High Quality Content by WIKIPEDIA articles! Solid Modeling Solutions is a company who has an implementation of a mathematical representation of NURBS (Non-uniform rational B-spline), 3D geometry, and Solid modeling technology which emerged in the 1980`s and 1990`s into a commercial implementation known as SMLib (for solid modeling library). This article will provide the background and history of this implementation into a commercial product line from Solid Modeling Solutions™ (SMS). SMS is an independent supplier of source code for a powerful suite of 3D geometry kernels. SMS provides advanced NURBS-based geometry libraries, SMLib™, TSNLib™, GSNLib™, NLib™, SDLib™, VSLib™, and PolyMLib™, that encompass extensive definition and manipulation of NURBS curves and surfaces with the latest fully functional non-manifold topology.
