DesigNet: Learning to Draw Vector Graphics as Designers Do
This addresses the problem of integrating AI with professional design workflows for scalable vector graphics, though it is incremental by building on existing methods with specific refinements.
The paper tackles the challenge of AI generating editable vector graphics by introducing DesigNet, a hierarchical Transformer-VAE that incorporates designer tools like continuity control and alignment, achieving competitive results with higher accuracy in continuity and alignment.
AI-driven content generation has made remarkable progress in recent years. However, neural networks and human designers operate in fundamentally different ways, making collaboration between them challenging. We address this gap for Scalable Vector Graphics (SVG) by equipping neural networks with tools commonly used by designers, such as axis alignment and explicit continuity control at command junctions. We introduce DesigNet, a hierarchical Transformer-VAE that operates directly on SVG sequences with a continuous command parameterization. Our main contributions are two differentiable modules: a continuity self-refinement module that predicts $C^0$, $G^1$, and $C^1$ continuity for each curve point and enforces it by modifying Bézier control points, and an alignment self-refinement module with snapping capabilities for horizontal or vertical lines. DesigNet produces editable outlines and achieves competitive results against state-of-the-art methods, with notably higher accuracy in continuity and alignment. These properties ensure the outputs are easier to refine and integrate into professional design workflows. Source Code: https://github.com/TomasGuija/DesigNet.
