给出了一种计算曲面阴影图的方法。为了方便地解决隐藏部分的问题，用小多边形来逼近曲面，但计算每个多边形的阴影，以消除曲面上阴影的不连续性，从而获得平滑的外观。为了达到速度效率，使用了Watkins开发的技术，使得该算法的硬件实现成为可能。
A procedure for computing shaded pictures of curved surfaces is presented. The surface is approximated by small polygons in order to solve easily the hidden-parts problem, but the shading of each polygon is computed so that discontinuities of shade are eliminated across the surface and a smooth appearance is obtained. In order to achieve speed efficiency, the technique developed by Watkins is used which makes possible a hardware implementation of this algorithm.
