on the basis of this, we classified the traditional methods of 3-d visualization which base on the computer graphics algorithm, and delve into them . in the end, we deeply analysed the 3-d visualization which base on the method of volume rendering with a concrete software 在此基础上,我们对传统的基于计算机图形学算法的三维可视化方法进行了分类研究,并结合一个实际软件深入探讨了基于体绘制的三维可视化方法。
