PGR4: New Snow on the Ring trailer

Further, its not like they immidiately turn into that sort of hubcap once you start moving, they model the induvidual spikes and actual alloy up to a certain speed, then it switches to a more blurry one, and then to a even more blurry one (they all rotate etc).

If this is the case then I take back what I said. I thought you could use the rims as an indication of when a shot was in-game or not, and that the captures of a parked car from such angles could only be photo-mode.

It appears not to be that clear cut, though apparently.

Hubcap-speed-rims are there because its hard to accurately rims going around at a fast enough speed... or something. It either looks to slow, or doesn't look very convincing.

Right now, GT:HD does always show them in full 3d, and like you say, they don't always turn fast enough. Maybe that has changed in GT5:prologue, I'll check the videos again.

I get your point in any case. Which leads me to another quesiton: can you freely move the camera around your car in the game?

@Capeta: yes that was me. Now that I have the game myself, I would just like to modify that to 'severely broken' ;). Like a lot of other things in that game. Other discussion though!
 
Nice choice of picture given the debate above about wheels.

You can clearly see that those wheel centres are 2d with a 3d nipple in the middle.
 
PGR4 2d car wheels are actually more hard to notice in comparasion with GT5 2d car wheels.
Wise choice to use 2d combined with 3d.
 
LBP has excellent rotational motion blur; first time they showed the game it wasn't that good, but from what I can see in the last released videos they improved it.

That's weird, because GT4 already was quite clever in using 2d and 3d combined. Oh well, I guess we'll see how GT5 Prologue turns out soon enough. It seems to be coming along quite well.
 
oh the wheel debate.. let me get up to speed with it..

I can only wonder why after all the pictures you waded through to find that image that had fully modelled wheels you bothered posting it.

Shame you didn't go a bit further down as you would've seen that that car does appear to come with perfectly flat faced alloys.

You could argue that there is no depth to the rims in the action shot (I wouldn't agree as there is a certain amount visible at the bottom of each rim where there is limited blur) but I think all the other shots prove it to be the exception rather than the rule anyway.
 
Wheels

We will have to see more but im sure that GT5 will use 2d wheels combined with 3d aswell.

When I see this video the wheels look 3D because you can see light and shadow from inside part of spokes.

but maybe it is 2D with amazing shader, I dont know.

One mistake I notice is i some GT5P videos is shadows from a-pillar are not always touching a-pillar. I notice this problem in some other games also where you can see someone standing and there will be space between the shadow and the person. Why is this? Will all games have this problem sometimes?

Also, the shadows have jaggies. Also, the dials seem to have little bit lower resolution textures.

Probably because the shadows are baked, what a shame:cry:.
 
light leaking into shadows can be caused by a lot of things: high depth bias, shadows filtered in screen space, variance shadow maps.. or pre-baked shadows..not baked very well :)

Was not GT4 using 2D rims all the time except photomode and car menu?
 
For 2D hub hacks, they ought to apply some parallax mapping to give it depth, indenting the centre. That GT pic looks very poor on the wheels compared to what you'd expect from a GT car.
 
Wheels

Shure looks like 2D without a doubt IMO.

Actually, from the replay shots I saw that car type only has 2d wheels.

See this image of the same car:

This picture of the same car I think they covered wheels in black color so no one sees it.

But other cars always show very beautiful 3D wheels.

Also for gameplay videos it always looks 3D when I pause.

Also, this is the shadow problem. Look at the shadow from the a-pillar section that's at the front bottom corner of the window. Also you can see shadows on driver's glove is jagged. I wonder maybe jagged shadows are real and smooth shadows are baked. Am I crazy?

Interesting, but are the cars really driving fast enough since there is no blurring of the rims as what happens when the wheels spin fast. PGR4 also has 3D rims but when the wheels spin fast they seem to get exchanged for 2D rims. This is what it looks like for GT5 to when the wheels spin fast enough.

Thoose are real-time shadows, it is just that the resolution of the shadowmaps are not high enough to prevent jaggies in certain angles. Also it seems there is some shadow clipping issue. May be due to how they render the shadows (same problems can be seen in BF2 for PC).
