Derivative of a bezier curve
Webillustrate the foundation upon which the Bézier curves are built. 2.2. Derivatives of spline functions. From de Boor (2001) we know that the derivatives of spline functions can be simply expressed in terms of lower order spline functions. In particular, for the Bézier curve we have B(l)(x)= n−l i=0 ´(l) i Bi,n−l(x), where ´(0) i =´i ...

Conditions for C1 continuity: Along with the constraints of C0 continuity, the curve has to follow additional condition that the 1st derivative of first curve at “t = 1” must be equal to the 1st derivative of the second curve at “t =0”i.e. r(1) = s ...
Let t denote the fraction of progress (from 0 to 1) the point B(t) has made along its traversal from P0 to P1. For example, when t=0.25, B(t) is one quarter of the way from point P0 to P1. As t varies from 0 to 1, B(t) draws a line from P0 to P1. For quadratic Bézier curves one can construct intermediate points Q0 and Q1 such that as t varies from 0 to 1:
