1. Introduction

a novel muscle activation model that offers more flexibility than standard fiber-based models
a physics-based simulation method that retains realism even with significant external forces or substantial modifications of the face geometry and tissue material properties
an inverse modeling optimization to adapt the simulation template to a series of expression scans of a specific person.

FLAME is described by a function:

— coefficients describing shape
— coefficients describing pose
— coefficients describing expression
— template mesh in the “zero pose”
— “zero pose”
— shape blendshape function to account for identity related shape variation
— corrective pose blendshapes to correct pose deformations that cannot be explained solely by LBS
— expression blendshapes that capture facial expressions
— A standard skinning function is applied to rotate the vertices of around joints , linearly smoothed by blendweights
