<div class="IPBDescription">Commander there is an "Open RT" ...</div> German university created OpenRT, a <b>realtime raytracing</b> engine.
<a href='http://www.openrt.de' target='_blank'>http://www.openrt.de</a>
OpenRT is for raytracing what OpenGL is for rasterized rendering.
At the moment it requires 20 * 1,8 GHz = 36 GHz CPUs (or a special 1ghz CPU including a prototype raytracing chip) for a really low 4xFFA resoolution in Quake 3.
Then you have <b>realtime photorealism</b> with all volumetric and caustic raytracing lightning, sharp shadows and infinite reflections...

    Very nice! I like those chess pieces especially. I'm DLing the video now. <!--emo&:D--><img src='http://www.unknownworlds.com/forums/html//emoticons/biggrin.gif' border='0' style='vertical-align:middle' alt='biggrin.gif' /><!--endemo-->

    untill 1:20 the Quake3 demo video looks rather boring, I really would like interactive caustics, like dynamic reflecting water surfaces. <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html//emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif' /><!--endemo-->

    It does. I'd like to see a camera rotating round those chess pieces, that would keep me happy <!--emo&:D--><img src='http://www.unknownworlds.com/forums/html//emoticons/biggrin.gif' border='0' style='vertical-align:middle' alt='biggrin.gif' /><!--endemo-->. The lighting effects remind me of Unreal 3, quite nice.

    yeah, how is this different from pixel shaders .. or bump mapping .. or vertical sync .. or volumetric lighting .. or yatta ?

    I dont know video card terms <!--emo&:(--><img src='http://www.unknownworlds.com/forums/html//emoticons/sad.gif' border='0' style='vertical-align:middle' alt='sad.gif' /><!--endemo-->

    Raytracing traces every ray of light that passes through a scene, allowing for exactly-correct shadows, refractions, subsurface scattering, glow, and so on. Usually, raytracing is WAY too slow to be done in real-time. This is a real feat.
    And no, it's not a video card. :b

    I'm just wondering if it also does radiosity (aka:'reflected' light, such as if you're standing next to a matte white wall).
    And how many polys it can handle in a given scene, if all of them use pretty decent diffraction ratios? ^_^

    Neat. I'm glad somebody is already shooting for a RayTracing standard so the software will be ready for whenever the hardware catches up. :)

    Now watch as microsoft pushes to include DirectRT into dx10...

    [edit]
    This isn't just showing an engine doing Raytracing, its much bigger than that. Its setting a standard Ray Tracing language API for software vendors and hardware vendors to conform to, like what OpenGL and Direct3D do with today's current 3D cards.

    Raytracing is definetelly the way of the future. Now all we need is for ATI to get on the damn bandwagon and get to work on that 32Ghz video card chip. Sweet jesus that would be cool.

    If you didn't notice, a 1 ghz chip with special hardware would suffice.

    Of course, all that on a video card will take another year to happen, but my God... When it does...

    Wow, one step closer to the day where I can look at my monitor, then look out the window and say with all sincerity, "Man, those graphics suck."

    Nicely phrased, but nothing beats the outdoors. The sun the squirells.. ahahahah yeah right. Ray Tracing here we come.

    Wow, quake 3 looks awesome.

    That glass rabit really gets me though.

    Well, they have that Boeing example... 350 Mil [350.000.000] polies, but on a dual-cpu..... 1-3 fps XD
