Уважаемые Гуру!
Есть функция на python, реализующая отнесение точки к полигону
# determine if a point is inside a given polygon or not # Polygon is a list of (x,y) pairs.
def point_inside_polygon(x,y,poly):
n = len(poly)
inside =False
p1x,p1y = poly[0]
for i in range(n+1):
p2x,p2y = poly[i % n]
if y > min(p1y,p2y):
if y <= max(p1y,p2y):
if x <= max(p1x,p2x):
if p1y != p2y:
xinters = (y-p1y)*(p2x-p1x)/(p2y-p1y)+p1x
if p1x == p2x or x <= xinters:
inside = not inside
p1x,p1y = p2x,p2y
return inside
#Test point_x = 0.001
point_y = 0.001
polygon = [ (1, 1), (2, 2), (3, 3), (4, 4), (1, 1) ] print point_in_poly(point_x,point_y,polygon)
Мой bash сценарий формирует point_x point_y. Как Python скормить точки из bash.
