提出了计算曲面着色图片的过程。表面由小多边形近似，以便轻松解决隐藏部分问题，但计算每个多边形的阴影，以便消除整个表面上阴影的不连续性，并获得平滑的外观。为了实现速度效率，使用了沃特金斯开发的技术，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.
