Ich habe die beiden Methoden überprüft und Matplotlib sieht viel schneller aus.
Code: Select all
from time import time
import numpy as np
import matplotlib.path as mpltPath
# regular polygon for testing
lenpoly = 100
polygon = [[np.sin(x)+0.5,np.cos(x)+0.5] for x in np.linspace(0,2*np.pi,lenpoly)[:-1]]
# random points set of points to test
N = 10000
points = np.random.rand(N,2)
# Ray tracing
def ray_tracing_method(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
