Thanks for posting, I moved it to the news discussion board and made it front paged.

Method of lighting.

Raytracing is probably the industry standard method of lighting in 3D/CGI movies.  Like toy story etc etc

My cousin showed this to me a while ago. Quake 3 arena with Raytracing: http://www.youtube.com/watch?v=bpNZt3yDXno

Some pretty technical answers from Cevat there, I highly doubt that a dedicated card would take off for the typical gamer, take PhysX for example

An interesting arguement between rasterisation and ray tracing..going by industry position, although i can understand why, Cevat could be the wrong man to ask his perspective on ray tracing since so far we've seen Crytek mainly focus and succeed immensely on open-large environments. Where games developed by ID or Epic focus on closed, indoor environments which is the prefered theme for building the fundamentals of next generation technology since it requires less output from hardware compared to open environments.
Carmacks opinions seemed alot more detailed and influential than Cevats by every mean.

To put it simple: Raytracing = Photorealism (not really, but you get the point)

Raytracing will eventually be used in games, it is inevitable. But for now, I don't see it happening.
While ray tracing is great, I think there is more important tech we need to implement, like ATI's tessellation engine.

Agreed, The current lighting implementations do me fine, but the Tessellation engine allows everything to be more detailed, while using far less polygons, which means the left over processing power could be used for better and smarter lighting effects.

You can read all the interviews and get it down to one line ...

current hardware is not designed for ray tracing ...

But the notable thing is that the current hardware could use a bit of Rasterisation and Ray Tracing in combintion to give out some nice effects, basically the only thing I really learnt is that Ray Tracing is not the best for every feature in a game, while Rasterisation isn't good for others, so a mixed mode would yield more performance and better image quality.

What Intel is forgetting is that raytracing with dynamic scenes will perform very bad and as the "new" big thing in games is physics them raytracing is not really the best render tech to use for playable frames. Until now i don't see anything about raytracing that seams to be better them rasterization, shiny balls are possible with shaders as also perfect mirrors.

What i aspect is for rasterization to stay 5 or more years and them raytracing will be introduced down the road but as a hybrid ray/raster API.

For me realtime radiosity as invented by geomerics and lightsprint are better.

I saw this video on youtube. One dude connects 6 PS3s together and manages to do real-time ray tracing.

Yeah i saw that too. Wasn't it 8 PS3's, though?

[tolgapaksoy]

Nope it's even 3 PS3s, so less!
