G80 = 1st real fruit of NVIDIA takeover of 3Dfx ???

[Siskods9]

So if the G80 has been in development for 5 years or so... Is this new architecture the first real fruit from the NVIDIA takeover of 3Dfx all those years ago???

Is there more than a little voodoo in the G80 ??? :p

EDIT: Mods perhaps I made a mistake posting in this forum, maybe it would be better placed in the Geforce 7 & 8 series section? Apologies for that.

8800 may contain major 3Dfx tech, but it's not the first use.

From inside the company, the NV3x (FX 5x00) was the first significant byproduct of the 3Dfx IP we bought. Hence the FX in GeForce FX. Additionally, the Texas (Austin? i forget) ex-3Dfx office was working on nForce2 when I worked with them.

^ wow you worked with them, do tell more :)

yes, please do. (nana2)

He can't tell you much because I think he left during nVidia's lowest, darkest days of the GeForce FX 5800 ULTRA / NV30.

I am more than sure that the last remnant of 3dfx technology is in the GeForce FX line of cards. I'm also pretty sure that the rumored Voodoo Rampage is probably in fact the GeForce FX 5800 Ultra, and then they updated that with 256-bit mem and all that (5900 Ultra). I doubt there's still any remnant of 3dfx technology in GeForce 6 series, let alone 7 and 8..

I think 3Dfx lives on inside each and every one of us.

[SH64]

I read it took 4 years & $475M to develop.

but yeah i think much of 3DFX tech is inside that core.

So true

you are wise, my son

Heh, where do these questions come from? What product/patent did 3dfx ever issue that has anything to do with G80? Nvidia had a bunch of engineers before the 3dfx takeover yuh know? Also, I think some of the main guys on the G80 project were ex-CPU engineers. Every time Nvidia does something this 3dfx question comes up - it's like a living legend :)

I think its because 3DFX was developing free AA before either Nvidia or ATI ever thought of it. Since this is the first time we are able to increase higher forms of AA without any large performance hit it makes people wonder if Nvidia has finally adapted some of the things that 3DFX was working on.

They also were talking about things like true motion blur which we still don't see today :p But actually I think Crysis uses it.

[superklye]

Motion blur like in GoW when you rotate the camera quickly? Or something different?

[jAkUp]

I think they were mainly talking about characters that moved on the screen... was it T-Buffer they called it? Or something like that. For instance, a character moves across the screen quickly and has motion blur applied to him.

[superklye]

Ah, gotcha.

Object-based motion blur IIRC. its being used in Project Offset too.

& yes i have to mention that motion blur is used very well in GoW. i expect many other UE3 titles to do it the same way.

I always thought that T-buffer motion blur stuff was like the AA, rendering the image multiple times and offsetting the renders so the image is appearing in more than one place at once, which is essentially motion blur, since true motion blur on film is simply the image being present in more than one place on a single frame of exposed film.

[RejZoR]

Yes, T-Buffer stored more frames and then blended them to simulate bluring effect.
