In this thesis, we consider isoparametric curves of quadratic F-Bézier curves. F-Bézier curves unify C-Bézier curves whose basis is ｛sint, cost, t, 1 ｝and H-Bézier curves whose basis is ｛sinht, cosht, t, 1｝. Thus F-Bézier curves are more useful in Geometric Modeling or CAGD(Computer Aided Geometric Design). We derive the relation between the quadratic F-Bézier curves and the quadratic rational Bézier curves. We also obtain the geometric properties of isoparametric curve of the quadratic F-Bézier curves at both end points and prove the continuity of the isoparametric curve.
