The facial mesh of various densities are organized into regions activated in certain sets to perform a certain expression. So, standard keywords and parameter sets can activate standard related areas of the mesh to allow use of standardized animations as well as serve as a prime basis for the personalization of the Humanoid that you really want to do. This is not a quick and simple effort. It is very interesting, design-friendly, much simplified authoring, and much more standardizable and demonstratable at all levels of expression using the hanim displacer concept. </p></div><div style="font-family:arial,sans-serif;font-size:12pt;color:rgb(0,0,0)">
