摘　　要：高逼真度浓淡效果的生成需要巨大的运算量，这使其很难用于实时计算机成象（ＣＩＧ）系统．本文从几何角度出发，在对整个三角形面元进行角度的增量化线性内插基础上，提出了一种具有高光效果的浓淡图形实时绘制算法，并给出了其硬件实现方法．The simulation of lighting effects can efficiently improve the realism of pictures. But it has not been well used by real-time CIG systems because of the large amount of computation. In this paper, a new angular interpolation algorithm and its hardware implementation are presented for Phong shading polygons, which properly solve the problem of not generating highlight effects of smooth surfaces in modern real-time CIG systems.
