Volume visualization is a joint between VISC and 3D GIS, the prospect of which is summarized in this thesis. And two basic algorithm on visualization of 3D data are expounded: Surface-fitting method and Direct Volume Rendering(DVR).

• 三维可视化是科学计算可视化和三维GIS密切联系的纽带，本文综述该方面的发展趋势，研究了两大类三维数据场可视化算法：表面拟合方法(Surface-fitting method)和直接体绘制(Direct Volume Rendering，DVR)。
