Because we mainly involve visual fields of medical science , have placed more contents on the development in the field of medical image of visual technology and argumentation used. Second part It is the visual technology knowledge, the generalization in such respects as the basic principle , basic functions, function store and three-dimensional animation technology to OpenGL ,etc. The realization of the system using OpenGL functions finish that three-dimension demonstration. The third part It is number value that calculate knowledge, three-dimension rebuild technology is it is it is it punish to fit to go on to need, the research of interpolator technology that cant leave, So this part has quoted the Hermite function principle , define cubic Hermite function to begin, calculate the differential coefficient among them draws cubic spline again.
由于我们主要是涉及医学可视化领域,所以将更多的内容放在了可视化技术在医学影像领域的发展与应用的论述;第二部分是可视化技术方面的知识,主要对 OpenGL 的基本原理、基本功能、函数库及三维动画技术等方面的概括,在系统实现时就是通过调用 OpenGL 函数库实现三维显示的;第三部分是数值计算方面的知识,三维重建技术需要进行拟合处理,离不开插值技术的研究,所以这一部分从埃尔米特函数原理开始讨论,引入三次埃尔米特函数,进一步计算时又引用三次样条函数。
