Abstract:
A method to display a projected parametric curve upon a substantially transparent windscreen head-up display includes monitoring a desired parametric curve comprising a plurality of control points and a plurality of graphic segments based upon the control points, determining a luminance indicator for each of the segments, and utilizing the luminance indicator to command uniform luminance among the plurality of graphic segments.
