Computer method and apparatus for rotating 2D cartoons using 2.5D cartoon models

摘要

Disclosed herein are methods, apparatus, and computer program programs that use 2D drawings of a cartoon in different views to automatically construct rotated views of the subject cartoon. Embodiments involve a novel structure, the 2.5D cartoon model, which can generate plausible renderings of the cartoon in any view. Two or more input drawings can be leveraged to construct a 2.5D cartoon model that supports full 3D rotation. Unlike a 3D model, however, renderings produced by a 2.5D cartoon model retain the 2D nature and hand-drawn appearance of the input drawings, and support a wide range of 2D stylizations and shapes that would be impossible with a 3D model.
