Generalized B-spline bases are generated by monotone increasing and continuous “core” functions; thus generalized B-spline curves and surfaces not only hold almost the same perfect properties which classical B-splines hold but also show more flexibility in practical applications. Geometric iterative method (also known as progressive iterative approximation(More)
The concept of generalized B-spline basis function was extended by considering monotone increasing continuously differentiable nonlinear core functions instead of the classical linear one. It is not only compatible with classical B-spline basis function but also provides plentiful curves and surfaces for geometric modeling system. This paper takes(More)
