INPUT/OUTPUT CURVE EDITOR

摘要

A method of varying the relationship between a scalar input parameter and a scalar output parameter shown as a curve (C) in figure 1. The input value is given along the horizontal axis, and the output value is illustrated along the vertical axis. The curve is moved by selecting one or more control points (10. Each control point having two handles (12, 14). The user can vary the shape of the curve by either moving the control points, or the handles in two dimensions (up or down, and left or right).
