Carmack Shows Off the id Tech 5 Engine 104

Posted by Zonk
from the phenomenal-cosmic-power dept.
MojoKid writes "id's keynote address from this past week's Quakecon featured John Carmack revealing details of the id tech 5 engine. For more on the subject, GamesIndustry.biz has an interview with id developer Steve Nix about the project. 'I know that when we started working with Splash Damage on Enemy Territory they wanted large, detailed outdoor terrains, and they had some ideas on how to dynamically load the textures and everything, and John [Carmack] said, 'Why don't we try this new approach and make the entire terrain one massive texture, and then just load blocks of texture in dynamically that you can see at any one given time?' So John did the initial work on it, got it up and running, and it just so happened that that work was the basis for what we have in id Tech 5.'"

Maybe it's just me. The textures don't pop, and I didn't see much in terms of depth of field or motion blurring or ambient lighting and occlusion effects. I guess we'll have to wait and see.

          You're missing the point of the tech demonstrations. Depth of field, motion blurring, and HDR lighting are current-gen features and are commonly featured in games out today. He was rather focusing on the amount of detail (80 GB worth) that was dynamically loaded, and didn't rely on old "hacks" (detail textures heavily repeated over a lower-res diffuse map, etc) to create the illusion of detail at an acceptable frame rate. And do so while keeping the engine both portable and fast is icing on the cake.

          That in itself is rather impressive. As an OpenGL developer, I'm no longer impressed by motion blur, volume shadows, and other textbook shaders/effects - I'm more impressed by this.

                      Shader results aren't really stored in video memory (unless you want them to be). They're output directly to the buffer based on a combination of shader code and base textures. Although the terrain may generate quite a bit of data, the resources it used to generate that frame won't be as large.

      Previously, you had to break up your textures into blocks and manually load them as the player moved into the area covered by those textures. This new technology allows you to create one large texture for the entire level and have the game engine automatically break up the texture into blocks and dynamically load them for you.

          That makes no sense whatsoever. I assume that by "line" you are talking about a row of texels. If so, then the orientation of the texture, relative to the view frustum, would have to align perfectly for a single line of texels to be of any use. If the frustum were merely rotated 90 degrees, then you need a column of texels, requiring fetching a single texel per line, resulting in massive cache misses. That is the whole point of breaking textures into squares, so that you don't loose efficiency due to or

      Memory footprint of these extremely large textures was prohibitive in the past. Originally this just wasn't possible.

      In the beginning, very small textures were all that could be used, and they were tiled everywhere. Ever since then, the workable size of textures has been slowly increasing...but the old habit of breaking things down into small(ish) textures remained.

      Technological advances and an 'aha!, we can do that now!' lead to advances such as this that to some might appear 'obvious', when in fact, since they hadn't been done before, weren't so obvious after all.

    The new texture technology that JC is demonstrating is fascinating but it really is a neat new twist on a much older trick - using tile-able textures to build up a much larger map, and then using overlays to take it further and make it less predictable.

    The basic landscape is built up at some reasonable level of detail for distance shots, with whatever geometry the modeller wants. Then the new techniques are applied to any polygon, anywhere. From the videos, there is a part where JC takes a texture, paints it on either side of the track. At this point, you can see that it really is square tiles - maybe 128x128 in the demo but I suspect it is arbitrary. Then these tiles are blended against other tiles and it's no longer so obvious what is going on. Then the overlays are painted on over the top to provide unique details.

    Now - the backend technology to cache all of these separate layers together must be pretty impressive to ensure that the view doesn't stutter as you pan the view. Using this level of organisation for the textures is akin to a smart compression routine, except you are identifying common elements right up front in the form of texture tiles, rather than trying to do it after the fact.

    I'd pay serious money to get my hands on the level editors for this tech - but I don't think my salary will stretch to a ID license fee.

      Sorry you're completely wrong. The mega texture itself is not based on tiles, that's just how they author it. It all gets baked out into a single completely unique texture at the end. So the initial large scale detail really is hugely detailed and extremely high res. Tiling is just a way of quickly painting terrain for outdoor areas, and then you can use an unlimited number of overlays (because they get baked out into the texture) to for example stamp out rocks and stuff to break up the surface. You can easily envision having a mode where you hit a key which brings a screenshot up into photoshop, you edit it however you want, and then project it back into the scene.

