Abstract: The invention relates to a method of generating at least one synthesized image of at least a portion of a head of hair in movement, the method comprising the steps consisting in calculating a shape of at least one director hair by applying to the at least one director hair at least one mechanical model of an inextensible rod having inertia and stiffnesses in twisting and in bending, and in generating at least one virtual image of the at least one portion of the head of hair from the shape of the director hair.

Abstract: The invention relates to a method of generating a synthesized image of a hair, comprising the following steps: calculating the shape of the hair by applying a behavioral relationship determining the shape of the hair as a function of a physical parameter linked to a mechanical property of the hair, in particular the linear density; producing an image of the hair of shape that has been calculated in this way.

The behavioral relationship may be given by the minimization of the following function: E = K L ? ? 0 1 ? [ 1 2 ? ( k ~ ? ( s ~ ) - ? ) 2 + 1 ? ? z ~ ? ( s ~ ) ] ? ? s ~ , where ?=Lk0 and ?=K/g?L3, and where L designates the length of the hair, k0 its spontaneous curvature, K its bending moment, ? its linear density and g the acceleration due to gravity, {tilde over (s)} the curvilinear abscissa relative to the length of the hair, {tilde over (k)} its local curvature relative to its length and {tilde over (z)} its height relative to its length.
