different mapping techniques

[Legend]

what is the difference between the mapping techniques(bump, normal, displacemet, etc) announced for games and how can a gamer tell if a game uses certain kinds of mapping?

The Matrix: Path of Neo on PS2 uses normal mapping. it was thought PS2 couldn't handle it in the past. I want to know what to look for and will I notice a new mapping technique was used.

thaks.

I thought the ps2 couldn't do per pixel lighting they can probably use the normal maps but they won't give a real 3d effect, something simular to battlefield: vietnam maybe, but I don't really know

and to find out more about the mapping formats heres a few links

Bump Mapping

Relief Mapping

Normal Mapping

parallax/displacemet mapping

... per pixel normal mapping on the PS2.

Can it do it in-game though?

I can get a raytracer running on a N64 too, but you don't see N64 games using it.

... read that article.

CONCLUSION

We have shown that is possible to do DOT3 normal mapping very similar in quality to PC-style normal mapping ... w/out any additional effect on performance /normal mapping with ordinary shading/.

CONCLUSION

We have shown that it is possible to do DOT3 normal mapping very similar in
quality to PC-style normal mapping. Two methods have been presented: A
cheap two-pass solution, without per-pixel normalization, and a more expensive
four-pass alternative with per-pixel normalization. Both take advantage
of the hardware available on the PS2, more specifically the GS and the VU1.
This paper has also described how it is possible to integrate the normal
mapping with ordinary shading of non-normal mapped objects without any
additional effect on performance.

The Matrix: Path of Neo

Path of Neo does things on PS2 previously thought impossible. Normal Mapping, for example, was shown to be entirely feasible on Sony's aging machine via a cool spotlight hitting a brick wall demo.

... a brick wall game=tetris,as you speak.

Come on please PC this shows the child in you. Lets be real the man said Path of Neo.

Yeah and he said demo too. Show me a video with this dot 3 bump mapping in action in game and I'll shut up. And no a totally black scene with a single light source doesn't cut it.

I agree the shots of the game I saw sofar doesn't look like it uses normal mapping, and if they do it's not as defined as the pc or xbox can do

I don't think it Path of Neo for the PS2 normal mapping will look anything like Splinter Cell 3 on the Xbox. No way is that happening but I think they are trying to do something that really nobody whats to put in the time to pull off on the PS2.

Award for Technological Excellence

The Matrix: Path of Neo

We knew going in that The Matrix: Path of Neo had some great technological chops, but after seeing and playing the game for ourselves we're now convinced that the PS2 is far from being on its last legs. But how impressive is Shiny Entertainment's motion picture homage really? Well, how about some incredibly convincing normal mapping (previously thought impossible on the PS2), terrific bloom lighting effects, and cutting edge morphing technology all in the same game? Not enough for you? Okay then, throw in completely destructible environments, high-end reflection mapping, and some of the best depth of field effects that we've seen in this generation? Still not convinced? Then just sit back and gaze as the proprietary engine that Shiny has built allows as many as 1500 animated characters on the screen at one time. Yeah, we knew that would be the clincher.

The scary thing is, with all its technical achievements and impressive real-time performance, Path of Neo isn't even done yet. We can only begin to imagine what it will be able to pull off when it is.

If the normal mapping is convincing and not just used in simple scenes then call me a believer.

You mean embossed bump mapping for the PS2 version? :?

I really wish that this game looks every bit as good as IGN is making it sound. If it is it would truly prove that the PS2 is no slouch, just hard to program for.

Eh? Embossing? WTF are you talking about?
