ILM Now Capable of Realtime CGI 262

Posted by chrisd from the ilm-has-a-raleigh-mann-too dept.
Sandman1971 writes "According to the Sydney Morning Herald, specialFX company ILM is now capable of doing realtime CGI, allowing actors and directors to see rough CGI immediately after a scene is filmed. Actors on the latest Star Wars film watch instant replays of their battles with CG characters. ILM CTO Cliff Plumer attributes this amazing leap to the increase in processing power and a migration from using Silicon Graphics RISC-Unix workstations to Intel-based Dell systems running Linux."

      As for the term 'realtime', without a reference to what it is realtime against, it could mean anything. It's just how the language works, without a relation to something else, we have to assume something and hope the author intended what we assume.

      Just goes to show the inadequacy of languages, and why so many confusions are taking place in this world. No need to get upset about it though.

      Technically, perhaps. I think this is a great tool for directors and actors. Instead of having to wait weeks/months to incorporate CGI and see the interaction, it can be done in minutes/hours or as fast as the CGI people can splice things together. The director can give near-immediate feedback to the actor(s), which could really help the movie get done more quickly and with fewer costs in the long run. Think about it: changing the expression/pose/color on a CGI character is fairly easy. Re-filming live actors, especially with live fx, can take much longer and be more expensive (salaries for actor, director, film crew... lighting, film, makeup, fx expenses).

      Linux will be used on commodity x86 hardware for render farms by all effects studios, if not now in the near future. The reason for this. Bang for buck density. In order to render complex scenes you need a large render farm, the more faster units you have in the farm the better. It's cheaper to do this with x86 kit that anything else and the render software has Linux render engines written for it.

      More and more manufacturers are coming out with blade servers using x86 processors which will increase this density and likely increase the use.

      This is not saying that the studios are not running SGI kit for animation, modelling etc. Linux/x86 kit has a way to go to catch up there.

    You can get more processing power with the latter since it is cheaper (I would imagine even moreso with AMD) and easier to maintain. But not because it is inherently special or faster in any way.

Eventually his reliance on a small circle of friends was his undoing, as he was slowly replaced by more mainstream competitors.

    This is, largely, nonsense.

    These images are *not* realtime! A PC is not capable of rendering a CGI screen, in realtime, and merging that, in realtime, with a video feed, and then displaying that, in *realtime*.

    Say what you like about Linux, or high speed CPUs, or XXX vendor's high end GFX card - the architecture and the tools are physically incapable of this.

    If you look at the extras on the LOTR:FOTR DVD set, you'll see people walking around, with a camera on a stick. This *is* displaying real time camera images, merged into a low res, non final rendered, scene of the Cave Troll fight in Moria.

    A point of reference - the machine's they are using for this are SGI Octanes. Not Octane2s, but Octanes.

    They did that work around, what, 3 years ago? And the Octane, at that time, was only 3-4 years old.

    Can anyone show me a PC from 1997 that can manage that? Anyone?

    Despite the fact that the Octane is an ancient piece of kit, there is nothing from the PC world that can match it's capabilities.

    SGI have always been, and always will be, a niche player.

    You would be a fool to buy expensive SGI kit for a renderfarm - buy Intel PCs with Linux. Similarly, you would be fool to try and do realtime CGI with that same kit - that's a specialist task that calls for specialist skills.

    This article does not show that SGI is dying, or that they're being thrown out of the GFX workstation market.

    This article *does* confirm what is widely known - the once cutting edge ILM are now many years behind people like Weta Digital.

    Throwing around "Linux" and "Intel replacing SGI" sound bytes to try and get some news coverage for a dated effects house isn't going to change that.
    • A moden dual proc Xeon can come very very close to what an Octane was able to do in 1997. It's not the same thing, but it's close enough to do the job. Octane2 (with the right software) would be overkill, so here are the differences between a used Octane and a dual Xeon:
      The Xeon is new. That means you can get a good warranty and not have to worry about using used equipment.
      The wiz-bang factor. These days most SFX software runs on both IRIX and Linux. Even Apple's Shake does. So does all of the latest Linux
      • Good points, well made.

        As an aside, I would say that you can buy 2nd hand Octanes, phone up SGI, and they will give you a support contract - they will even check the machines over for you.

        The total cost will be a fraction of the cost of a new dual Xeon workstation.

        Again, this would be a foolish decision to apply across the board, but if you're doing the sort of effects work where the strengths of something like Octane are a bonus, it's a good solution.

        Yes, that's actually a very good analogy. Keep going, though. Is there really any computing task that involves 'hauling' more data, than rendering 3D video? Would you propose using an F1 to move a truckload of stock to the warehouse? Hm, the benefits of the F1's speed just went down the toilet, eh?

    I think its funny that two recent articles call Linux immature or maturing and that Novell gets bashed for calling Linux immature, but noone (as of this writing) makes mention of ILM saying the exact same thing.

    ILM's move to Linux has been a long and gradual process. "Linux is still maturing," says Plumer. "When we started working with it a few years ago, it was still in its infancy and a lot of things we took for granted coming from (Silicon Graphics') IRIX operating system just weren't there - supportive drivers from different graphics cards and other things. "It took a while to mature, but right now it's going extremely well."

    Carmack himself [slashdot.org] (on Slashdot no less) has predicted this would come to pass, due to the increasingly feature-rich and faster video chipsets.

    SGI laughed at the unassuming threat of the video chipsets, thinking that they would never be as fast as brute force. Even Pixar thought the same [siliconinvestor.com]. Boy, were they wrong though. You can set up a cheap-ass render farm for about $250k, taking up minimal space that can do the same job as a SGI render farm that costs a cool $2 million (Shuttle SFF PC w/ 3 gig CPU + ATI 9700). Of course, there's still the software side.

    The Nvidia's GeForceFX and ATI's Radeon 9800 both contain features that even through the marketing-hype has some real value to programmers out there. Just look at Doom 3. It will run well on some computers that are just 6 months old. Now, imagine taking 250 of them, as a Beowulf cluster!!1

      A high-end video card is used in a workstation for content creation. Final rendering, however, is still done in software (i.e., by the CPU), whether it's LightWave, Mental Ray or RenderMan. Don't waste your money on a Radeon for your render node.

        Erm, then why does SGI get all hot and bothered over the ability to add more hardware pipelines with G-Bricks? I think it's more that video cards are designed from the standpoint that you have to render in realtime, and your quality is what is variable, while SGIs are set up to render photorealistically, with time the variable.

      This is not a function of the CPU of the GFX card - they both play a part, but not as much as you seem to assume.

      For rendering, you need raw CPU power and middle of the road networking. A rack of dual proc PCs and a 100BaseT switch is plenty for most 3D people.

      For 3D modeling, a good graphics card and a strong PC behind it is what's needed. You want a card that can handle the polygons, can handle the textures, and has enough cache for all of the display lists. A 3DLabs Wildcat-series card on a modern PC is good enough for almost any 3D animato

      Yes, but:

      1. Subtract from that at least 10% of the CPU power, because that's going to have downtime. (This is probably a low estimate.)

      2. Add quite a few dollars for increased admin time. If you don't care when boxes die, this won't be quite so bad.
