The Research And Development Of A CAD/CAM Platform Foundational Part Based On ModelMagic3D

In general, CAD/CAM software providers don't provide the system source code to the users, but they only provide the limited interfaces for user to develop, which may not meet the users' practical needs and may limit the users' creativity greatly. This thesis introduces the ModelMagic3D system with the complete open source code. Based on this system framework and feature, we will modify and expand it to become our CAD/CAM platform that will finally satisfy our requirement.In this thesis, firstly, we will introduce the ModelMagic3D system framework and the program workflow in details, and analysis the main framework and it's main program though the examples. This establishes a foundation for the development of our CAD/CAM platform. Secondly, we will study the Non-Uniform Rational B-Spline(NURBS) interpolation algorithms and expand the curve/surface interpolation functions to the ModelMagic3D platform, so that the geometry modelling functions of our experimental CAD/CAM platform are expanded. Thirdly, in order to achieve the data exchange with other CAD/CAM platform, the methods of constructing the basic solid elements and designing the data structure will be proposed in the article. Finally, the virtual reality technology will be used in this experimental platform. Typically, the 3D stereo display and the space mouse will be introduced and developed for use in the future research carried on in this platform.
