(AP) — Subjects like rapid prototyping, 3-D texture painting and the intricacies of digital media review systems became comic material Saturday for Olivia Munn and Jason Segel, hosts of the film academy's Scientific and Technical Awards. Representing the "science" part of the Academy of Motion Picture Arts and Sciences, the work of the 11 groups recognized during the untelevised dinner celebration at the Beverly Wilshire hotel is highly specialized — mostly tools for viewing, sharing and manipulating digital media — but it has contributed to countless hit films. — "The Avengers": The Marvel superhero smash is one of many action films to make use of the Aircover Inflatables Airwall, a giant, inflatable panel that becomes an instant green-screen for special effects. — "Anomalisa": This stop-motion film, nominated for best animated feature Oscar, makes use of Laika's rapid prototyping techniques, which use 3-D printers with color-uniform results to create interchangeable faces and expressions for the puppets used in stop-motion animation.
