| Abstract | In this work, Bezier approximation is used to define curves
and surfaces. This approximation is fairly versatile and
provides a strong intuitive feel for how to change or control
the shape of a curve or a surface. This can be seen from the
Bezier curve and surface equations:
[...]
The first equation is a conventional binomial distribution
of one parameter u, and the second of two parameters u and
w. Those two equation can be written in matrix form, so the
computed results can easily be transformed into plot array for
drawing the images on the computer output devices.
A subsystem, Build world, enables the user to prepare a 2D or
30 geometric model and to change the viewing parameters, to view
the image from different angles. Also it provides two kinds of
procedures: first, to generate curves or surfaces of a geometric
model of an object by using user specified data control points,
and the second, by using the existing data (the data also can be
modified).
The input to these procedures consists of the number of
control points p, the number of points on the curve n and the
control points coordinates. |
