Our Products

SMLib™, TSNLib™ and NLib™ are a graduated set of 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 SDLib™ for subdivision surface modeling and PolyMLib™ for polygonal modeling. Conversion between geometric representations is also possible.


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.


A trimmed surface library built on top of NLib™ with non-manifold topology structures. In addition to NURBS, TSNLib™ includes polygonal modeling definitions and operations.


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.


Subdivision surface library that creates and modifies smooth and complex shapes with hierarchical Catmull-Clark surfaces.


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™, TSNLib™, SMLib™ and common data formats such as IGES, STEP, SAT, VDAFS, OpenNURBS, and Parasolid XT.
