This video is a sample of many of the amazing new CG technologies developed over the past year, featured at SIGGRAPH 2013. The video shows things like flowing water, cloth, bouncing blobs, realistic hair, and on-the-fly generation. Previous years' videos inside!

From one of my favorite papers from the 2012 video is the probabilistic model for component-based shape synthesis, taking components to design new items.

Ugh. Few things in the world make me feel bad about myself. SIGGRAPH is one of them. I'll go back to banging rocks together while you these people go about their business of reverse-engineering reality.

If you can do it, you must watch it at 1080p. Especially the snowballs look outstanding. (I can believe that this is a really tough problem, and they've solved it wonderfully.)
This kind of stuff has an interesting real world consequence: we are soon to reach the point, if we haven't already, where photographs and even movies cannot be trusted to be accurate representations of reality. What does this do to the court system?

Chocolate Pickle, I believe with court presented material the trust follows the expert witness who presents it.

Good Lord, the torn and crumpled paper. That's just showing off.

I feel confident that we're all living in a simulation that is being demonstrated at SIGGRAPH 2030.

I want that garment editing software from the 2011 video SO BAD, is anything like that commercially available?

Chocolate Pickle: Someday, a TPM chip will be embedded into your camera. Every photo you take will be signed by this chip, attesting to the authenticity of the photo. Manipulations (cropping, color balance, etc) will have to take place on trusted systems that add their signatures to an unforgeable digital chain of custody. Anything without a valid chain of custody will be inadmissible in court.
This technology already exists. High end cameras already have TPMs (which are very cheap). It effectively solves the tampering problem by raising the cost (now you need somebody who can hack a TPM --- very, very hard), but introduces all kinds of other social and technical problems.

Buried in the middle there was a reference to a non-graphics technology: using an air pump to provide tactile feedback. It's a cool idea but the lag is going to be a problem.

In SIGGRAPH 2020 they reduce the viscosity of air.

Siggraph 2012 had a lot of similar haptic feedback devices. They sounded neat but weren't that impressive to use.

me too! Here's the research lab's page, but I don't know how to get the actual software

Some very interesting stuff here! Thanks for the video. The snow balls and paper ripping are especially cool.

Not necessarily, at least not for the bouncing balls game they showed. You can send a puff of air out in the correct direction whenever a ball's headed that way, and if the person misses the ball, they won't feel the puff. Since the air puff is a one-way transmission of information, you don't have to worry about latency - you can compensate for that as long as you know roughly how far away the target is.

Well that's really great, but I'm going to get back to this bug report about a data entry form

I'm not sure if the femtophotography is CGI exactly, but its really cool. They take massive numbers of really fast really low exposure photographs of a huge number of light bursts and then stich them together into a movie that shows light moving in slow motion.
Here is a talk on the subject, and more examples of it

Here are two more papers with pretty videos that didn't make the preview this year, both focusing on real-time applications:
Position-Based Fluids makes particle-based fluids faster and friendlier to interactive applications by enforcing incompressibility in a way that doesn't lead to explosions when you turn the time step up too high.
Near-Exhaustive Precomputation of Secondary Cloth Effects achieves high-quality real-time cloth animation by (as the title suggests) computing in advance nearly everything the cloth could possibly do in response to character animations assembled from a fixed library of animation clips.
Full disclosure: my advisor was on the latter.
showbiz_liz, there's another garment editing paper this year, which looks like it substantially builds off the 2011 paper (and involves some of the same people).
Blasdelb, computational photography is definitely fair game for SIGGRAPH, perhaps even more so when it tells you something about light transport.

My brain, it's melting.
Hurries off and sees if one can parameterize surface-convoluted protein/fat gel-ellipsoids as a sparse mesh fluid dynamical vector space wibble wobble eigenfunction with ONLY A SPINAL CORD

@showbiz_liz: Here's something similar, commercially available right now. Expensive though.

@ChocolatePickle: Fortunately for all of us, SIGGRAPH is not wholly on the fake side of the real vs fake photo/video arms race. Research like this will detect manipulations of pictures better than software like this (or the newer stuff) can fake it.

Ditto. It's been over 10 years since i went, but it was always a blast seeing some of this stuff up close. Not to mention seeing a good length of the first Toy Story over a year before it hit theaters, i didn't envy the ones that got shown after that one. ;)

Only two grand for the most expensive one? Man, times have changed. I remember Maya v1 being mid five figures. I even paid for Softimage back in the day, and i WISH it was only two grand. ;) Not to mention my poor SGI O2 hasn't been turned on in years. ;)

It's all great, but will it make future characters in children's animated movies less squinty? They all seem to be suffering from an eye defect right now.

I always get excited at SIGGRAPH time. Also, I'm giving a talk about breaking into the industry. Bonus points if you come by and say hi from my favorite internet community :)
