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

I find myself, when I start a new project, spending a lot of time setting up a basic app before I get to the point where I can create something fun. I have to create a Rust application, set it up to use Nannou, create a basic Nannou app, test it to make sure it’s working (typos are inevitable, it seems). Then I have to add in any cool features I may have come up with from past apps I have done, which means remembering where I did it and copying in the code ..read more

I skipped over pants and shorts to get to the T-Shirt, so that my doll would have a top to go with her skirt. I chose a varigated yarn that I thought would match the skirt. IRL, it matches better than the photographs. The color changes didn’t work out as well as I hoped… I wanted the turquoise up higher on the shirt so it had a different color right next to the blue ..read more

Sol LeWitt was an artist who worked in many mediums. and was known for his association with the conceptual art and minimalism movements. As you know if you have been reading my posts here, I am interested in generative art. While Sol LeWitt was not a digital artist, he did do some interesting work in algorithmic art: his Wall Drawings . LeWitt believed that the idea behind a work of art, rather than the act of producing it, was the actual art work ..read more

The next article of clothing in the Crochet You book is a cute skirt with a scallop trim on the bottom. I liked this blue color with the hair and skin of the doll. I also have a varigated skein of yarn that I think will look cute used for a tshirt to go with it. The skirt is worked in continuous rows around, except for a few rows at the beginning ..read more
