Tron Legacy: how the special effects were done

The author, Josh Nimoy, gave a great talk at last month's LA Hacker News meetup. Unfortunately, can't find a video recap.

What I love most is seeing how they go about thinking and producing the effects used for computers used by characters in the film! From the films that do it really poorly to the films that attempt something realistic, I always wonder who's in charge of it, how they think about it, what tools they use to create it, etc. For the films in which it's poorly done I always figure it's the assistant FX designer's kid who has 4 months experience in Flash. For the good movies I always wonder if they grab the DB administrator for all the film assets and ask him some nerd questions :) From the article: In Tron, the hacker was not supposed to be snooping around on a network; he was supposed to kill a process. So we went with posix kill and also had him pipe ps into grep. I also ended up using emacs eshell to make the terminal more l33t. The team was delighted to see my emacs performance -- splitting the editor into nested panes and running different modes. I was tickled that I got emacs into a block buster movie. I actually do use emacs irl, and although I do not subscribe to alt.religion.emacs, I think that's all incredibly relevant to the world of Tron. It's utterly fascinating to me that people have jobs like this.

  | grep '[o]s12' would have filtered out the grep process from the ps output. :)
  - rdtsc 16y ago
    It is a futuristic, more intelligent version of grep that understands the context in which it runs, and automatically filters itself out when it processes the output of ps ;-)
    - DannoHung 16y ago
      Or maybe there was an alias to grep that was 'grep -v grep | grep $*' or something like that. And they use ack for File searching cuz it's way better.

      http://jtnimoy.net/178/TRON_GFX_BR_07.JPG http://jtnimoy.net/178/TRON_GFX_BR_07.JPG seems to indicate plain old grep, not futuristic intelligent grep.

    When I saw that image, the first thing that came to mind was pgrep from the procps package. Using pkill would have crunched it all down to one line. Too bad they didn't use that. However, I must admit it did look pretty cool as-is.

  In that vein, I was way too excited to see Mark Zuckerberg hacking in Emacs in The Social Network. It's so rare that movies get this stuff right that when they do I can't help but smile.

    It was also pretty nice to see all those KDE 3 desktops in the film, especially since it were the historically correct versions for the timeframe of the story.
    - gaius 16y ago
      If you look at see what SunOS version the Grid is running, when Sam sits down at his dad's old workstation, it doesn't match up with the timeline.
      - arethuza 16y ago
        If you look really carefully you can see that it is actually running "SolarOS" not "SunOS". I paused one of the trailers at 1080p and captured the workstation desktop and I've been using it as a desktop background - quite a few people have told me that I really need to clean my monitor...

  I'm a fan of computer interfaces in film across the board. From the intentionally tongue-in-cheek 'Hackers' to the downright unintentionally awful and the occasionally vaguely bordering on something close to reality. I haven't seen this movie, but I'm actually impressed by what I see in the article. It raises the question, however, whether it's something that actually pays dividends. That is, when you employ any sense of reality in this specific domain, does anyone who isn't intimately familiar actually notice? Is the subset of people like ourselves who notice even worth catering to in such small ways? I know my mother, sister, grandmother, and most of the other people in my life wouldn't recognize if it was accurate or not and I suspect 95% of the audience falls into that category. On the other hand, small things can make a big difference, when you catch them. They're like seeing a loose thread on a piece of clothing that you can't unsee again. Or a stuck pixel on your LCD. For instance, I was watching a marathon of Roswell on Netflix this week (hey, shaddup -- I've never seen it before and wanted something awful to go along with feeling under the weather!). At one point, a guy says to another who is holding a revolver "you might as well just fire every bullet in your chamber!". Of course . . . a gun only has one bullet in the chamber at an time, as far as I know. Most certainly only one in a revolver. And it has bugged me ever since.

    I don't think he'd have saved any time doing a completely original interface based on nothing. Quite possibly, it would have taken him a lot more time to do something as visually compelling (for mom and pop) as that completely from scratch.
  - SimonPStevens 16y ago
    "I know my mother, sister, grandmother, and most of the other people in my life wouldn't recognize if it was accurate or not" I think each knowledge domain has it's set of experts that will spot mistakes in their own areas of experience. Every mother I know, when watching an on-screen delivery, will retort "that's not a newborn" when the babies face first appears on camera.

I would love to see some of these visuals make their way into xscreensaver... Unfortunately I have already promised I would take a look into the Apple II screensaver because it's not completely faithful to its 8-bit namesake. Besides that, this is completely beyond my modest knowledge on mindblowing visuals. I am more than a little embarrassed because I thought I could map the output of the Apple II screensaver to a curved surface to mimic a CRT screen on current flat screens. That was humbling.

One of my post-exit fantasies is to start a company that solves eccentric billionaires' (and casinos, Hollywood, and large corporations) crazy decoration problems, by designing new types of computer-controlled fountains and nontraditional displays, algorithmically-generated dynamic landscapes, etc.
  - pkteison 16y ago
    Why wait? Smart lights are DMX controlled, and computers control things easiest these days with USB, so google up DMX and USB and hit ebay and then write some code to have your laptop control lighting. Once you have a computer controller in the loop you can do almost anything. ("Color Kinetics" is one brand of interesting computer controlled light I have played a bit with. I'm sure there are many more options out there also.)

