| Allegro CL version 6.2 Minimally revised from 6.1 |
Arguments: stream vertices
Draws one or more Bezier curves on stream. vertices should be a sequence (list or vector) of positions (see make-position) that indicate the starting, ending, and control points for the curves. Each curve is specified by four positions that indicate a starting point, two control points, and an ending point in that order. The ending point of each curve is re-used as the starting point of the next curve, and so vertices must contain (1+ (* 3 N)) to draw N curves (where N must be at least 1). For example, to draw two connected curves you need to pass a sequence of 7 positions, where positions 1 through 4 specify the first curve and positions 4 through 7 specify the second.
