erase-polygon

Arguments: stream vertices

Erases (i.e. replaces with the background color or texture) the specified polygon from stream. A polygon is specified by vertices, which should be a sequence (list or vector) of positions (see make-position). A line is drawn connecting the first vertex with the final vertex. stream should be a cg-stream.

Contrast with draw-polygon which draws the polygon on stream.
