Abstract: Ruled surface design and its applications are widely used in CAGD (computer aided geometric design) and industrial areas. The dual De Casteljau algorithm [K. Sprott et. al., (1997)] is for ...

The user creates a control polygon by clicking anywhere on the screen. This would create a new point. Pressing '0' would just show the control polygon, pressing '1' would show the bezier spline, ...

Periodic Hermite spline interpolants on an equidistant lattice are represented by the Bézier technique as well as by the B-spline method. Circulant matrices are used to derive new explicit formulas ...
