The points module
Contents
The points module¶
This notebook demonstrates how to use the randomly.points module.
Note
This assumes you have already installed the randomly package.
Poisson points¶
Currently, the module only contains a single function, generate_poisson_points(). This function will generate random points in a defined rectangular space.
The function accepts two parameters:
bounds: a tuple(minx, miny, maxx, maxy)of the bounding box.rate: theoretical events per unit area
from randomly.points import generate_poisson_points
Let’s generate random points within a 100 x 100 square with origin at (0, 0) at a rate of 0.01 (1%).
points = generate_poisson_points(bounds=(0, 0, 100, 100), rate=0.01)
With an area of 10,000 square units, we would expect about 100 points. If we look at the shape of the output array, we should see somewhere around 100 points represented.
points.shape
(93, 2)
Our points variable is a set of X-Y coordinate pairs.
