This paper improved the traditional hidden line removal algorithm in a 3D solid scene: the Roberts algorithm, by integrating a new data structure into the traditional Roberts algorithm. In the end, implemented the hidden line removal algorithm which could meet the special requirement of outputting the hidden lines in the form of dotted line as the traditional solid geometry teaching does.
