Definitions for "B-Spline"
B-spline (basis spline) is a kind of spline generated by so-called basis functions. The advantage of B-splines over Bezier curves (which are a special case of B-splines) is that the control vertices (CVs) of a B-spline affect only their local region of the curve or surface.
a mathematical, parametric definition of a series of connected geometric curve segments
a parametric curve (a curve defined by coordinates derived from functions sharing a common parameter) whose shape is determined by a series of control points whose influence is described by basis functions
