SMLib™ SMLib™
Our flagship product built upon TSNLib™ provides fully functional non-manifold topological structure and solid modeling functionality including the ability to perform NURBS boolean operations, fillets, etc. TSNLib™ TSNLib™
Built on top of GSNLib supporting trimmed surface representations. GSNLib™ GSNLib™
A basic curve and surface NURBS library. GSNLib™ provides a useful interface to NLib while adding value as well. Includes curve/curve and surface/surface intersection and polygon modeling. NLib™ NLib™
A comprehensive BSpline NURBs library fully supporting curves, surfaces, and volumes with an extensive set of shape query and construction tools. VSLib™ 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. SDLib™ SDLib™
Subdivision surface source code library that creates and modifies complex shapes with hierarchical Catmull-Clark surfaces. PolyMLib™ PolyMLib™
Polygonal based geometric modeling to repair, optimize, review and edit triangle mesh models. Analyze surface properties, repair and optimize surface meshes. Data Translators Data Translators
NURBS based geometry translators to interface between Nlib™, GSNLib™, TSNLib™, SMLib™ and IGES, STEP, SAT, VDAFS, OpenNURBS, and Parasolid XT. |

| Solid Modeling Solutions Announces GSNlib |
|
| Advanced NURBS geometry with surface/surface intersection |
|
BELLEVUE, WA - April 30, 2002 - Solid Modeling Solutions is pleased to announce the availability of GSNLib, the NURBS geometry library written in C++ combined with full point/curve/surface intersection functionality. SMS will continue to offer the C version of NLib, and GSNLib is 100% compatible with NLib and SMLib in data formats and computation. GSNLib contains an object-oriented version of NLib, with class libraries contructed for each of the contains an object-oriented version of NLib, with class libraries contructed for each of the extensive number of functional areas. These classes support a wide variety of query and analysis methods. |
| The most commonly used methods in GSNLib include: |
|
- Evaluation - curve/surface - points, derivatives, geometric properties
- Intersection - point/curve, curve/curve, point/surface, curve/surface, surface/surface, curve and surface self-intersection.
- Minimization/Maximization/Normalization (and many other measurements) - point/curve/surface to point/curve/surface.
- Offsetting - single curve, composite curve with trimming, procedural for surface.
- Dropping/Lifting Curves - 3D curve into surface parameter space and surface parameter space up to 3D.
- Analysis - inflection points, curve length, surface area, minimum and maximum derivatives, silhouette points.

In addition to the native functionality, GSNLib provides an Object-Oriented Extensibility Framework that should allow developers to extend both the geometric coverage and numerical algorithms. GSNLib is designed to be sufficiently robust for demanding geometric modeling applications, efficient enough for performing intensive graphics applications, and easy to use from a programming point of view.
GSNLib is positioned in functionality between the NURBS-based geometry kernel NLib and the full-featured non-manifold topology kernel SMLib. All three libraries are provided by the same technical development and support staff to assure 100% compatibility and consistent support levels.
Data exchange software is available for IGES, STEP, VDAFS, and SAT. More details can be found on the SMS website at www.smlib.com, by contacting Robert Blomgren, VP of R&D, Solid Modeling Solutions, at (206) 463-1417, or send an email to sales@smlib.com. |
