SUMMARY:BoolSurf : Boolean Operations on Surfaces
DESCRIPTION:Technical Papers\n\nBoolSurf : Boolean Operations on Surfaces\
 n\nRiso, Nazzaro, Puppo, Jacobson, Zhou...\n\nWe port Boolean set operatio
 ns between 2D shapes to surfaces of any genus,  with any number of open bo
 undaries. We combine shapes bounded by sets of freely intersecting loops, 
 consisting of geodesic lines and cubic B\'ezier splines lying on a surface
 . We compute the arrangement of shapes directly on the surface and assign 
 integer labels to the cells of such arrangement. \nDifferently from the Eu
 clidean case, some arrangements on a manifold may be undecidable. We detec
 t undecidable arrangements and help the user to resolve them. Also, we ext
 end to the manifold setting recent work on Boundary-Sampled Halfspaces, th
 us supporting operations more general than standard Booleans, which are we
 ll defined on undecidable arrangements, too. \nOur implementation discreti
 zes the input shapes into polylines at an arbitrary resolution, independen
 t of the level of resolution of the underlying mesh. We resolve the arrang
 ement inside each triangle of the mesh independently and combine the resul
 ts to reconstruct both the boundaries and the interior of each cell in the
  arrangement. We reconstruct the control points of curves bounding cells, 
 in order to free the result from discretization and provide an output in v
 ector format. We support interactive usage, editing shapes consisting of u
 p to 100k line segments on meshes up to 1M triangles.\n\nRegistration Cate
