Bezier Curves and Bezier Surfaces generation with C/C++ in Code::Blocks
Brief Theory of Bezier Curve
In order to draw curvy surface we implement Bezier curve algorithm. In drawing Bezier we first define n+1 control point pk = (xk, yk, zk) with k varying from 0 to n. And the coordinate points are blended to produce following position vectors that define the path of an approximation Bezier polynomial function between p0 and pn.

The Bezier blending functions BEZk,n(u) are the Bernstein polynomials: BEZk,n(u)=C(n,k)uk(1-u)n-k
Where the C(n, k) are binomial coefficients.
Equivalently, we can define Bezier blending functions with the recursion calculation.
BEZk,n (u) = (1-u) BEZk,n-1(u)+u BEZk-1,n-1(u), n>k?1
With BEZk,k = uk , and BEZ0,k = (1-u)k.
