DrawingSpinUp: 3D Animation from Single Character Drawings
Jie Zhou, Chufeng Xiao, Miu-Ling Lam, and Hongbo Fu

TL;DR
DrawingSpinUp enables the creation of realistic 3D animations from single character drawings by addressing contour ambiguity and delicate structures, outperforming existing methods in quality and realism.
Contribution
The paper introduces a novel system that reconstructs and animates 3D characters from single drawings, using contour removal/restoration and skeleton-based thinning for improved accuracy.
Findings
Outperforms existing 2D and 3D animation methods
Produces high-quality, plausible 3D animations from a single drawing
Validated by experimental evaluations and user studies
Abstract
Animating various character drawings is an engaging visual content creation task. Given a single character drawing, existing animation methods are limited to flat 2D motions and thus lack 3D effects. An alternative solution is to reconstruct a 3D model from a character drawing as a proxy and then retarget 3D motion data onto it. However, the existing image-to-3D methods could not work well for amateur character drawings in terms of appearance and geometry. We observe the contour lines, commonly existing in character drawings, would introduce significant ambiguity in texture synthesis due to their view-dependence. Additionally, thin regions represented by single-line contours are difficult to reconstruct (e.g., slim limbs of a stick figure) due to their delicate structures. To address these issues, we propose a novel system, DrawingSpinUp, to produce plausible 3D animations and breathe…