    You want to talk wide open spaces. Talk about the military simulator VBS or it's civilian counterpart OPF/Arma. These games may not look the prettiest but they have hundreds of square miles of seamless terrain. Enough so that many branches of the U.S. military signed up for it several years in a row. It has cross sim technology that allows it to talk to other simulators. But most importantly it run a insane resolutions and has view distances that would make a 747 pilot jealous.

    I really wish video game makers would get a little more realistic in their shooting games. Real (outdoor) warfare does not occur at 50ft, it happens at about 400 meters, that's almost so far that the guy you're shooting at looks like an ant. And that happens to be real life. Also, someone tell JC if someone is hiding behind a cinderblock wall and I shoot an 7.62 AK74 round at said wall and the bullet happens to land where someone is standing on the other side, they are dead. Bullets penetrate EVERYTHING except HEAVY ARMOR. That means if you shoot a house, someone on the other side of the house may get hit because the bullet penetrated every wall in the house. This is especially true for heavy machine guns (.50cal+) which can demolish a small house with a few dozen rounds.

    Also, and almost as important, don't make stupid doors that have a fucking golf ball holding them shut, I just destroyed a god damn super monkey spider droid with a mega doppler 5000 hand blastron laser fink and I can't open this god damn door because someone wedged a golf ball under it's flimsy wooden frame.

      There are some good ultra-real games out there (I remember playing a sniper game at E3 that actually modeled heart-rate and atmospheric effects (rain, heat, altitude, etc.) to calculate where each shot landed). The problem is that there is a very small market for them.

        That would be Sniper Elite [gamespot.com], a terrific game in my opinion. I don't think i've seen another sniper sim ever since. It had a great balance of realistic shooting and action.

          I remember back in the day, playing some supposed "ultra-realistic" combat game, "ultra-realistic" meant you get shot, u die... told a vet friend about it, he asked if you get trench rot in your foot in the game from being in trenches for too long... yeah. ultra-realistic = not so much fun.

            It is realistic in the sense it involves "real" sniping techinques - finding spots with cover, firing, relocating, watching your pulse and breath between shots. Then again, the missions are fun and well laid out with more than just long range shots - you go from assasination and cover missions to POW rescues. It is a very fun game, and well worth a fetch from the bargain bin.

      Modelling large areas is a lot easier if you get rid of the stipulation that it has to be pretty. Hell, Google Earth modelled the entire planet. I'm a programmer for Hegemony: Philip of Macedon [ldagames.com], a game which models the entirety of Greece, so I feel I know a few things about the topic. Tech 5 wouldn't work for us, for a few reasons, but it's still hugely innovative, and I have yet to figure out how he used MegaTexture on non-height-based-terrain objects.

      Regarding game design, everybody has to choose whe
  • Anyone else more excited about the mention of the $70 "every game that id developed" Pack that can be purchased on Steam, more so than the Rage demonstration?

    Maybe I'm just getting old...

    I'm sure Carmack is a great programmer, but his engines are specialized at doing one thing well at the expense of general flexibility. And the one special feature of the engine isn't even carried on to the next generation.

    Quake 3 had curved surfaces, no other major engine since then has had curved surfaces.

    Doom 3 had a unified lighting model, Rage does not. The unified lighting caused some pitch black areas and made it harder too make large outdoor type levels.

    Rage has unified texturing, which makes it harder to use specialized shaders on some surfaces. Other than the texturing and the much better development tools, I don't see much new?

      I think the major thing here is indeed the better development tools, with 3 architectures supported from a single code base, plus the fact that artists are given almost complete freedom. Given the fact that on most big games a lot of time is spent on getting the artwork done, I think this is quite an important improvement that many game studios are very interested in.

      What is wrong with Rage's lighting, it looks to me the environment and characters are lit the same way. Wasn't that what the Doom 3 engine was about? No more using vertex lighting on characters but lightmapping for the environment.

        Rage uses lightmapping on the environment. The only thing that really moved in the Rage trailer was the cars. The cars cast a shadow even if they are inside another shadow (from the same light source)

I have not yet begun to byte!
