<<CodeList>> GM_KnotType {Analysis}
Documentation
A B-spline is uniform if and only if all knots are of multiplicity 1 and they differ by a positive constant from the preceding knot. A B-spline is quasi-uniform if and only if the knots are of multiplicity (degree+1) at the ends, of multiplicity 1 elsewhere, and they differ by a positive constant from the preceding knot. This code list is used to describe the distribution of knots in the parameter space of various splines. The possible values are:
¾ uniform: the form of knots is appropriate for a uniform B-spline.
¾ quasiUniform: the form of knots is appropriate for a quasi-uniform B-spline.
¾ piecewiseBezier : the form of knots is appropriate for a piecewise Bezier curve.
