SMLib, TSNLib, GSNLib, and NLib are a graduated set of source code libraries supporting NURBS geometric modeling. Together these libraries empower the user to define, create, evaluate, and modify 3D, geometric models represented as NURBS curves, surfaces, trimmed surfaces, or solids. Equally powerful is the native, non-manifold topology definition that makes intersections and boolean operations possible. SMS also offers VSLib for deformable modeling, SDLib for subdivision surface modeling, and PolyMLib for polygonal modeling. Conversion between geometric representations is also possible.
SMLib - Our flagship product built upon TSNLib provides solid modeling functionality with fully functional non-manifold topological structures including the ability to perform NURBS boolean operations, fillets, shell offsets, etc.
TSNLib - A trimmed surface library built on top of GSNLib with non-manifold topology structures. In addition to NURBS, TSNLib includes polygonal modeling definitions and operations.
GSNLib - A basic curve and surface NURBS library. GSNLib provides a useful, C++ interface to NLib while adding value such as curve/curve, curve/surface, and surface/surface intersection.
NLib - A comprehensive BSpline NURBS library including curve and surface definition, creation, evaluation, and modification. NLib offers many advanced surface construction options such as sweeping, skinning, least squares fitting, etc.
VSLib - A deformable modeling library using the constrained optimization techniques of the calculus of variations. VSLib contains advanced tools such as creating an N-sided surface patch.
SDLib - Subdivision surface library that creates and modifies smooth and complex shapes with hierarchical Catmull-Clark surfaces.
PolyMLib - A polygon-based geometric modeler with tools to repair, optimize, analyze, and edit triangle mesh models. Besides fixing meshes to fill holes and remove disproportionate triangles, PolyMLib includes smoothing, shape editing, deformation, decimation, and remeshing.
Data Translators - Our NURBS based geometry translators interface between Nlib, GSNLib, TSNLib, SMLib and common data formats such as IGES, STEP, SAT, VDAFS, OpenNURBS, and Parasolid XT.
