Body-shape Transfer for Super Deformation of 3D Character Models

摘要

We present a technique for semi-automatically super-deforming 3D character models. Super deformation is a unique style of exaggeration, often seen in Japanese animation and manga, to enhance characters' cute appearances. Specifically, super-deformed (SD) characters are chubby with stubby limbs and oversized heads. Given a reference SD model with a rig and a target character model, our method automatically calculates a rig of the target model, measures the body shapes, and shortens the target limbs and enlarges the target head by transferring the reference body shape. Our method further makes the target face younger by applying a simple deformation based on a biological insight. We demonstrate that our method can create visually-pleasing SD character models quickly.
