Interactive Viewpoint Exploration for Constructing View-Dependent Models

We introduce an interactive method to sequentially find viewpoints for constructing view-dependent models which represent view-specific deformations in classic 2D cartoons [Chaudhuri et al. 2004, 2007; Koyama and Igarashi 2013; Rademacher 1999]. As users design one view-specific model from a single-fixed viewpoint, the system searches successive viewpoints for subsequent modeling and instantly jumps to the next viewpoints. Thereby, the users can efficiently repeat the design process of view-specific deformations until they are satisfied. This method is simple enough to easily implement in an existing modeling system. We conduct a user study with novice and amateur users and confirm that the proposed system is effective for designing view-specific models envisioned by the users.
