| 摘 要： | 在旋转的空间几何模型的Ｐｈｏｎｇ光照模型分析基础上，基于以往的二次曲面等灰度理论，提出了一种新的镜面反射模型和投影等灰度线生成算法，该算法很好地解决了典型二次曲面在三维空间旋转任意角度之后实时地生成Ｐｈｏｎｇ模型光照图象，为二次曲面图元接拼形体奠定了良好的基础。

| Abstract: | According to three dimension rotating geometric model and Phong BuiTuong's shading model , and based on the previous equi intensity principle, this paper describes a new specular reflection model and an improved real time algorithm generating a set of projective equi intensity curves on quadric surface. The algorithm solved the problem how to generate for real time Phong's shading images of typical quadric surfaces which rotated any angle. |
