Description

A rational Bézier curve is a parameterized curve of the form

where the functions

are the Bernstein basis functions of degree p, bi = ( x1, …,  xn) are the control vertices of the n-dimensional space, and wi are the weights, which should always be positive real numbers to get a properly defined rational Bézier curve. A rational Bézier curve has a direction defined by the parameter t.
