Development of CAD Algorithms for Bezier Curves/Surfaces Independent of Operating System

摘要

Most of the CAD software, which are available currently, works only on the operating system (generally windows) for which they are designed. Alternatively, the commercial CAD software is dependent upon the operating system. If CAD software is designed such that it is Independent of the operating system, then such CAD software will be much beneficial for the present scenario of the CAD softwares and it will be independent of the operating system. Now-a-days most of the commercial software use application programming interfaces (APIs) which provide libraries of common graphics operations that allow developers to incorporate many more realistic effects into their applications. But the CAD software is dependent on the Operating System, which is the major drawback of the software. There is a need to develop the CAD algorithms independent of operating system so that the same can be used for the development of any CAD software. Keeping this in view, the present work is devoted to the development of CAD algorithm for the Bezier curves and Bezier surfaces. The algorithms are independent of the operating system. The operating system independent graphics library OpenGL has been used for the development of these CAD algorithms.
