Instead of glitching pixels randomly you could use a counter, or geometric function (sin, cos, etc) in the loop to glitch pixels in mathematical patterns. Some ideas for experimenting with this script might be changing the mixPercentage randomness, or, as I did, adjust the random color to be less random by replacing any of the three random(255) with a number between 0 and 255.
I also added some commented out lines that illustrate how to apply filters to the entire image in Processing, uncomment them to see how they affect the result. In short, this script creates lines of random length and of random colors and mixes them into the original image. Img.pixels = lerpColor(pixelColor, randomColor, mixPercentage) įor the featured image of this post I adjusted the random color generator to always use 255 (the maximum) blue and thus the resulting image contains colors from the cool range of the spectrum. mix colors by random percentage of new random color percentage to mixįloat mixPercentage =. 5 and 1, and uses this as a mix ratio to mix the random color with the current pixel’s color. The sketch generates another random number, this time between. This means that each line of glitched pixels will have a new random color available to it.
The sketch generates a new random color for the randomColor variable before glitching any pixels and each time a pixel is not glitched. This type of structure will result in lines of glitched pixels, rather that just randomly positioned glitched pixels, which ends up looking like static. It also keeps track of whether or not the previous pixel was glitched by setting the previousPixelGlitched variable to true or false, if it was, there’s a higher chance that the code will glitch the current pixel. For each pixel in the image the script generates some random numbers to determine whether or not to glitch that pixel. In the simple glitch sketch we’re doing a little more.
In the script, which are referred to as sketches in Processing, you’ll need to change the following lines to point the script at the image you want to pixel sort: // image path is relative to sketch directory I’ve written a simple script you can download here, you’ll have to unzip it once it’s downloaded. Once you’ve installed and opened Processing you can load the script by accessing the menu.Īnd navigating to the SimpleGlitch.pde script file.
To get started download and install the latest version of Processing, version 3.1.1 at the time of writing this.
