| Summary: | 碩士 === 元智大學 === 電機與資訊工程研究所 === 82 === Often plotting or conversion packages do not use high-
resolution output devices efficiently. Where such packages use
very large point file to describe a plot. In this thesis, we
will propose a new method which produces a conic spline to
approximate the parametric function which could be represented
by R(t) = [ X(t),Y(t) ]. We choose the knot in the inflection
point which makes the splited segments as less as possible. And
we select the conic spline as the primitive curve, because it's
simple, fast in computing time, and flexible. The most
important problem in this thesis is to find the accurate value
of cusps and inflection points to be the knots. We'll discuss
that in the approximte conversion steps.
