Extended cubic uniform B-spline and sweep surface in three dimensional graphic objects / Nursyazni Mohamad Sukri and Noor Khairiah Razali

Spline curve and surface is widely used in Computer Aided Design (CAD) and Computer Aided Graphic Design (CAGD). Extended cubic B-spline is one of the techniques that can be applied in design system or create new objects. Besides, three-dimensional object such as glass, pot, and top and so on can be generated from Extended Cubic B-spline curve by using sweep surface method. Surface sweep technique is widely used in geometry model. Extended cubic B-spline curve can be used and applied in this area as alternative to other curves such as Bezier curves B- spline curves and T-spline curve. Objectives of this project are to study about an extended cubic uniform B-spline curve and sweep surface. Then form the object in the three-dimensional by using an extended cubic uniform B-spline curves and sweep surface method such as revolution. The shape or object is analyzed by using different degree of Extended Cubic B-spline curve and different value of parameter curve λ. The variety shape of curve can be formed by changing the degree and value of shape parameter λ .
