探讨了一种利用平面迹线和几何作图法,作无灭光线下透视阴影的新方法。该作图法理论易于理解,作图简便,占用图面小,是比较实用的方法。
A new method for rendering perspective shadows under invisible light is explored using plane traces and geometric mapping. The drawing method theory is easy to understand, the drawing is simple, and the drawing surface is small. It is a practical method.
