NURBS ([[Non-uniform rational B-spline]]), 3D geometry, and [[Solid modeling]] technology 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 [http://www.smlib.com 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.

VSLib™ provides deformable modeling as part of a library using the constrained optimization techniques of the calculus of variations. The library supports several very different geometric operations.

== Philosophy ==

SMS provides source code to customers in order to enhance and enable their understanding of the underlying technology, provide opportunities for collaboration, improve time to repair, and protect their investment. Web-based delivery of product delivery, maintenance, and communication has enabled SMS to respond to customer needs. The pricing philosophy provides a stable base of technical expertise, and is very cost-effective for its customers, when viewed fromreduces the perspective of total cost of ownership of complex software. A license for an SMS product represents a fraction of what it would cost to develop and maintain the same capability in-house.

For reviews of geometry kernels shortly after the first release of SMLib, see Joe Greco's article "Kernel Wars - Episode 1"<ref>"Kernel Wars - Episode 1", Joe Greco, CADENCE magazine, November 1999</ref> and Don LaCourse's article on Geometric Modeling Kernels Revisited".<ref>"Geometric Modeling Kernels Revisited", Don LaCourse, Cadalyst magazine, April 2001</ref> Also, see a recent review of PolyMLib in Desktop Engineering, Nov 2008. <ref>"Polygonal Mesh Library for Postprocessing 3D Scan Data", Desktop Engineering, Nov 2008</ref>
