SUMMARY:RibbonSculpt: Voronoi Ball based 3D Sculpting from Sparse VR Ribbo
 ns
DESCRIPTION:Anandhu SURESHKUMAR and Amal Dev PARAKKAT (LTCI-Telecom Paris,
  Institut Polytechnique de Paris, France); Georges-Pierre BONNEAU and Stef
 anie HAHMANN (Univ. Grenoble Alpes, CNRS, INRIA, Grenoble INP, LJK, France
 ); and Marie-Paule CANI (LIX-Ecole Polytechnique/CNRS, Institut Polytechni
 que de Paris, France)\n\nWe introduce RibbonSculpt, the first method for t
 he interactive surface modeling in VR using sparsely drawn oriented ribbon
 s. Instead of reconstructing a surface from a fully drawn VR sketch, we ad
 dress the real-time creation and progressive refinement of a closed surfac
 e of any topological genus, thanks to the continuous update of a volumetri
 c 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 sculp
 t the set of Voronoi balls until the intended 3D shape is achieved. Finall
 y, a mesh is extracted from the proxy surface and further beautified throu
 gh Laplacian-based energy minimization, yielding a smooth surface that sti
 ll interpolates the user-drawn ribbons. Our results, supported by user stu
 dies, show that RibbonSculpt allows users to model the desired shapes in V
 R with minimal effort.\n\nRegistration Category: Full Access, Full Access
