It does seem like this technology is either old or just a decade or two too late. Aren't there ways nowadays of generating 3D models from 2D sketches that would serve better for this kind of intuitive topology animation?
- _yosefk 11y agoIf you know about such ways, please do tell, it'd be great... I haven't heard about anything along these lines that is actually used in professional work.
- arketyp 11y agoWhat about [1] for example. I'm also thinking about the growing trend of technologies related to auto calibration such as Microsoft's Photosynth. It seems pretty certain to me that 3D modeling is the future of animation. [1] https://www.youtube.com/watch?v=tbUljHJv4Rg https://www.youtube.com/watch?v=tbUljHJv4Rg
- _yosefk 11y ago[1] is pretty cool! I don't think it's quite production-ready; first of all it's simply very new (2014), and then the 3D models seem to me to need manual polishing, and most importantly, this demo doesn't mention animation, which I guess would require the same rigging and then control manipulation as you'd do with hand-modeled 3D, and you'd run into the same limitations as with normal 3D rigs (with some things "breaking the rig".) I wager that the 2D approach in TFA has a different set of limitations and these will be preferable to some. Still, cool stuff! I wondered when something like this will show up.
- dahart 11y agoMost of the examples they used in the video are topology changes in 2d that results from motion without topology changes in 3d, so you have a good point. But animation of topology changes is not a subject that has been well researched yet, in 3d or 2d, so if you're interested, it might be worth looking into exactly what is new here and why its coming out now. In case you don't know about SIGGRAPH, it has historically been the best showcase of breaking graphics research and techniques. That doesn't guarantee something is new or good, but its one of the best first-order approximations there is, so, even when a SIGGRAPH paper looks simplistic or old-hat to me at first, I will generally give it the benefit of the doubt, because multiple experts in the field have reviewed it and found it worthy, so chances are I'm overlooking something.
