摘要
本文介绍了一种基于工程素描的真实感显示方法，并把这一方法运用于曲面造型中。真实感显示采用了简单的光照模型。光线采用常光、图形消隐依据近的东西可能遮挡远的东西、曲面自身的表面法向采用Ｒｏｂｅｒｔｓ方法确定。点和线的产生主要是运用加以改进的扫描线算法。
A method of stimulating real objects based on engineering sketch is presented.this method used to display some 3-D geometry objects.The simple illumination model is used.Hidden line algorithm is based on the idea that something near might hind the farther.The N-vect of the patch is counted by Roberts,The producing of dot and line is based on the scan line method.
