摘要
在一光源照射下,立体的受光面和阴面之间必存在一条分界线,即立体的阴线,仑的轨迹直接决定立体的投射阴影.这里分别针对单个的平面凸立体和曲面凸立体两种不同情况,提出了求解凸立体表面阴线,并在此基础上确定投射阴影的不同方法.
On a volume illuminated by a light, there is a boundary between illuminated and shade face. This boundary named shade line resolves direcdy projected shadow of volume. In accordance with two kinds of volume, different methods are presented to calculate shade lines and projected shadow.
