Cloth Physics

Post » Wed Mar 09, 2011 9:59 am

I've seen a lot of threads on here talking about realistic cloth physics. People say they want it, and people say they won't get it. But has anyone ever considered the http://elderscrolls.com/skyrim/media/screenshots/dragon-approach/ screenshot?? Look at how the animated loin cloth is swaying. Shouldn't that be evidence enough that there will be cloth physics in the game? It won't be as detailed as clothes rippling in the wind, but in my opinion, the loin-cloth looks provides enough evidence some degree of cloth physics will be there. Sorry if this has been discussed a lot earlier, but it's just an observation I made.

A more telling image is the image of the cloaked man walking through the town in the trailer. You can he his cloak swaying.

Try to look at the trailer (specially the fighting sequence), the characters move swiftly and the clothes don't look to have physics.

Maybe we'll have some cloth physics for flags, but thats it. : http://elderscrolls.com/skyrim/media/conceptart/whiterun/ - there are some flags in this concept art

Nice observation. Could have been attributed to another thread though. :shrug:

Yea, it might be too taxing on the CPU.

I doubt those are actual cloth physics. The can be imitated through good animation. Look at AC, they do very good animation work, but to my knowledge it is just that, animation. Real cloth physics take a ton to render, that's why you typically only see it in CG trailers and stuff like that.

I think we could make a difference between *real* and *fake* cloth physics.

Real are those ones done with Havok Cloth or PhysX. Fake are those clothes who are static, but that moves according to the player movements. I've seen tons of those fake physiqued cloths in mods (even for Morrowind), and that is what I expect for Skyrim (also because cloth physics doesn't seems to suffer from clipping, and I've already seen clipped armor in a screenshot).

They're a nice approach, but I don't expect them to be not even near of http://www.youtube.com/watch?v=wcds8eY93Zk cloth physics quality.

I've looked over what examples we have of moving cloth from the trailer and I gotta say, I've seen no evidence of cloth physics yet. It all still looks plastered to the skeleton to me. Neither has Bethesda said that they are using any cloth physics modules. They've said they're using Havok and Havok Behavior, but never have they mentioned Havok Cloth. So I'm guessing it's very unlikely we'll be seeing any.

As for the comment about physics on the flags, probably not. They'll probably just be animated to look like they're blowing in the wind at best.

or attributed to seeing threads pop up on it all the time, and having that screenshot as my desktop.

Not at all, but look at the screen. the character is still, and the cloth is too the side. I'm not saying they will be on every piece of clothing, but it could be on particular items (like a cloak or loincloth) where it would freely hang.

His legs are also bent. Notice how the angle of the cloth matches the angle of his legs.

Bits of clothing may have cloth physics as well as some hair styles. We don't really know for certain just because a full dress doesn't.

That's true, but would that mean every time you're standing still with that piece of equipment attached it will always be cocked to the side?

Yeah, SOME, 2005 hardware is nowhere capable of doing physics clothing, heck, even PC 2011 hardware can't make it, for all those NPCs rendering at the same time.

this shows some clipping, proving that some of the clothing is static, which is quite obvious

I don't know about anyone else, but I don't see any way to determine any sort of animated movement from a static screenshot.

Why so much emphasis on the 'some'? :huh:

This seems most likely to me.

Well, consider his stance. His knees are bent with his feet apart and his left leg forward. A classic combat stance. Spreading the legs apart would move one side of the cloth with one leg and the other with the other leg. So it's being bent forward and to the sides because of the position of the legs.

Because its crazy to think every bit of clothing would be dynamic.

It looks to me like the loincloth isn't swaying, but rather that it's moving with his legs, if you notice, it seems to be bent at the same angle as his legs, which leads me to think that it doesn't have physics, it's just physiqued to move with the legs. Nothing I've seen of the game seems to indicate cloth physics to me, admitably, the only gameplay footage we've seen is from the one trailer, still, going by that, it doesn't look likely to me.

ecause its crazy to think every bit of clothing would be dynamic.


I'd argue it wouldn't need to be anyway, if it's just a plain shirt, any physics it might have probably wouldn't be too noticable anyway, it's with things like cloaks or robes with large sleeves that tend to hang down that you'd want cloth physics, and while admitably we haven't seen anything to that effect, I still say that nothing we've seen seems to suggest that cloth physics are used on ANYTHING

realistically, it would still be pointing downwards because there shouldn't be any forces acting on the cloth besides gravity (maybe wind but I'd be surprised if that had an effect). But transitioning between an idle and an "at arms" stance would cause it to sway. There is really no way say for sure, but to me, this screen at least gives me some hope

That's just it, though. If it is tied to the legs as I think it is, gravity has no influence on the cloth whatsoever. The only influence on the loincloth is the position of the legs. It moves as they move. Just like it was done back in Oblivion. They may have it looking better, but it's still works the same.

I can see your point, but i believe footage is both too short and discontinuous to draw absolute conclusions.
Consider:
- Cloth physics are usually very taxing on the hardware.
- Todd mentioned Betehsda using both Havok physics and Havok Behaviour. Havok has another module specifically dedicated to cloth - not surprisingly called Havok Cloth - http://www.havok.com/index.php?page=havok-cloth. There has been no mention of it whatsoever.

No physics.. :cry: Oh well, guess I can live without it, same can't be said of my Skyrim character though.

But it's too early to say! They could easily add cloth physics to every cloth in the game.
