Hi,

I was reading a magazine (computer graphics world) on the issue of
simlulating a human face. The process used was to digitalize a real
face into polygons and manipulate those entities to create facial
expressions. I wonder if anyone out there has tried using boundary
surface representations or NURBS-based surfaces to model a human face
and then changing the expression by varying the curve parameters. A
more crazy thought, if one can use fractals to simulate toplogies and
waves, is it possible to use factal science to describe an entire human 
face?

BTW, this is not my field of research (I am into robotic sensors), but I
am interested in computer graphics. I cannot see any immediate practical 
applications in the above (maybe let plastic surgens preview their 
patient's final outlook, facial animation and making molds of faces like
in Mission Possible). I am just interested if it is conceptually possible 
and whether anyone has explored this idea yet.

Andy
