摘要
本文论述了直线与超曲面相交及其可见性问题。编制了通用程序,并由计算机绘制出投影图;这不仅使投影图更清晰、直观,而且对几何作图也有参考意义。
The article discusses the intersection of straight-line and hypersurface and its visibility problem. Generalpurpose program is worked out and projections are drawn bycomputer. This makes the projections clearer, more audio-visualand is also of value to geometry drawing.