Prior to seeing it, I'd decided that, for me, the real 'test' of whether I could consider this a genuine sequel would be in the landscapes... Tron came out in 1982. Ken Perlin won an Academy award for his work on the procedurally generated textures (http://en.wikipedia.org/wiki/Perlin_noise http://en.wikipedia.org/wiki/Perlin_noise) used in the movie. The Mandelbrot set (http://en.wikipedia.org/wiki/Mandelbrot_set http://en.wikipedia.org/wiki/Mandelbrot_set) got widespread fame in August 1985, with that famous Scientific American cover. Tron just missed that graphical opportunity!

How mistaken I was... Yes, I'm really bitter about producers and artists who don't care to know anything about the history of their art. And they had the presumption to call it 'Tron Legacy'??

I've never heard of Houdini so I had to look it up (it's a purely procedural 3D animation package): http://en.wikipedia.org/wiki/Houdini_(software) http://en.wikipedia.org/wiki/Houdini_(software) Here is their demo reel: http://www.youtube.com/watch?v=leJks6ay4tg http://www.youtube.com/watch?v=leJks6ay4tg Apparently Maya, Softimage and 3DS Max are not the only players in this space anymore.
- oofoe 16y ago
  Sorry, small clarification: Houdini is actually descended from the PRISMS package developed by Omnibus Computer Graphics (one of the very first CGI studios (and actually still in business in Japan!)). SideFX (started by two of the original programmers) bought the rights to PRISMS when Omnibus (North America) went under. They opened for business in 1987 and have been going strong since! They have a number of "firsts" to their credit -- for instance, Houdini was the first major 3D package on Linux. Debuted in 1999, although I was beta-testing it before that. For procedural 2D and 3D graphics, there is absolutely nothing like it. However, it's hard for most users to understand, so its popularity has never been great. Anyone doing serious FX work knows all about it, however. (My old boss used to be CTO of Omnibus, in charge of PRISMS development.)
- wtracy 16y ago
  If you're interested in a FOSS application for procedural graphics, take a look at Povray: http://povray.org/ http://povray.org/ It has no (built-in) UI. Its file format is a domain-specific scripting language. :-D

sradnidge 16y ago
I didn't like TRON Legacy at all, but after reading this I'm going to watch it again. Several times even.
- rbanffy 16y ago
  The story is predictable, but, come on... It's like Star Trek (pre-2009 at least). You know it will probably not live up to your expectations, but you just have to see it anyway. BTW, the original Tron movie has its fair share of problems. It's a very ambitious goal to visually depict the world our computer programs see in ways non-trained humans can relate to it and to build an interesting story out of it. I would, most certainly, fail in this task.
jedsmith 16y ago
The computer visuals were great. One thing that I caught, being the complete nerd that I am: if you look closely at the terminal that Sam sits down at before going on-grid, there is a copy of top running. It reports the system uptime as a few days (9?) even though that system was supposed to be up for years. Rebooted Tron for a kernel upgrade? The rest was great though, and I smiled too. I wonder if the author knew how his terminal footage was going to be used...Cillian Murphy's actions were entirely plausible in context.

How mistaken I was... Yes, I'm really bitter about producers and artists who don't care to know anything about the history of their art. And they had the presumption to call it 'Tron Legacy'??

You were offended that some people simply had no idea about this?!

It is quite interesting to see how much work has been done.

I've never heard of Houdini so I had to look it up (it's a purely procedural 3D animation package): http://en.wikipedia.org/wiki/Houdini_(software) http://en.wikipedia.org/wiki/Houdini_(software) Here is their demo reel: http://www.youtube.com/watch?v=leJks6ay4tg http://www.youtube.com/watch?v=leJks6ay4tg Apparently Maya, Softimage and 3DS Max are not the only players in this space anymore.

Sorry, small clarification: Houdini is actually descended from the PRISMS package developed by Omnibus Computer Graphics (one of the very first CGI studios (and actually still in business in Japan!)). SideFX (started by two of the original programmers) bought the rights to PRISMS when Omnibus (North America) went under. They opened for business in 1987 and have been going strong since! They have a number of "firsts" to their credit -- for instance, Houdini was the first major 3D package on Linux. Debuted in 1999, although I was beta-testing it before that. For procedural 2D and 3D graphics, there is absolutely nothing like it. However, it's hard for most users to understand, so its popularity has never been great. Anyone doing serious FX work knows all about it, however. (My old boss used to be CTO of Omnibus, in charge of PRISMS development.)

If you're interested in a FOSS application for procedural graphics, take a look at Povray: http://povray.org/ http://povray.org/ It has no (built-in) UI. Its file format is a domain-specific scripting language. :-D

Terminal font looks very similar to BitStream Vera Mono Sans if anyone else was curious.

I didn't like TRON Legacy at all, but after reading this I'm going to watch it again. Several times even.

The story is predictable, but, come on... It's like Star Trek (pre-2009 at least). You know it will probably not live up to your expectations, but you just have to see it anyway. BTW, the original Tron movie has its fair share of problems. It's a very ambitious goal to visually depict the world our computer programs see in ways non-trained humans can relate to it and to build an interesting story out of it. I would, most certainly, fail in this task.

The computer visuals were great. One thing that I caught, being the complete nerd that I am: if you look closely at the terminal that Sam sits down at before going on-grid, there is a copy of top running. It reports the system uptime as a few days (9?) even though that system was supposed to be up for years. Rebooted Tron for a kernel upgrade? The rest was great though, and I smiled too. I wonder if the author knew how his terminal footage was going to be used...Cillian Murphy's actions were entirely plausible in context.
