Localized-hierarchy surface splines (LeSS)
Proceedings of the 1999 symposium on Interactive 3D graphics - SI3D '99
An explicit spline representation of smooth free-form surfaces is combined with a hierarchy of meshes to form the basis of an interactive sculpting environment. The environment offers localized hierarchical modeling at different levels of detail, direct surface manipulation, change of connectivity for extrusion and to form holes and bridges, and built-in tangent continuity across the surface where wanted. The free-form surface is represented and can be exported either in NURBS form or as cubicdoi:10.1145/300523.300524 dblp:conf/si3d/Gonzalez-OchoaP99 fatcat:gg4b4x3d6nf5nfxwopsjy5jhka
