Bézier techniques for triangular patches simple task to derive algorithms which evaluate, degree elevate, reparametrize, or subdivide a triangular surface in Bézier representation. The generalization of the techniques described for univariate polynomials in Chapter 3 is straightforward.

Stationary subdivision for arbitrary netsk presented a similar generalization for bicubic splines. Their algorithms can be applied to arbitrary quadrilateral control nets and yield sequences of control nets that converge to piecewise biquadratic or bicubic surfaces with finitely many so-called extraordinary points.

Stephen Hutchings,Kenzie Burchellcal or only complicated descriptions are known. To construct such a representation, one usually measures or evaluates a given curve at a number of points and determines an interpolant or approximant. This chapter reviews some basic techniques.

Jason R. Finley,Farah Naaz,Francine W. Gohuence, there are simple efficient knot insertion algorithms to convert a B-spline representation to a B-spline representation over a finer and also evenly spaced knot sequence. Moreover, these algorithms are the prototypes for the class of the so-called ..
