Intel show Far cry in ray tracing/So to speak

[Nemesis 1]

Can't wait for larrabee.

[Sylvanas]

Sweet, another major player in the market would be awesome.

 

[Griswold]

Nothing to get excited over just yet. This wont take off until the big players of the gaming industry chime in. Could as well end up in another (discrete 3D) debacle for Intel.

 

[Nemesis 1]

Well intel is buying up companies to make it happen . They just bought a game company . I don't believe for a second intel will drop the ball on this with the $$$$ their spending.

Ray tracing is not the solution :! anyways we need a 100 core cpu $200~ before ray tracing become an a real option. The clip intel has show is generated on a cpu that isn't even out in the market. 20core + CPU at least.

 

[postmortemIA]

intel is already major player, they are reason why gaming sucks for 50% PC owners that have onboard graphics.

Even S3>>intel

Like Carmack said in a recent interview, Intel needs to show a win with next-gen stuff that shows ray-tracing is worthwhile and feasible, not all these old games and engines using ray-tracing. That just shows the extra overhead and expense involved with ray-tracing is acceptable for old titles, which is like software/emulation of old games on current hardware. I suspect Intel snatching up gaming studios might result in some tech demo, but its still going to take time for other devs to get onboard and Larrabee will need to be competitive raster-based GPU regardless if it releases in 2009 as suggested.

It looks like the ray tracing demo was done with FarCry2, not FarCry...

I don't really understand what intel is supposed to be showcasing in that demo.

Is their CPU somehow hardware-accelerating part of the 3D engine? Or is that a demo of what their new discreet GPU can do?

Also, how does current HDR lighting compare to this ray tracing stuff? I always thought that radiosity was the ultimate in lighting/shadows, which is also supposedly better than simple ray tracing. Doesn't the current HDR implementation already use radiosity?

I know that ray tracing can make things like glass look incredible, and can create more realistic shadows. The thing is, radiosity does all that, plus it shows how the light reflects off diferent colors and changes its hue accordingly.

Ray tracing = CPU whore :!

More Core = More FPS :!

Example :

3x PS3 http://www.youtube.com/watch?v=oLte5f34ya8

Some little BS me think but who knows Intel may be right :

http://blogs.intel.com/researc...ytracing_in_your_p.php

Intel wanted Crysis to run @ 60FPS on 16 core CPU but currently it need 32 CORE to 64 CORE :!

Ray tracing has a 4 year performance lap :!

So a 4 year old engine like Quake 4 will run at ultra smooth frame rate on a 8 core CPU which isn't out yet but you can get the skull platform 2x Quad core.


Ray tracing is suppose to woop HDR.

Ray tracing basic Algorthm :

For each pixel in image {
Create ray from eyepoint passing through this pixel
Initialize NearestT to INFINITY and NearestObject to NULL

For every object in scene {
If ray intersects this object {
If t of intersection is less than NearestT {
Set NearestT to t of the intersection
Set NearestObject to this object
}
}
}

If NearestObject is NULL {
Fill this pixel with background color
} Else {
Shoot a ray to each light source to check if in shadow
If surface is reflective, generate reflection ray: recurse
If surface is transparent, generate refraction ray: recurse
Use NearestObject and NearestT to compute shading function
Fill this pixel with color result of shading function
}
}

If your interested in ray tracing you should check out pov-ray. Really neat 3d graphics program that can render ray traced images that you create.

 

[BFG10K]

It's not even clear what Intel were showing in that demo. Are they saying they were rendering Far Cry 2 in realtime using ray tracing? If so at what settings, and at what FPS?

For all we know it could've been done by an offline render.

 

[Munky]

I don't see what they're trying to show either. I don't think that whole renderer uses raytracing exclusively... they're probably just using it for some shiny reflective/refractive surfaces, which otherwise could be done much more efficiently and look similar using rasterization and pixel shaders. I hope Intel is not designing Larabee around raytracing, because that would be like throwing cash into a black hole - you won't see any results no matter how much money you throw at it.

That is not a fully ray traced scene.
I do ray tracing every day using programs like vray and can see lots of things that are rendered wrong if that was fully ray traced.

Image two:
fire lighting and color not affecting ground.
smoke not showing shadows
blades of grass not casting shadows
man thats on fire not affecting lighting

Image three:
grass not casting shadows, the grass in the distance not the one nearest player.
The grass nearest player is shadow mapped, thats not raytracing.
bump mapping non-existant
clouds in sky not casting onto ground
Color of sky not affecting environment


It looks like all they did was ray trace some shadows on some scene items.
Thats nothing that any current game engine can't already do, but with other means, that are actually faster.

This is real ray tracing:

When Intel can do that in realtime call me !

 

[tommo123]

eek! those looked awesome! some look real.

gaming through environments like that would be... well, weird tbh.

 

[GundamSonicZeroX]

Am I the only one that thinks that this blurry, small movie isn't a good way to showcase Ray Tracing?

Ah yes, you're right. Didn't check out the link but was just going on the title and their previous Q4 ray-tracing demo. Still, doesn't look as if that FarCry2 demo was rendered in real-time using ray-tracing. And as others commented, it still looks as if they've got a ways to go.

imo intel is as stupid as MS with their Yahoo purchase

RT is a "joke" and is PR for intel and it is designed to simply "showcase" Larrabee .. maybe in 10 years after Larrabee we will really "see something" .. they spend tens of millions on PR - this is no different.

RT will NEVER - ever - replace current game engines and intel is on Drugs if they really think so
--at the very best it will be used within current game engines

my take .. and i will *bet* anyone

 

[VRXJudge]

Well, realtime raytracing might be feasible many years in the future; it would take an inhuman modern array to render a playable raytraced scene.

Maybe they're not casting rays recursively. And it seems like they don't have dynamic lighting. Like others have said, I don't really see ray tracing or larabee being feasible because of inadequate computing power.

You mean like John Carmack was talking about?

 

[The Bakery]

Hi res raytracing with anti-aliasing and atmospheric effects can take upwards of an
entire day to render a single frame.

Real time ray tracing like that would take an unreasonable amount of CPU.

Maybe if we get quantum computers to the enthusiast market

yes .. and every Dev that has not been "bought" by Intel

i know BS PR when i see it .. intel is either nuts or brilliant
- i vote for "nuts"

'NetBurst' is here and we will see 10Ghz!!
:roll:

i'm really tempted to stick a Phenom in my rig - and pair it with NVIDIA graphics
:Q

So there!
