Computational Arts by Matthew Brown

Continuing on from the original walking lines I did in Processing, I went on to develop this version of it. This is done effectively the same way as the original, but the code is cleaner and it provides for more variation. It also runs slower.

This version should allow further development to make the lines even more random by separating all the variables, where the original was more limited since the numbers were largely defined within the line parameters.

This version is also technically more stochastic then the first one as well as the lines are added to and built on using the += command to add the new line position to the previous line position. Unfortunately this still draws a new line every frame that is not necessarily joined to the line from the previous frame.

In the week 2 tutorial for KKB211 - Computational Arts 2, we are looking at doing walking lines in our chosen development tool.

Walking lines are effectively randomly generated paths that the lines follow to create a random image.

I have been using Processing for this particular focus. Thus far I have random lines, however they don’t follow any particular path as of yet. This is effectively still walking lines as the position of the lines is added to and built on. Unfortunately this actually draws a new line every frame that is not necessarily joined to the line from the previous frame.

Have a look at it online here.

The code used to do this is extremely simple and just involves a few random variables based on the width and height of the canvas. I don’t believe this is entirely stochastic because the randoms are tightly controlled, but it is random within its boundaries (unless you want to get into the nitty gritty of it, which I don’t).

The source code is available after the jump.

Last semester this blog was focused on my ongoing computational arts development for my uni work as part of the KKB210 - Computational Arts 1 subject.

This semester, I am moving on to KKB211 - Computational Arts 2, so again, this blog will be used as an online portfolio of my development in the area of computational arts. The aim is to develop a series of works by the end of the semester that can be used as exhibition pieces as part of a computational arts exhibition at QUT Kelvin Grove.

It will also act as a process diary to help my keep track of my development and help me filter out the not so good works so I can focus more on the ones that are worth pursuing.

Portfolio Item 1 -

• Audio Responsive Particles.

Portfolio Item 2 -

• Audio Responsive Lines.
  

Portfolio Item 3 -

• Kaleidoscope.

Just a minor fix to the draggable box I made the other day. Previously it positioned the box so that the top-left corner was aligned with the mouse. Now, it centres the box horizontally and vertically behind the mouse.

It is available online here along with the full source code.

The changes made to fix this are pretty simple, and the code changes are shown below.
