Bezier surface

(graphics)A surface defined by mathematical formulae, used incomputer graphics. A surface P(u, v), where u and v varyorthogonally from 0 to 1 from one edge of the surface to theother, is defined by a set of (n+1)*(m+1) "control points"(X(i, j), Y(i, j), Z(i, j)) for i = 0 to n, j = 0 to m.

P(u, v) = Sum i=0..n Sum j=0..m [

B(i, n, u) = C(n, i) * u^i * (1-u)^(n-i)

C(n, i) = n!/i!/(n-i)!

Bezier surfaces are an extension of the idea of Bezier curves, and share many of their properties.
