RibbonSculpt: Voronoi Ball based 3D Sculpting from Sparse VR Ribbons

DescriptionWe introduce RibbonSculpt, the first method for the interactive surface modeling in VR using sparsely drawn oriented ribbons. Instead of reconstructing a surface from a fully drawn VR sketch, we address the real-time creation and progressive refinement of a closed surface of any topological genus, thanks to the continuous update of a volumetric proxy. The latter corresponds to a filtered subset of the Voronoi balls defined by the user-sketched oriented ribbons. Guided by this proxy, users can easily refine their design by adding or removing ribbons, which sculpt the set of Voronoi balls until the intended 3D shape is achieved. Finally, a mesh is extracted from the proxy surface and further beautified through Laplacian-based energy minimization, yielding a smooth surface that still interpolates the user-drawn ribbons. Our results, supported by user studies, show that RibbonSculpt allows users to model the desired shapes in VR with minimal effort.
