Motion Blur

[Gamingphreek]

This is probably a noob question but im allowed to ask one a day at max .

Why dont Nvidia and ATI and game maufacturers incorporate Motion Blur in games and on Video Cards. As im asking the question i obviously dont know but, is it becasue the video cards simply dont have the power to do that?

Doesn't it have something to do with the fact that most game engines these days use an interpolated frame animation method, so motion blurring would be very performance intensive and look funny to boot?

It's been a while since I read up on this stuff.

 

[Gamingphreek]

So not only would it make it look stupid but we dont have the graphics power in PC's like ours to use it?

motion blur in nfs underground makes the picture all blurry on my 9100, i assume this is sposed to happen? or is that the combination of motion blur+light trails??

For best results, motion blur should be viewed in a dark room (ie Movies). This allows the image to burn on your retinas for longer, and thus look smoother. I doubt either company would like to limit themselves by forcing you to "game in the dark" so to speak.

As for motion blur in games, it could work along with some form of Vsynch/frame limiting (motion blur should allow lower fps to look smooth, ie 24fps for movies), but again, best results would be in a darkened room.

If you have ever played moto gp on xbox it has motion blur. I was quite impressed with it as well. I believe it is more of a game software related issue rather than hardware related. The VC should have plenty of power though.

Just play "Need for Speed -Underground", it has motion blur, so I guess it's up to the software designers.

Motion blur was used in Prince of Persia: SoT if I remember correctly. Looked really damn good.

MotoGP 1&2 both have motion blur for the PC, and I do like the effect as well. It really adds to the feeling of speed when it kicks in.

I never turned the motion blurr option on in NFSU... does 30 frames per second look fluid with it on without feeling like you're going in slow motion?

Get a really slow LCD instead. Instant motion blur...

Well game designers have to focus on a lot more graphics elements that improve thier game other then motion blur. I have yet to see a animation system that is up to part without flaws that can be easily noticed in less then 10 seconds. So I don't think this should be high on thier list.

The major problem is that in FPS games a motion blurred image is dificult to aim at.

How can you motion blur stuff that isn't predictable? What if the object suddenly moves left but the blur predicted it to move right? That would be confusing as hell.

i've seen it in nfsu, princeop, and motogp. its neat, but i find it very distracting. I think its because the resolution is too high and the colors too bright to produce a nice blurry trail. this might explain why it looks good on a tv.

3Dfx tried it. It basically would take as much power to get it done as it would to render the additional frames, as you'd have to keep pumping the same pixels through the pipelines over and over.

Personally, I have not been impressed at all with motion blur used in games--just makes things look fuzzy.

GTA3 has motion blur if noone has mentioned it..

 

[ZobarStyl]

Yeah, GTA3 had it and it made me sick half the time...:thumbsdown:

NFSU's motion blur was fairly nice IMO ... frankly, I found that with it off everything just looked too "sterile" ... I mean, at supposed 200mph speeds, I don't expect to be able to read "Eat Uncle Ben's Rice" on a billboard.

Motion blur is just a lost of focus on an object that's moves to fast at a certain distance from your eyes. It's more like depth of field blur.

If something moves too quickly in front of you, you won't be able to focus on it and therefore, motion blur - though farther away it will either be too small or you will be able to focus on it, so no motion blur.

I don't think it should be implimented because it is just like depth of field blur and if we don't impliment that, then, we don't impliment a "motion blur."

Depth of field blur is also extremely hard to implement and shouldn't be done at all, because depth of field is again, just like "motion blur," - it's a loss of focus on an object that you aren't focussing on, only that motion blur is a loss of focus on an object that you can't focus on.

You need Actual depth for this these blur ideas to actually work and I think it would look terrible as it has already been implimented badly. Unless our eyes do it for us, then there should be no motion blur or loss of focus, because that is not how the world looks.

Video games should be more in tone to create a "real world" and not a movie experience.

For the motion blur on NFSU, do they use it all the time, or is it just when you use NOS? I understand what yoursaying but wouldn't motion blur allow us to run games at 30fps constantly, then manufacturers wouldn't have to worry about which video card is the fastest and they can start worrying more about image quality.

(Didn't the Voodoo 3 4 and 5's have motion blur support? Do the nvidia and ATI and Matrox cards of today support it?)

Depth of field blur is also extremely hard to implement and shouldn't be done at all,

? the author of RTHDRIBL implemented both with shaders in DX9 quite a long time ago with nothing but research papers to help him, how is it extremely hard to implement?

Motion blur in NFSU is used all the time and then when NOS is used, everything is just a blur to simulate light speed.

30fps sucks ass.

The Voodoo 4/5 was capable of motion blur and depth of field blur, but it had to be software enabled. I'm sure that cards from today support it.

I don't think it would look right, so it would be pointless to implement - that reason plus the idea that it could rob performance.

Not everything has a blur to it like in NFSU. Only certain things and that is releated to distance the object is from you, where your eyes are focusing, and how fast the object is moving.

3dfx had implemented that stuff back in 2000
