The algorithm presented causes the elimination of hidden lines in the representation of a perspective view of concave and convex plane-faced objects on the picture plane. All the edges of the objects are considered sequentially, and all planes which hide every point of an edge are found. The computing time increases roughly as the ... how did guthix die
