which will be launched this week. It currently has 250 stars. The feature of this project is to make "paper people" move.

Effect
Introduction
which, due to their perspective-dependent properties, introduce significant ambiguity during texture synthesis. Moreover, due to their fine structures, small regions represented by single-line contours (such as the thin limbs of a "paper-thin" person) are also difficult to reconstruct.
DrawingSpinUp, which can generate realistic 3D animations, bringing character drawings to life by not only allowing them to rotate but also jump and even perform breakdancing. To enhance the visual quality of characters, DrawingSpinUp adopts a "remove-first, then-recover" strategy. This involves first removing perspective-dependent contour lines, followed by re-rendering them after the re-oriented and reconstructed character is ready. For improving geometric forms, DrawingSpinUp developed a skeleton-based refinement deformation algorithm that optimizes thin structures represented by single-line contours. Experimental evaluations show that DrawingSpinUp outperforms existing 2D and 3D animation methods, capable of generating high-quality 3D animations from a single character drawing.
Technical Architecture
The technical process of DrawingSpinUp is as follows:
the input drawing is processed for contour area removal and restoration. a rough 3D geometric model is generated, followed by fine-tuning of its shape and texture. : A two-stage geometry-aware stylization network is proposed, which recovers the original drawing style (including texture details and contour lines) in each frame of animation.
Comparison
it can generate more visually satisfactory character animation results after being given input drawings and target motions.
