In this paper,an improved curve-fitting algorithm in term of the Bezier curve principle is proposed. By cutting the measured unorganized point-clouds in parallel, we obtain the cloud section. The Bezier curve with points is extracted from the sorted cloud section approaches to the cloud section. Experimental results show that this algorithm is effective, robust and can be easily implemented.

研究了在MFC中运用OpenGL进行编程,重构三维物体的方法.对于逆向工程三维重构的杂乱离散点云,在进行排序重组和三角网格化后,运用OpenGL对三角网格进行消隐,设定法线、光照和材质的处理,重构原始物体.具体的应用实例说明了所提方法的有效性.

从针对面向对象程序设计与图形处理各自的特点出发,采用面向对象的程序设计方法对图形系统进行分析,并运用快速逆向工程方面的三维点云软件设计的实例说明面向对象程序设计方法在图形处理中的应用.
