| Abstract | This study was carried out with the main objective of establishing the relationships between
Bezier, Chebyshev and Legendre curves. These relationships are obtained using the polar
form approach with mathematical derivations. They can serve as convenient ways to convert a
curve in a given form into the other two remaining forms.
It was found that
the control points of a curve given in one of the forms Bezier, Chebyshev and Legendre,
can be expressed as affine combinations of the control points of in each of the remaining
forms for the rational case. This result is not true for non-rational curves.
the control points of a Chebyshev or Legendre curve do not provide any hint about the
shape of the curve defined by them. This is completely different from the case of Bezier
curves.
In view of these results, it seems that when a curve is given in the Chebyshev's or Legendre's
form, it should be converted into the Bezier form so that its shape can be roughly figured out
before any drawing is carried out.
