Optimal normalized totally positive basis
WebIt was shown in [ 23] that tensor product surfaces generated by normalized and totally positive bases have the PIA property. We note in [ 22] that the - B-spline basis is normalized and totally positive; therefore, the initial - B-spline surface has the PIA property. Let http://jnaiam.org/uploads/jnaiam_6_7.pdf

WebOptimal Normalized Totally Positive basis (ONTP basis for short), in the sense of the B-basis [2]. Moreover, not only the ONTP basis shall exist in the spline space itself, but also in all other spaces derived from it by insertion of knots. Besides being crucial for the development of most geometric modeling algorithms, the WebSince the extension Bernstein basis functions given in form a group of (optimal) normalized totally positive basis functions, the corresponding -Bézier curves possess variation diminishing property, which means that no plane intersects -Bézier curve more often than it intersects the corresponding control polygon. 2.3.
