WebMar 17, 2024 · The easiest way to get a random point in a circle is to use polar notation. With polar notation, you can define any point in the circle with the polar angle ( ang) and the length of the hypotenuse ( hyp ). For both, we can apply a random number generator to give us a value in a usable range. The polar angle will be in the range [0, 2 * pi] and ... WebOne way to implement this would be a 2500 x 2500 array of 0-1 which represent valid or invalid.
