Abstract
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*(R*(B−C)+R*(A−B)), and a control point corresponding to point B and associated with the segment BC is determined by the equation P=B+R*(R*(C−B)+R*(B−A)), where R=|AB|/(|AB|+|BC|), and R=|BC|/(|AB|+|BC|).
