Here we see three Bezier curves defined in the sides of a triangle [ABC]. We use a curve from three points in a plane. Start with three arbitrary points, A, B, and C. Draw a segment [AB] and [AC] and divide it evenly into n_A parts. Draw a line from A to B. Draw another from the point next to A to the point next to B. Continue until you go from B to C. We proceed as the same way to points B and C. If we increased the values of n_A , n_B and n_C we have a pattern created by the union of "three curves", each of them is a close approximation of a Bezier Curve using three points.
