This post is going to be more about Rust than about art. You have been warned! As I was working on moving the Hyphae code into TAHGA Lib , I found too much complexity and repetition in what I had done before. What I was doing to modularize it for the library was making matters worse. The problem was that I needed a structure to define a hypha, a single strand that grows over time until it dies ..read more

Those of you who are paying close attention (all of you, I am sure…) may have noticed that things are getting just a bit unwieldy. Two recent posts, The Return of the Boids and Flying Triangles , both use the Boids algorithm. Likewise, two other posts, Watercolor Stroke and Revisiting the Watercolor Stroke , both rely on the Watercolor Stroke code. What’s more, the Watercolor Stroke is intended to be used in several future projects ..read more

I recently did a post about the watercolor stroke, a method to add a color wash along a line. I’ve extended this to use multiple colors. You can still pass it just one color as before, using the color() method. But now there is also a colors() method by which you can pass in any number of colors. Watercolor stroke will choose a color from the list at random, and will use that color until one of two things happens ..read more

Today, I’d like to try something and see how it works out. Using the Boids work I did recently as a starting point, I’m wondering if I could get something interesting if I grouped boids into groups of three, and instead of drawing the boids themselves, draw the triangles defined by the positions of each boid in each group of three. I’m not sure how well that will work, but let’s give it a try ..read more

You may have noticed that, in my Nannou apps, I tend to use hsla colors. hsla is hsl plus an alpha channel, a, to control transparency. The hsl part defines the color. hsla stands for hue, saturation and lightness. In this color model, hue is the color itself. You can think if it as being chosen from a color wheel. In many implementations, this number is a number of degrees (0 to 360) or radians (0 to 2pi ..read more

Recently, I had an idea about adding a color wash to a line. Suppose, in real life (not digitally,) I made a line of watercolor paint on some paper. Then suppose I took a very fine brush and smeared the paint at right angles to the line. I could go down the line and smear each part of it a different amount. This being watercolor, the darkness of the color in the smear would be greatest if I smeared it just a little, but if I smeared it a lot, the color would become quite light ..read more

A while back , I wrote an article about Boids , a flocking algorithm. I didn’t actually implement it at the time; I just talked about it. Now I have some ideas for using it to create some interesting art, so I thought I’d implement it in Rust and Nannou. There many examples of Boids implementations on the internet. Mine is a straightforward translation of Ben Eater's javascript example into Rust ..read more
