| Abstract: | Complex quadratic B-spline curves defined on unit circular arcs are suggested for CAGD, and some geometrical propelles, completely different from the case of real curves,are discussed. Actually, the curves consist or Pascal cochleoids piecewiscly with O1continuity. By adjusting the location of the control venices, some segments of the curve may be circular arcs. |
