b spline

الإنجليزية - الإنجليزية

تعريف b spline في الإنجليزية الإنجليزية القاموس.

A particularly smooth class of approximating curves B-Splines are fully approximating: such a curve generally passes through its control points if several of them are in the same location B-Spline curves are converted to NURBS curves when imported into SOFTIMAGE|XSI

A very smooth curve controlled by three or more cv's The b-spline always intersects the first and last cv, but is usually only influenced by the others Image from Softimage

A cubic polynomial formulation with the potential for C(2) continuity, which provides a visually smooth curve, even though it does not generally pass through any of its control points

B-splines are a formulation (Barsky and Beatty, 1983) of B-spline curve segments Barsky introduced two new degrees of freedom- bias and tension- which cab be applied either uniformly to the whole curve or non-uniformly by varying their values along the curve
