WebApr 3, 2011 · 30. Generate a random point inside a circle of radius 1. This can be done by taking a random angle phi in the interval [0, 2*pi) and a random value rho in the interval [0, 1) and compute. x = sqrt (rho) * cos (phi) y = sqrt (rho) * sin (phi) The square root in the formula ensures a uniform distribution inside the circle. WebNov 14, 2014 · Then simply call that in a list comprehension to generate however many points you desire. points = [random_point_within(poly) for i in range(5)] checks = [point.within(poly) for point in points] My approach is to select x randomly within the polygon, then constrain y.
