摘　　要：三维真实感浓淡绘制方法是三维可视化技术中一项重要的研究课题，本文针对其中具有重要实用价值的距离梯度浓淡绘制方法进行了深入研究，提出了自适应曲面拟合浓淡绘制方法，使浓淡绘制效果获得了显著提高，为医学图像三维可视化技术在微机领域的应用提供了理论和算法基础．Shading is one of the important research themes in 3D visualization. In this paper, the Z-buffer gradient shading method, which is of great important practical value, is deeply investigated and a new shading method named adaptive surface fitting for shading is proposed. The new method can notably increase the shading quality. The study provides the theoretical and algorithmic foundations for the applications of 3D visualization of medical images on microcomputer systems.
