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 在此基礎上,我們對傳統(tǒng)的基于計算機圖形學算法的三維可視化方法進行了分類研究,并結合一個實際軟件深入探討了基于體繪制的三維可視化方法。
