Bernstein polynomial

(polynomial form capable of producing arbitrary shapes)

Bernstein polynomials constitute a family of polynomials capable of approximating arbitrary function curves, sometimes used as basis functions in modeling. In the manner of a Fourier series expansion or Taylor series expansion, they offer a way to build a polynomial approximation of an arbitrary curve over a given finite interval.

One use is to produce arbitrary statistical distributions nonparametric model in Bayesian statistics.

I imagine they are a means to produce efficient expressions for calculating approximations of functions, which can be helpful in computer graphics, particularly real-time computer animation, and also in increasing the efficiency of computationally-intensive numerical models.
