Interesting read, havent seen it posted here.

Voxels seem to be more popular in the news these days. Here's another voxel animation, note how it's achieving a similar state as mentioned in the article.

The technique mentioned in the original post doesn't seem to use voxels at all. Judging from a quick glance at the paper, it seems to calculate the jiggle on a lower-res cage, and then use that to deform the mesh. I didn't find it very realistic though -- there was a very noticeable loss of volume, particularly on the belly.

The article mentioned voxels (volumetric pixels), which is why I posted my link.

Their 3D graphics algorithm attaches the volume pixels ("voxels") of the deformable body to the skeleton. "So when the skeleton moves, the fixed body points also move along the bones and this leads to the passive jiggling movement of the deformable body," Kim says.


I also believe that youtube vid is being rendered in real time, which is why the model is not as accurate -- its a model designed more for video games.

The New Scientist article mentions voxels, but the published paper doesn't:

EDIT: That link is just for the abstract, not the whole paper. You can get the whole paper if you pay or if you're a member of the ACM.

They claim "near real-time". The authors also make several claims about accuracy, realism, and being physically based.

Interesting video on the link. But in reality, it just looked like a wobbly jelly man. Great for Jelly commercials but not much else.

Cinema 4D has a great little 'jiggle deformer' that uses weights. Works a treat, easy to use and great for fat bellies.
