'Subdivision' is a way of representing smooth shapes in a computer.
A curve or surface (both of which contain an in?nite number of
points) is described in terms of two objects. One object is a
sequence of vertices, which we visualise as a polygon, for curves,
or a network of vertices, which we visualise by drawing the edges
or faces of the network, for surfaces. The other object is a set of
rules for making denser sequences or networks. When applied
repeatedly, the denser and denser sequences are claimed to converge
to a limit, which is the curve or surface that we want to
represent. This book focusses on curves, because the theory for
that is complete enough that a book claiming that our understanding
is complete is exactly what is needed to stimulate research proving
that claim wrong. Also because there are already a number of good
books on subdivision surfaces. The way in which the limit curve
relates to the polygon, and a lot of interesting properties of the
limit curve, depend on the set of rules, and this book is about how
one can deduce those properties from the set of rules, and how one
can then use that understanding to construct rules which give the
properties that one wants.
