Quake TRUFORM demo - check out my screencaps

[GL]

First off, if you're an ATI user, you can download and run the demo here. Not sure if it works or not with Nvidia cards.

Here are some screencaps I made to demonstrate the 4 different levels of tesselation.

 

[GL]

bump, I know some of you will be interested! I want to know if this works on Nvidia cards.

 

[kami]

Doesn't work on my GTS.

 

[Karno]

Does not work with my GF3.

 

[Muerto]

Then I'm assuming it wont work on my MX.

 

[pidge]

Is it just me or do the pics look kind of ugly and deformed? Are they going to improve on this cause this looks horrible. I hope they do improve on this.

 

[GL]

No it's just you pidge

Actually on second observation, I think the deformity you're probably referring to is in the actual model itself. I think the guy's head looks weird but it looks weird in the truform-disabled picture so it can't be the truform that's causing it. Of course, the screencaps don't do it justice if you can't see all 360 degrees of the model.

 

[pidge]

Oh

 

[GL]

BTW, the guy that made this demo is 17 years old. Been programming OpenGL since he was 12!!!

 

[Adul]

I would like to try it out on another game

trueform is ati only folks. er at least that's what i read. the pics ive seen before looked real nice.

edit: better pics (not crapping) can be found at gamespots article which really shows off the tech.

 

[pidge]

Got a link? The grey models looked nice but I want real models from real games like that Quake models. Thanks.

So ATI is managing to use their TRUFORM technology on updated drivers with existing cards huh? Gee, I have an ATI All In Wonder Radeon, but too bad I've only got a P2-450. The images sure look nice.

 

[GL]

For speculative purposes, a level of tesselation of 2, allows my PIII 960 + AIW Radeon get > 30fps on this demo. So if Nvidia can emulate this via drivers, I don't think you'll be looking a very good framerates. Considering I'm getting 30fps with two figures and black background, I can only imaging how terrible the performance would be in an actual game environment.

Going higher than a tesselation level of 2 brings my rig to its knees - single digit framerates around 5 fps.

Without truform, I can pull 500fps on this demo.

What's wierd if that as the level of tesselation increases the framrate decreases EXCEPT on level 4 where the framerate jumps up again!

 

[GL]

pio!pio!,

That's a glitch. It's a glitch in the framerate counter. Level 4 is dead slow (~4 fps). Doing the screencap must throw off the framerate counter's accuracy.

 

[puffpio]

After a certain point, tesselation starts to make everyone look gooey ;P

I wonder if you tesselated an A-Wing if it will come out looking like a popsicle

 

[BD2003]

They all basically look the same to me once textures are applied. Tesselation lvl 1 or 2 seems to be the most youll ever need. I say the extra polygon processing power should go to more detail, not to smoother curves. I'm not impressed.

 

[randomlinh]

considering this isn't quite exactly from ATI, this guy is just playin w/ it, i wouldn't use this to judge truform.

 

[BD2003]

Either way, it works as its supposed to, as you can see by the wireframes. I doubt if anyone was shown a model tesselated with truform after textures are applied that they could really tell the diff in blind tests.

 

[arod324]

Well, also... since the truform isn't in thehardware... it should be using the software, which would mean it SHOULD inherently be slow. It's just like transform and lighting, the hardware is much better than software. So I'm guessing that having hardware that can do this, will improve the framrates GREATLY.
Also, is any one else having problems with viewing the EMBM ones?

<< trueform is ati only folks >>


From the AnandTech article on TRUFORM:


<< One thing to note is that TRUFORM technology is not ATI specific by any means: it is ATI's implementation of N-Patch technology included in Microsoft's DirectX 8 and OpenGL. >>

 

[GL]

This guy recompiled a few DLLs to get Quake I and Unreal Tournament using TRUFORM. Go over to www.rage3d.com forums to see his screencaps.

 

[BD2003]

Hardware or not, its more polygons. Likely handled by the t&amp;l unit, but there will come a point where even the t&amp;l cant keep up. Seeing that the radeons T&amp;L isnt as good as nvidias, lets hope nvidia can come up with a similar tech (likely, considering its not proprietary), or ATI can get a better t&amp;l unit into the next chip.

Those pics looks funny to me hehe
