Agreed; (Its also exactly what I expected to find with F3)
I kept mentioning this very point for almost two years
heh heh. Yeah, I think this is kind of your own personal campaign, though. There's a lot I'd have liked to see in FO3, but that wasn't one I was thinking of until you brought it up.
~However: Poly count makes a real difference. You can make a great looking low poly mesh but its still a low poly mesh and hence more limited in its "draping" of the texture onto the polygons. You can also do great tricks with normal maps and textures, but unless the object really is that angular, it won't look as good as a higher poly model in all situations. (like during deformations and certain lighting).
I see your point, but I think you could do just as well with some extra polys in the standard game model. At some point, I do think you come across a law of diminishing returns with polygons, after all. You're only ever going to need so many polygons to map out someone's face. That NVidia example you showed, probably doesn't really have all that many polys compared to what we already have in-game, I'd wager. The trouble I see with switching models out, in-game, is that you can only hide so much in a transition from first/third-person to a close-up of the face. Probably better to just increase the polycount in the face all around (likely wouldn't take up too many resources, really - it's mostly the textures that eat up your graphics card anyway.) I think, at least.
The fact that they can generate that Nvidia head demo on consumer hardware... kind of means they should in my book (so long as it falls within their target specs ~and especially since it would essentially be Fallout2 ~it would have just fit the series like tailored kid gloves IMO. :shrug:)
Honestly, though, as much as those talking heads were iconic in the old Fallouts, I think it's more an aspect of that sort of gameplay than anything else. That's not really the only isometric game I've played that had dialogue that was pretty much just like that. Pretty much any game where you can't already see the NPC's faces during regular gameplay, you're going to get a window that pops up with an animated close-up of their face. (Civilization - or pretty much any strategy game like that - as well as plenty of RPGs. It's really just a natural progression from the static portraits you'd see in other games from before that time.)
Really, I'd wager that if for some reason Fallout 1 was a first-person 3D game, that we wouldn't have ever seen those talking heads. (Though obviously only the lead designers would be able to confirm that.) I just think it's more an aspect of that style of game than something that's intrinsic to Fallout itself.
