If you’re using Math.random or something similar that generates a random number, you’re probably getting a uniform distribution. So what might be better? Taking it slowly, let’s just try a different random. But seriously, I hope your skills and self-expectation rise above this level really quickly.

Maybe in my very, very early days of experimenting with graphic code I thought this looked kind of cool. And I could generate 10,000 individual “art works” like any one of these with a few lines of code. Here’s 10,000 random points:Īnd 500 random squares with random sizes: Randomly draw 10,000 of the same shape, you’re a generative artist.” But honestly I think that’s the ultimate in boring, lazy generative art. I once said something like, “If you can draw a shape, you’re an artist. So what, in my opinion, is a good use of random and what is not? Random positions and sizes No, Math.random is not a useful PRNG since you cannot seed it. In my bljs library, I had to build my own PRNG because one doesn’t exist in JavaScript.

In my blgo library I have a random module with all kinds of useful functionality that derives from Golang’s built-in pseudo random number generator (PRNG). But it can be lazy, and it can definitely be boring. Now of course I don’t actually think random is evil. So I thought I’d expand my thoughts on it. Interestingly, this was the part of the post that generated the most comments – only a few, but it was definitely the thing that several people latched onto. But once you find something interesting, lock in those parameters and start focusing. It’s OK when you have a formula and you’re searching for an interesting range of input parameters. Random is OK when you’re starting a new piece. In a recent post I shared some thoughts about art and included a few, somewhat tongue-in-cheek comments about the use of random number generation.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The visible light images in this sequence were acquired using the narrow angle camera on Apfrom a distance of approximately 1.2 million kilometers (700,000 miles) from Saturn.

Several background stars are seen moving across the field during the movie. The gores, together with the sheared-out material due to differential orbital motion, create the dark, diagonal drapes. The material closer to Prometheus orbits the planet faster than the material closer to the bright F ring core. With time, the ring material previously affected falls behind so that on the next apoapse passage of Prometheus, a new gore in the inner ring material is made. It is during these apoapse passages that Prometheus has its greatest influence on the fine ring material.

The moon passes comes closest to the ring at “apoapse”, when it is farthest from Saturn. Prometheus orbits closer to Saturn, and thus faster, than the icy particles that make up the F ring. Radial structure in the bright core of the ring is visible throughout the movie. Prometheus appears first in the sequence, interior to the F ring, and Pandora (84 kilometers, 52 miles across) follows along outside of the ring.
