== Macro-Parametric Approach for CAD Translation ==

The Macro-Parametric Approach (MPA) for CAD Translation is a way to achieve compatible CAD model exchange among a variety of CAD systems.

We are studying how MPA might be used for converting diverse CAD models into X3D form.

To learn more about MPA, please to go to the [http://www.macro-parametrics.org Macro-Parametric Approach] website.

The person in charge of MPA for X3D is currently YooKyung Jo, [http://icad.kaist.ac.kr iCAD Lab].

== Steps involved in translation ==
[[Image:Picture2.png|thumb|X3D translated file as viewed in BS Contact viewer]]
* Neutral XML file representing a parametric model is generated from various CAD systems' pre-processor programs using MPA.
* This neutral XML file is parsed by a central application called TransCAD which comprises of modules of [http://www.spatial.com/products/3d-acis-modeling ACIS], [http://www.techsoft3d.com/products/HOOPS-3D-Framework HOOPS], Constraint Manager, and Persistent Naming.
* With the help of ACIS APIs, an explicit representation (facets) of the model is generated
* These facets are then structured into a Delaunay Triangularized mesh using [http://tetgen.berlios.de TETGEN]
* The mesh is then optimized by decimating the mesh and maintaining a decent enough visual quality using various algorithms in [http://meshlab.sourceforge.net MeshLab]
* Finally, meshes are rendered in X3D using [http://www.web3d.org/x3d/specifications/ISO-IEC-19775-1.2-X3D-AbstractSpecification/Part01/components/geometry3D.html#IndexedFaceSet IndexedFaceSet].
