title = {{A}n {A}lgorithm for {S}ilhouette of {C}urved {S}urfaces {B}ased on
{G}raphical {R}elations},
abstract = {The proposed algorithm displays the projected surface S as a
quadrilateral grid of straight segments, g; any one of these can
be part of the silhouette if, and only if, the two patches
connected along g lie on the same side of it. The same segment g
is drawn, if it is not hidden by remote patches. The algorithm can
be applied to any surface regular or not and selfintersecting and
can display the entire silhouette or a part of it. It is simple,
it uses only the rectangular coordinates of the projected vertices
of the grid and requires few elementary mathematical operations.},
