    why is everybody so excited about getting rid of spinning media?

    Because the spinning media is what makes my modern Dual Core computer feel as sluggish as an old Windows98 laptop. Access time on HDD is basically the single largest bottleneck current day computers have when it comes to responsiveness. It just doesn't matter how fast your CPU and GPU are when they are both idling waiting for the HDD to catch up.

    I know I'll be keeping my movies and files handy right here, thanks.

    Streaming a DVD quality movies already works quite fine with a basic 2mbit connection, now uploading it will be a bit troublesome and I don't think it is that easy to get 1TB of online storage for cheap, but at least in principle, it makes perfect sense to have stuff stored in the "cloud" and only cached on your drive. Not because buzzwords are cool, but simply because you want to access your data from different devices anyway, so having a central server instead of manually copying stuff around is a lot more comfortable. It can of course also acts as backup and version control.

    Now moving your apps into the cloud is a complete different thing and I wouldn't recommend it for most things, but storage has been non-local on a file server in every larger network already anyway, not a big jump to scale good practices to the Internet.

    All game engines have a renderer behind them, by it OpenGL, DirectX, etc... these API's do not reduce detail/etc.

    So what? That doesn't stop you from using space partitioning, LODs or other tricks. You simply don't need a million polygons to render a round sphere, a geometry shader can do that for you. It would sure be nice if you could, but if given the choice of implementing LOD or throwing away all your graphics hardware and software and doing it all over again in raytracing, I think doing LODs will probably be the better answer for quite a while.

    We are talking about O(dynamic objects) here, not O(triangles) .. which is why many videos of realtime raytracing since 2007 or so have included .. dynamic scenes .. such as the one linked to in this article .. which I guess you didn't watch.

    We are talking about games here, not about moving a single object around. Games have hundreds of objects and easily thousands of particles flying around all over the place, they also have vertex shader running the bone deformation on every organic looking thing around and a physics engine crumpling your car. That is quite a different thing then having a tech demo where one object gets moved a little a bit.

  7. Re:Rigid thinking on Wolfenstein Gets Ray Traced · · Score: 1

    One of the advantages of ray tracing is that you don't have to build everything out of triangles; you can have real continuous curves.

    Real continuous curves are pretty much useless for gaming, as they are an artificial restriction that really doesn't help much with anything, unless its CAD or you want to fit your game into 64KiB.

    It's analogous to the difference between raster and vector graphics.

    Vector is only good for low detail stuff like logos, if you want to get photorealism you go with pixels.

    Exactly, the thing with DLC is that it comes in so small packages that it is practically impossible for it to do anything meaningful. I don't care if it costs $3, $5 or $10, give me back the old $30 add-ons that actually felt like proper extension of the game and where long enough to actually do something. Most DLC just feels like an additional level, instead of an additional small story arc.

  9. Re:So many on Wolfenstein Gets Ray Traced · · Score: 1

    LOD doesnt absolve the scaling problem. Lets say you have a system set up for 25% LOD versions of the geometry, but then double the number of polygons in the geometry.. well you have also doubled up the polygons in the LOD versions as well.

    A LOD only needs enough polygons to look good on screen, if you add more detail that isn't visible from a distance, the LODs polygon count doesn't need to increase at all. In practice this basically means that you only need to render polygons larger then a pixel, as anything subpixel is lost anyway, and if you look at the tech specs of a modern GPU you'll see that they can already render more polygons then you have pixels on the screen.

    I think the biggest one that you missed is the much higher cost of anti-aliasing.. for rasterizers, anti-aliasing techniques pretty much fall right out of it..

    There are post-processing algorithms for faking anti-aliasing, already used in current day console games. Might not look as pretty as real anti-aliasing, but might be a viable trade-off for raytracing.

    for rasterizers every doubling of visible geometry doubles the computational resources required.. but for raytracers increasing geometry can almost be shrugged off as inconsequential...

    A raytracer is only fast for static scenes, if you have something dynamic and need to update your space partitioning for the raytracer, the whole O(log n) magic kind of falls apart.

