'Chappie': What It Takes To Render a Robot

Nerval's Lobster writes: The visual-effects supervisor on the new film Chappie, Image Engine's Chris Harvey, talked with Dice about what it took to render the titular robot. Director Neil Blomkamp thought Chappie needed to look realistic, like something you might honestly expect to see patrolling the streets a decade or two from now. Image Engine took the concept artwork created by Blomkamp and WETA and rendered it in three dimensions, refining the mechanics so the animated Chappie would move realistically for a six-foot-tall, gun-toting robot. As the movie progresses, Chappie begins to take damage from bullets, flames, and thrown debris; if that wasn't enough, he also ends up covered in graffiti. That sort of wear-and-tear complicated things for the effects team; WETA had to produce three physical Chappie "skeletons" and a multitude of body panels representing the increasing levels of damage, and Image Engine needed to make sure every inch of the digital Chappie was rendered accurately to match. The movie itself might be scoring mediocre reviews, but at least the robot looks good.

    This article feels pretty light on the details. I'd find more details in my "making of Jurassic Park" book I got as a child. All it says is different people work on different stuff and they used physical models to figure out how to model some physics in the digitally version.


    I mean using a stand-in, instead of a tennis ball for actors to interact with? Did Lord of The Rings never happen?

      This isn't a "hey look at this cool story" story. It's a "let's put something from Dice on the front page" story.

  2. great film! by lkcl · · Score: 4, Insightful

    i just went to see it at the cinema, i'm a big fan of sci-fi films, and this one i really liked. if you're an afficionado of sci-fi books and films, there will be nothing new, you should be able to predict everything that happens but i was still absorbed by the novel way the story unfolded. yes it was violent - if you're going to tell a story about out-of-control criminal activity then that's hardly not going to happen - but it was also poignant as well.

    i think the best part about the film was that the robots, because they've been seen before in other stories by the same director (Elysium for example), are not "glorified", they're just "part of the story". the problem with novice sci-fi writers (book or film, especially film because it's a less mature medium for telling sci-fi stories) is that they tend to not really actually have a good background or story (which is why the marvel comics films are so damn good), so as a substitute the director "glorifies" the technology in a wealth of special effects. by complete contrast, the introduction of an entirely new type of consciousness - and its rapid development from child-like behaviour to above-average human intelligence through incredibly painful learning experiences and its desire to remain alive against a ticking clock - that's what really really makes this story so interesting.

    but the best bit i think is how this new being changes the lives of those who initially sought to profit from it (admittedly out of desperation), surprising even themselves by finding that despite their desperation and ganster background they begin to see this robot as a valuable conscious being in its own right.

    so although this film has aspects which have been covered before, i don't know of many films that have done proper justice to the emergence of machine consciousness and the respectf it engenders in those who come into contact with computer-based beings, in the way that this film has managed. it's just a pity that i feel that that message is completely over the heads of the average reviewer.

    Is it just me, or does this movie sound EXACTLY like Short Circuit, but with the "grittified, modernized" feel to it?

      short circuit was designed to appeal to kids, and also featured a robot that, whilst sentient, never went beyond child-like human-level consciousness. the difference here is that this machine consciousness quickly exceeds human-level intelligence whilst at the same time maintaining both an integrity and naivety that is a product of its fast and harsh yet poignant upbringing. in another post i point out that this film has aspects of other films and sci-fi stories that you will definitely have seen before, but please do consider suspending judgement and just enjoy the story as it is :)

    The linked article give it a C. That's quite a bit higher than Kenneth Turan implies in his review: http://www.npr.org/2015/03/06/...

    Don't believe everything you read. If I had mod points I would have upvoted lkcl's earlier post.

    I saw the late night show of Chappie yesterday. I am a science fiction nut (especially hard scifi and cyberpunk - Neal Asher, Peter F Hamilton, Alastair Reynolds, Stephen Baxter, etc.). Chappie is not hard scifi, nor is it grand theatric soap opera. But it paints a vision of how robots and AI would eventually get integrated into society. And I *loved* the movie for it. If you see District 9 (the director's earlier work), you will see that Neill Blomkamp has a very distinct and unique viewpoint. He focused not on technology, not on robotics and special effects, but on how all this will eventually coexist in our super fu*ked up world.

    And the irony is thick in the movie. You have a bunch of outlaws - violent thugs - that first ridicule the robot/AI and try to take advantage of it, but eventually respect the being for what it is - an independent consciousness. Chappie eventually becomes part of the family. And I agree with the director's vision. The urban backdrop of modern day South Africa / JoBurg - it personifies a certain grittiness and bizarreness that just works perfectly for the story.

    Sure, the movie and story has huge shortcomings. But for me, the main storyline, unique viewpoint, and the way it is directed - it all adds up to make a superb movie.

    It is also worth reading Neal Asher for an even more violent and futuristic version of what this movie essentially is.
