Fill a polygon with hachure lines using the AET scan-line algorithm

Usage

hachure_fill(
  px,
  py,
  hachure_gap = 0.1,
  hachure_angle = 45,
  roughness = 0,
  bowing = 0,
  seed = NULL
)

Arguments

px, py: Polygon vertex coordinates in inch space. May be open or closed.
hachure_gap: Spacing between fill lines (inches). Default 0.1.
hachure_angle: Fill angle (degrees). Default 45.
roughness: Roughness applied to each fill line. Default 0 (straight).
bowing: Bowing applied to each fill line. Default 0.
seed: Integer seed.

Value

A list of 2-column (x, y) matrices, one per fill line (roughened if roughness > 0, otherwise two-point straight segments).
