Interactive Ray Tracing: A Better Way to Program 3D

[dahahaka]

thumbs up if you watched the whole thing too!!! :DD

31:34 he just blew his mind!

[UNCHARTED9444]

can the Cell Processor do this?

[dahahaka]

@UNCHARTED9444 i guess a intel core i7 SandyBridge 3.5Ghz can do it :)

[pwiattitto]

in the name of all that is holy!!! why doesn't he wear a microphone like any normal presenter?

that fading voice method is insanely annoying!

[Kazichia]

oh crap 1 hr !

Alot of advancement from the 1980s

I imagined a console with that in the future, and that made me remember the n64...

It had the silicon gfx thing, that made everything better, more acurate, and that just worked as expected... In the other hand, that quality came at the cost of low polycounts, low textures, and bad fps...

In the end, many ps1 ended up looking better, because the better models and texture made up for all the artifacts.

I can see the same thing happening with whoever decides to adopt the raytracing first.

Actually ray tracing scales better as the polygon count increases. So we'll have dense triangulations. A single triangle will be is smaller than a pixel. In this case, ray tracing makes much more sense.

[nintendomaniac64]

Wait wait wait... PS1 games looking BETTER?

I'm pretty sure it's universally established that the N64 was better than the PS1 graphically - heck it was getting ports of DREAMCAST games. (like Star Wars Episode 1 Racer)

@nintendomaniac64

I was a nintendo 64 fan boy, and still think it kicks the psx ass. But still many multi console games of the time, dispite the pixalized and crazy dancing textures, the psx had drastically better frame rates and more detailed models... But personally a still prefer the acuracy and solidity of n64 games better as well.

[nintendomaniac64]

@buzinaocara But my point was that there were ports of Dreamcast games on the N64 but not on the PSX! I'm not talking about ports between both systems, but from the Dreamcast! (Rush 2049 is yet another example)

And even though I haven't any proof, I somewhat doubt the framerate part. The N64 definitely had a faster CPU, and had the only 60fps game of that generation (F-Zero X)

Also some (if not many) N64 games ran at 480i instead of 240p with the expansion pack! (Rogue Squadron anyone?)

he says "uhm" all the time

[polypusher]

but he's probably much smarter than you... What does that say?

[squidcreek]

Raytracing itself is another form of trickery muck like rasterization. They're never going to actually simulate what 'really' happens. The photons travel at 299,792,458 m/s. Simulate that in PhysX?I think not. There are an infinite number of them almost. An the materials they pass though are not merely procedural textured layers, there's infinitely many electrons, protons and neutrons in there in there various arrangements. In gaming at least, I think rasterization will be the bigger footnote.

[squidcreek]

Still though, it is cool. The next console war if there is one will be epic. Consoles with integrated physics and ray-tracing, and HD sound and..who knows what else!

[infuzer]

"They're never going to actually simulate what 'really' happens."

... Your attitude will probably change within the near future I'm sure. cheers!

[squidcreek]

Ok, so they're going to simulate every single aton og a glass and every single photon of light that refracts through, or reflects off. NO, only for science maybe, not for games, that would be a retarded waste of energy and I\d be against it. It will be conventional rasterization, normal ray tracing (as in no light speed calculations, photon particle/wave, photon weight, electrons, muons etc...), spherical beam tracing or polygonal beam tracing. Maybe u didn't read my post properly.

[infuzer]

I did read your post squidcreek. To simulate is to imitate a phonomenon by means of something suitably analogous.

To simulate every single atom would not be suitable in this situation, no. But there will be simulations of 'what actually happens'.

I think we agree with each other, its just a question of definition.

[squidcreek]

I don't agree to that!

 just kidding : )

[automats1]

lol, thats not the case, what do you expect then? simulating real world? wait 200 years or more

[squidcreek]

Not at all. I'm just saying that this ray tracing hardware should be called what it is - a particular type of card that does a particular type of Math calculations well.

There will some day be a breakthrough in using optical chips (ie micro mirrors and lasers instead of semiconductor) for ray tracing, and that will be a real breakthrough.

someone's been going to school

[Westonci]

nice, cant wait for Caustic2

FYI, the algorithm itself is not gone into
