What an incredibly awesome way to do stop-motion animation!
“We became the first company to take the age-old technique of
replacement animation and combine it with the 21st century technology of
3D printing,” McLean says.
If you’re not familiar with the term “replacement animation,” it is a
technique used in stop motion in which parts of a puppet, usually faces
or limbs, are replaced with similar (but ever so slightly different)
parts to achieve the illusion of movement. McLean’s department is
responsible for creating the replacement faces used during production.
“On
Coraline we produced upwards of 20,000 faces,
ParaNorman was
around 33,000, and with
Boxtrolls we’re upwards of 52,000,” he says.
