Some day soon, movies will feature “actors” that are
just software. Countless high-tech companies are working
toward that goal [see “Ready for
Their Close-ups,” in this issue]. One of
them is a little company named Mova on the third floor
of a former can-making factory in San Francisco’s
Dogpatch district.
When Senior Editor Tekla S. Perry, who edited the
article, visited Mova in February, the Mova team put her
into a swivel chair inside a metal cage, facing a bank
of fluorescent tubes and 28 high-resolution digital
cameras. For about an hour, Perry tried not to sneeze,
scratch, or moisten her lips as a production assistant
sponged her face with a cold mixture of phosphorescent
and flesh-toned makeup. After the makeup dried, Perry
was ready for her close‑up. During the exposure, black
lights alternated with standard lights to create two
sets of images—one with her face in normal lighting, one
glowing eerily in the dark.
Mova’s computers took the black-light image, analyzed
the random glowing patterns that had been created when
the rough sponge dabbed on the phosphorescent makeup,
and created a digital mesh representing Perry’s face and
its movements in three dimensions. Were Perry appearing
in a film, animators might change this digital actor
into a space alien, but for now, her image stands as
captured. You can see the video at
