A system for interactive computer graphics enables generation of Bezier curves from a series of points based on the relative position of successive points in the series. For example, for successive points in a series, point A, point B, and point C are successive points in the series of points, and wherein a control point corresponding to point B and associated with the segment AB is determined by the equation B + R A *( R A *(B-C) + R C *(A-B)), and a control point corresponding to point B and associated with the segment BC is determined by the equation P BBC = B + R C *(R A *(C-B) + R C *(B-A) ), where R A = |AB| / (|AB|+|BC|), and R C = |BC| / (|AB|+|BC|).
