Blendshapes (linear shape interpolation models) are perhaps the most commonly employed technique in facial animation practice. A major problem in creating blendshape animation is that of blendshape interference: the adjustment of a single blendshape "slider" may degrade the effects obtained with previous slider movements, because the blendshapes have overlapping, non-orthogonal effects. Because models used in commercial practice may have 100 or more individual blendshapes, the interference… CONTINUE READING
