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]
