A few months ago I started researching motion capture so I could build a full 3d model of my sona and animate him with easier natural movements, that failed horrificly xD
But check out this, it's almost precisely what I needed and if it's indiegogo get's funding what I originally hoped for would become a possibility for the future! Live face tracking with HQ models! Sure we have this with some webcams already but Ive nevver seen in it as clean and smooth as this in all the programs I've tried.
