【摘要】 Phong浓淡算法巨大的计算量一直是阻碍其广泛使用的最主要原因之一。为了以较低的代价实现类似的光照效果，本文提出了一种基于图象的环境纹理映射思想来实现实时的近似Phong效果的浓淡方法．采用预先定义的光照纹理与简化的纹理映射方法，使得本文的方法具有较高的效率，同时几乎不损失生成画面的质量，可以在低端系统中实现实时的仿Phong浓淡效果。更多还原

【Abstract】 The massive need for compating of the Phong shading method is the main obstacle to its population. To achieve similar effect with low cost, a new method is proposed in this paper based on environment texture mapping with predefined texture. And the result is a real-time fake Phong shading effect. Using predefined shading texture map and affine texture mapping method, the method is very effective, and can produce pictures with high quality. So the method is an effective way to get real-time fake Phong shading effect on low-end systems.更多还原
