ViewCraft3D: High-Fidelity and View-Consistent 3D Vector Graphics Synthesis

Chuang Wang

Abstract:

3D vector graphics play a crucial role in various applications including 3D shape
retrieval, conceptual design, and virtual reality interactions due to their ability
to capture essential structural information with minimal representation. While
recent approaches have shown promise in generating 3D vector graphics, they often
suffer from lengthy processing times and struggle to maintain view consistency. To
address these limitations, we propose ViewCraft3D (VC3D), an efficient method
that leverages 3D priors to generate 3D vector graphics. Specifically, our approach
begins with 3D object analysis, employs a geometric extraction algorithm to
fit 3D vector graphics to the underlying structure, and applies view-consistent
refinement process to enhance visual quality. Our comprehensive experiments
demonstrate that VC3D outperforms previous methods in both qualitative and
quantitative evaluations, while significantly reducing computational overhead.
The resulting 3D sketches maintain view consistency and effectively capture the
essential characteristics of the original objects.
