Could Doom3 be pulled of on the Gamecube?

Normal mapping and bump mapping are not the same thing.

Some good reading in here, thanks guys, I knew It could be done, but to what extent was my issue.
AndI dont trust a word out of Carmack's mouth, he's an arrogant nerd, nothing more.

No. None of the consoles can handle it. Just because Xbox has a butchered version doesn't mean it's handling it.
The PC version is extremely heavy on lighting. Beyond this generation of consoles. That and it has well defined textures and massive amounts of bump mapping.
So could Gamecube handle a butchered version? Certainly. It would be weaker than Xbox on some accounts, and better in others. Xbox would have more true sound tho, so Xbox wins.

DOT3 BM is indeed the same as normal mapping.

Carmack is the man, don't diss the guy.
The Xbox was around the hardware design that Carmack was shooting for, that's why he had all the nice things to say about it. GC Doom 3 < Xbox Doom 3 < High End PC Doom 3
Obviously that's all just speculation, but it's an educated guess.

Thats not true, the Majority of PC FPS players I know, including myself thought Doom3 was nothing more than a tech demo. We all got it for the hype and got bored of it after a few hours. I'm sorry but people won't love it just because it's an FPS.

I think you missed the point..
Short answer:
No, not the way Carmack intended his lighting algorithm to run.
Longer answer:
The Gamecube GPU simply does not have the featureset that Carmack needs to run the Doom3 lighting algorithm as it is intended to be run.
Of the current generation consoles, the only one with a GPU that has the necessary operations is the xbox.
That said, just because the XGPU has the necessary operations, does not mean the xbox is fast enough or has enough RAM to run Doom3's engine at a comparable detail level to a high-end PC. Of course it does not. However, that does not change the fact that, in principle, his full lighting equation can run on the xbox GPU.

You can use Flipper's dependant read to do DOT3 when one operand is constant, ie. you could do distant lights with it (like sun and stuff).jarrod said:
Doom3 however uses only local lights, and for this case you're stuck with the same kind of texture-combiner DOT3 emulation that you would do on PS2 - requiring several texture stages (multiple cycles per pixel) for one DOT3 operation - needless to say this would be quite slow.
The other problem would be that pretty much all geometry processing(from lighting to animation and volume shadow processing) would have to be done on the CPU, and Doom3 is mostly a CPU limited application to start with.
Actually GC's dependant read is a little more complex then EMBM though.aaaa0 said:

GC can run Doom 3 almost with the same Xbox quality. No doubt about it. GC can run Half-Life 2 either, maybe even better than Xbox Impossible is nothing.
But both GC and Xbox can't do MGS3 and ZOE2

No it does not, not completely. Read what Faf wrote above. Read what ERP wrote here:
