Virtual Stuntmen Ready for Hollywood
Kerhop writes "Discovery Channel has an article about a new form of virtual actors in movies. In particular "Endorphin's virtual actors learn how to move and react independently, unlike most computerized characters now that depend on fixed databases containing animated clips". MSNBC also is featuring a news video (no direct link is available, stream must to be added to playlist). The featured software Endorphin is created by Natural Motion."
Now we get to hear the people in Hollywood complain about having their jobs outsourced to computers.
Virtual porn stars!!!
Dated: June 26, 2003
and from the article "...will make their debut next year in the film "Troy,"..."
Frist psot?
^_^
I started reading the Discovery Channel article and saw they'd make their debut "next year in the film 'Troy.'" And I thought, hey, they just made a movie about Troy, they're going to make another one? Then I saw the June 26, 2003 date of the article. Slow news day I guess.
"This? I can make a hat, I can make a brooch, I can make a pterodactyl..."
I assumed many "stunts" were done my CG!
How about the burning Terminator emerging from
the fire in Terminator 2?
...to reproduce the robotic movements of the virtual Stallone and Bronson.
Forget movies...this would/could revolutionize gaming. Could you imagine actual thinking/reacting NPC characters that are not just set to a script. And if literally you can get fluid muscle movements... the graphics could be amazing. Okay, I'm done fantasizing. Regardless of how many times I see new "Revolutionary" technology it never seizes to amaze me.

The world's first virtual stuntmen, born out of an Oxford University zoologist's research into human motion, will make their debut next year in the film "Troy," according to a press release issued this week by the university.
I thought this site was supposed to be News for nerds. This story is over a year old.

There are advantages to doing your own stunts. At least today the virtual actors are shown only from a distance, since facial features still don't quite look real enough (though even before Troy there were some lovely examples in Lord of the Rings. Those were keyframed rather than virtual actors.)
Being able to focus up-close on an actor doing a stunt gives a verisimilitude that the audience really appreciates; they believe that the character is in danger. But they can also detect the jump-cuts that usually surround a stunt (since a stunt is shot on its own, with lots of preparation beforehand, and the camera is immediately stopped so that everybody can be checked out.)
So when they're ready to seamlessly slip a virtual actor into the frame, then back to the human actor at the end, and make it look like a single shot, you'll really be thrilled. You will believe Brad Pitt can kick ass. (I once played Achilles myself and I loved Brad Pitt's work.)
... he'll come on at the start of every movie, and tell the kids to quit downloading his code!
Did Buzz Lightyear do his own stunts, or did he have a stunt double?

Apple is rumored to be developing a portable MP3 player that has a hard drive, leaked sorces say it's name will be the 'I-Pod'
Outsourced actors......well, the next logical step would be to somehow figure out a way to force them to belong to the screen actors guild (union), before the are allowed to "act"

What relation does this technology have to the Weta Digital's Massive program, which was used to create the characters for the war scenes in the Lord of the Rings movies? That program used sub-elements called Agents which could be tailored to give you certain randomated AI actions for characters. (Check the LOTR DVDs or google for Weta Massive for more info... I don't want to slashdot anyone in particular ;-) )
Wow... imagine a whole bunch of these taught to do Beowulf...
There are two main approaches to this - the "animation splicing" systems, where canned bits of motion are spliced together by a program, and the "behavior" systems, where control programs are trying to optimize some goal. The first major appearance of a good "splicing" system was the baby 'zillas in Godzilla 2000. That's what most feature films are using today.
Kinematic motion generation has been around for years, and that's what you see in games. It doesn't look real, but it works well enough for gameplay. The physics isn't realistic. That's why, from across the room, EA Football looks different from NFL football. Those jerky motions really pop out at you, especially when they're alternated with nice motion-captured moves.
Endorphin isn't as automated as it looks; much manual tweaking of the motion is necessary. Motion Factory has more automation, but it's kinematic. Automatic physically-realistic animation is hard, because you have to solve the robotic control problem. The animation community may yet do this. But they're not there yet.
(I've done some work on this.)
Isn't it people who download movies that put people like stuntmen out of jobs?
Although the article may be a year old, this news was only aired on the Discovery Channel this week.
...virtual Darwin Award.
Table-ized A.I.
Within 10 years, someone will make a full-length, CGI feature film that's indistinguishable from "live, shot on film."
It may not be cost effective, but the cat will be out of the bag.
The actor's guilds will moan and groan. Actor's "trademark voices and mannerisms" will become protected intellectual property, with exemptions for spoofs and other "fair use." There will be court fights for awhile.
You won't see many new film actors after that point.
Porn will be among the early adopters go "all digital" for hygenic, financial, and other reasons. We'll have a lot of unemployed former porn stars.
On the plus side, the division between movies and games will blur. As someone else already hinted, games of the future will look "live" rather than animated. Sports games will "star" real NBA players that look as real as they do on TV. Movie-based games will "star" the same characters as in the movies, and will look just as real.
One potential downside to this technology that must, and will, be worked around:
Videotapes of crimes will become suspect. Unless you can prove beyond a reasonable doubt that the tape was NOT created in a computer, it will be inadmissable in court. You'll see security cameras equipped with "electronic seals" that stand up in court. These seals will say "this is what the camera saw and this is when it saw it."
Knowledge is how to play a game, intelligence is how to win, wisdom is knowing what game to play.
The article may be old news, but fully reactive software stunt men have been around since 2002. I did hours of "research" on this topic with some really good software.
Clearly the next step is to make the audience virtual. You send your movie-watching robot to watch the movie for you, and it e-mails you a "thumbs-up" or "thumbs-down", freeing you to read a book or take a walk. Perhaps this is progress after all.
Soylent Green is peoplicious!
Which isn't much different from directing a Seagal film.
Mercy was given to me by Christ...I must give the same to others.
Or I should say we just had a demo. I work for a Digital Post Production house and we also use Massive for crowd simulation. Endorphin is an interesting technology which I believe demos very well but practical use may prove to be a bit harder.
The basic concept is intersting. Actors are "trained" using a neural network setup. The actions are not captured or keyframed, they are "learned" based on a fuzzy set of rules that allow the actor to adapt to its environment. These behaviors can then be combined to create a complete motion. For instance, in one of the demos you can have one actor tackle another. This is something you could easily motion capture, but the interesting bit happens when you change the direction of the tackle. The actor adapts and falls in a new way because the "tackle" is a behavior. The combination of dynamics and adaptive motion allow you to make changes without having to build lots of new in-betweens or blend shapes. It also allows you to set target poses, not target positions. For instance, in that tackle, if you want the actor to end in a Hesiman pose and then change the animation to a different position, the actor will finish in that pose in the new end position, not snap back to where you set the pose.
Unfortunately, this also has some big drawbacks. These behaviors that are taught to the nueral nets can only be built but the software's creator. You cannot create your own behaviors. I'm sure this type of thing will be opened up in the future, but for now you are stuck with some canned behaviors. Again, makes for great demos but I can easily see hitting the wall with that limitation in production.
Secondly, it only works on bipeds, or more specifically, their biped. Motion re-targeting will allow you to remap the motion to non-human bipeds, but you are still limited to bipeds with human like bio-mechanics.
I also wonder about low level noodle-ability. In animation production, it doesn't matter if it is physically correct, it matters if it looks good and the director is happy. That usually has very little to do with reality (i.e. how interesting would the Matrix have been if people moved in real-world way instead of an interestingly choreographed ballet-fight?) I wonder how adaptable such a sytem is.
This product has a different market than Massive. Massive includes a more simplified fuzzy brain system that allows your motion captured creatures to adapt to their environments or even interact with dynamics. Endorphin is more about syntesizing motion from neural net behaviors. (That is a gross simplification, but hopefully gives some context.)
I like the idea of where this is going, but I think it has to mature a bit more before it is really useful to us.
... the computers will be complaining about having their work outsourced to cheaper systems abroad.

I almost misread that as "Virtual Statemen Ready for Hollywood," which made me think "don't they have those in congress already?"
A hack is just an idiom waiting for wider use.
I believe that I have seen this before, in both the "Truck Dismount" (Rekkaturvat) and "Stair Dismount" (Porrasturvat) versions. They are available for download.
My favorite was trying to get the truck to throw the guy *completely* over the wall, or go for bonus points getting the guy's head to rattle back and forth between the wall and the truck grill.
Great for getting stress out on a boss (at the time) whom we imagined we were putting on the truck, etc.
