Approach
Although FaceGen generates conventional 3D mesh data, it uses a "parameterized" approach to defining the properties that make up a face, and by using a fixed set of parameters it is able to morph and modify a face model independently of output resolution. FaceGen 3.3 allows the user to randomize, tween, normalize and exaggerate faces, and also includes algorithms for adjusting apparent age, ethnicity and gender. It also allows limited parametric control of facial expressions, and includes a set of phoneme expressions for the animation of characters with "speaking" roles.
FaceGen can also generate 3D models from front and side images of a face, or by analyzing a single photograph.

Famous quotes containing the word approach:
“Oh! mystery of man, from what a depth
Proceed thy honours. I am lost, but see
In simple childhood something of the base
On which thy greatness stands; but this I feel,
That from thyself it comes, that thou must give,
Else never canst receive. The days gone by
Return upon me almost from the dawn
Of life: the hiding-places of man’s power
Open; I would approach them, but they close.”
—William Wordsworth (1770–1850)
“The modern world needs people with a complex identity who are intellectually autonomous and prepared to cope with uncertainty; who are able to tolerate ambiguity and not be driven by fear into a rigid, single-solution approach to problems, who are rational, foresightful and who look for facts; who can draw inferences and can control their behavior in the light of foreseen consequences, who are altruistic and enjoy doing for others, and who understand social forces and trends.”
—Robert Havighurst (20th century)
“... the ordinary is simply the universal observed from the surface, that the direct approach to reality is not without, but within. Touch life anywhere ... and you will touch universality wherever you touch the earth.”
—Ellen Glasgow (1873–1945)
