New minimal bounds for the derivatives of rational Bézier paths and rational rectangular Bézier surfaces

作者:

Highlights:

• New minimal bounds are derived for the magnitudes of the derivatives of rational Bézier paths and surfaces.

• The derived minimal bounds are for a generic and well-known type of pointwise bound.

• Simple, explicit closed-form expressions are obtained for the minimal bounds.
