"When it comes to replicating human poses and natural movement, artists often look to anatomical models. Traditional figures do have their limitations, though, with the lack of details making it difficult to recreate the lines of a raised shoulder or a classed first. But things are set to change, with a new figure on the market called the S.F.B.T-3, (Special Full-action Body Type v.3). Ten years in the making, this figure has 80 moveable parts in it’s body, allowing for an unprecedented number of poses and anatomical designs.” SOURCE: http://en.rocketnews24.com/2013/10/07/meet-the-artists-model-set-to-improve-accuracy-for-anime-character-illustrators/
