1 Introduction
Triangulations of a point set have been intensively stud
ied in computational geometry in these years. Triangu
lations are very important not only from the viewpoint
of their applications to computer graphics, numerical
analysis but also from a fact that triangulations are yet
another fundamental structure in discrete geometry like
hyperplane arrangements.
Our group has developed many systems concerning
triangulations. Specifically,
ffl minimum weight triangulation of a planar point set
ffl enumerating all triangulations of a planar point set
ffl uniform generation of triangulations of a planar
point set
ffl enumeration of all regular triangulations of a point
set in general dimensions
In this video, we demonstrate our results of the above
mentioned problems, mainly using animation.