  10. Re:So many on Wolfenstein Gets Ray Traced · · Score: 1

    A rasterizer would have to deal with each and every triangle in that chandelier.

    Or it could just do LOD with a geometry shader on the GPU.

    When the polygon counts do get high enough, there will be no looking back.

    The problem is that you don't just want high polygon counts, but high polygon counts for dynamic objects. And ray tracing itself has its strength in static objects, as soon as stuff moves and deforms, ray tracing runs into quite a few issues, not necessary unsolvable issues, but that demo was rather lacking in that aspect as the particle system looked like complete garbage compared to todays games.

    Or to put it another way: The job of a tech demo is to blow me away, not present something that needs a server farm to run and looks worse then a $200 Xbox360.

    Everybody agrees that ray tracing is just awesome

    Actually, no, the raytracing shown in that demo isn't awesome, it is rather primitive and ugly. You can render shiny spheres with it and static high polygon objects, but basically nothing else.

    The stuff that you need to make graphics look good is global illumination and that demo had none of that. Todays games on the other side start to get there, you can already find realtime ambient occlusion in some games, you can get soft shadows and there have been tech demos even showing realtime photon mapping. And of course there is a lot of post-processing trickery like crepuscular rays that make things look good.

    At a certain polygon count raytracing may have advantages and for many of the advanced global illumination stuff you also end up tracing rays in one form or the other. But the demo shown demonstrated none of that, it was basically your grandfathers primitive ray tracing. Not exactly impressive by todays gaming standards, especially since it even failed to get basic stuff right, like the particle effects which looking ugly by last-gen standards.

  16. Re:NOT real HDR. on HDR Video a Reality · · Score: 1

    Nope, it's an interesting gimmick, but unless HDR displays enter common use, just a gimmick.

    HDR is in large part about post processing, not about reproducing the difference in brightness, as no monitor in the near future will be good enough to say reproduce the massive light from the sun. So there will always be a cut-off, it just might be a bit further out then it is today. Post processing on the other side benefits immediately from HDR.

    One thing however missing even with todays displays is just shipping the HDR information in the first place. Tone mapping is something that really should be happening on the client, instead of just receiving the already tone mapped non-HDR information.

  17. Re:HDR? on HDR Video a Reality · · Score: 1

    Can anyone give a brief rundown on what HDR is?

    Imagine an image not using an integer from 0 to 255 to store color information, but a float. That is basically the core of HDR (in reality it might not be a real float, but just a large integer). This allows you to save the difference between looking in the sun and looking on a white sheet of paper, so instead of both getting the value 255,255,255 (aka white), the paper will end up with a small number and the sun with a really big one, properly recording the different amount of photons each of these throws at you.

    In practice, as there are not yet cameras that can directly capture HDR, this effect is achieved by stacking multiple different exposures from a normal camera to reconstruct the higher dynamic range.

    What you see on Flickr and in this video under the label "HDR" however is not really HDR. As the video you get is a normal one, clamped to the old range of 0-255, by a process called tone-mapping. This works by analysing the HDR data and then basically giving different brightnesses to different areas of the image, so that no part of the image ends up under- or overexposed. Different tone mapping algorithms will give you different results, so often you won't get to see a more realistic image, but one with overly bright colors and unrealistic contrast.

    A Microsoft Windows or Apple OSX release is just the OS, a Ubuntu release is the OS *and* basically all the software you'll ever use. Fast release cycles simply means that you will get new software and hardware drivers quickly. On Windows and OSX software and drivers is updated independently from the core, so it doesn't matter if the OS is a few years old.

    NCsoft is directly responsible for that. If there wouldn't be NCsoft he technically simply couldn't play LineageII, it is as simple as that. NCsoft is a necessary link in the causal chain that caused him to play to much of this game, of course there are also other elements that caused him to play to much of the game (easily addicted personality, etc.), but none of that makes the part that NCsoft played in his addiction go away.

    Now of course if they are legally liable is a completly different matter, with cigarettes for example we get all those warnings about direct heath risks, but I don't think we get any warnings about potential addiction issues, so it might very well be that addiction is simply an accepted side effect that doesn't need to be warned about in a legal sense.
