Geometric modeling kernel

A geometric modeling kernel is a solid modeling software component used in computer-aided design (CAD) packages. Available modelling kernels include:

• ACIS is developed and licensed by Spatial Corporation of Dassault Systèmes.
• SMLib is developed by Solid Modeling Solutions.
• Convergence Geometric Modeler is developed by Dassault Systèmes.
• Parasolid is developed and licensed by Siemens.
• Romulus was a predecessor to Parasolid.
• ShapeManager is developed by Autodesk and was forked from ACIS in 2001.
• Granite is developed by Parametric Technology Corporation.
• C3D Modeler is developed by C3D Labs, part of the ASCON Group.
• CGAL is an opensource Computational Geometry Algorithms Library which has support for boolean operations on Polyhedra; but no sweep, revolve or NURBS.
• Open CASCADE is an opensource modeling kernel.
• sgCore is a freeware proprietary modeling kernel distributed as an SDK.
• K3 kernel is developed by Center GeoS.
• SOLIDS++ is developed by IntegrityWare, Inc.
• APM Engine is developed by RSDC APM.
• KCM is developed and licensed by Kubotek Kosmos
• SvLis Geometric Kernel became opensource and discontinued, for Windows only.
• IRIT modeling environment, for Windows only.
• GTS GNU Triangulated Surface Library, for polygon meshes only and not surfaces.
• Russian Geometric Kernel.
• Geometry Kernel, a multi-platform C++ library with source code accessible for clients, developed and distributed by RDF - Geometry Kernel web site.
• SolveSpace has its own integrated parametric solid geometry kernel with a limited NURBS support.
