There was a company in incubation called Genemation. It strove to achieve something similar with PCA models of faces. It is generally possible, given consistent markup (which GMDS can find and optimise over automatically), to construct reasonably realistic models with modes that each respects and represents an observed expression. The commercial value of such an application was never entirely clear and some models were shown where PCA also sampled the texture (as in AAM) to make ethnic modes of variation of even gender-related model modes. For film studios this whole process can save a lot of work (rendering upon changes to modes) and this was one of the target markets for Genemation, along with game makers. Disney works on something similar these days [32].
