Geometric modeling kernel

A geometric modeling kernel is a solid modeling software component used in computer-aided design (CAD) packages.[1][2] Available modelling kernels include:

• ACIS is developed and licensed by Spatial Corporation of Dassault Systèmes.
• SMLib is developed by Solid Modeling Solutions.[3]
• Convergence Geometric Modeler[4] is developed by Dassault Systèmes.
• Parasolid is developed and licensed by Siemens.
• Romulus was a predecessor to Parasolid.
• ShapeManager[5] is developed by Autodesk and was forked from ACIS in 2001.
• Granite[6] is developed by Parametric Technology Corporation.
• C3D Modeler is developed by C3D Labs, part of the ASCON Group.[7][8]
• 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.[9]
• K3 kernel[10] is developed by Center GeoS.
• SOLIDS++[11] is developed by IntegrityWare, Inc.
• APM Engine[12][13][14] is developed by RSDC APM.
• KCM[15] is developed and licensed by Kubotek Kosmos[16]
• SvLis Geometric Kernel became opensource and discontinued, for Windows only.
• IRIT modeling environment, for Windows only.[17]
• GTS[18] GNU Triangulated Surface Library, for polygon meshes only and not surfaces.
• Russian Geometric Kernel.
• Geometry Kernel,[19] a multi-platform C++ library with source code accessible for clients, developed and distributed by RDF - Geometry Kernel web site.
• SolveSpace application has own integrated parametric solid geometry kernel with a limited NURBS support.
