  This paper presents Tabby, an interactive and explorable design tool for 3D
printing textures. Tabby allows texture design with direct manipulation in the
following workflow: 1) select a target surface, 2) sketch and manipulate a
texture with 2D drawings, and then 3) generate 3D printing textures onto an
arbitrary curved surface. To enable efficient texture creation, Tabby leverages
an auto-completion approach which automates the tedious, repetitive process of
applying texture, while allowing flexible customization. Our user evaluation
study with seven participants confirms that Tabby can effectively support the
design exploration of different patterns for both novice and experienced users.
