true

You really can follow the action as closely as you want, too, moving about the track, focusing in on the separate cars, and sending messages to the players who are racing, hopefully catching them at just the wrong moment so they make a mess of the next corner and dump their Porsche into a nearby tree.
