Hi. I'm looking for any links/sources of info where I can learn more about the technology behind GT3.

I'm an aspiring game programmer, and any technical insight into the software engine, API's, development tools that were used, etc. would be greatly appreciated. Thanks!
 
I think gamespot had announced that 500 PS2 SDK's had been made avaliable to the general public a while back. I'd type "PS2 SDK" into a couple search engines.

Thanks. I've thought about that. I guess what I'm really interested in is the design and implementation of the actual code. I've read in one interview where the game is locked at 60fps, which gives me some insight into the game loop they used.

Another thing i'd love to know more about is how they implemented the replay sequences. Do they use input and time to create the replay on the fly, or do they record and recreate sequences through interpolation of full state data for a limited number of selected frames?
 
I think its definitely thru an input log. You can recreate the full race if you have the input logs for every car in the race.

Otherwise, if they use any other technique, I don't think they will have enough memory to replay a 200 lap endurance race
 
Yes, I'd say it's most definitely through an input log. Ever notice all the stats recorded in the "Analyze" section that you can view after a race? It wouldn't suprise me if the replays were created real-time with that same data.

Mayb someone should ask Polyphony ? **hint**;)
 
I'm also pretty sure it's input based. On the PS1 GT games, the replay saves were ~twice the size if you used the analog instead of the d-pad. Good luck with your search, EP! :)
