Remember, there’s no such thing as a silly question, so don’t hesitate to reach out, we love hearing from you!
Sometimes, we want to make something out of nothing! In this project, we'll create our own shapes, split their color channels, distort them, and put them back together again! We will then remap the colors to align harmoniously with a bespoke color scheme of your own design.
What exactly can we do with this project? Let's find out! P.S. If you're wondering about the name, it's from the musical pattern of a sequence of chords.
Firstly, let's set up our project with our display layout, so we have a better view when it comes to making our project.
We could create our own shapes in an image program but luckily TouchDesigner has a bunch of defaults we can use quickly!
Blending and compositing may be familiar from other image editing software such as Photoshop... here we can blend several textures together using Composite
Every texture is made from red, green, blue, and alpha channels and we can alter and change their power using Channel Mix
In the last project, we distorted a whole texture using noise. Now we can distort individual color channels separately and then composite them back together again!
Smooth noise is nice but what about a different, bolder effect? Using Limit, we can round areas to an average color so we can distort in a boxy way.
What if we like the general look but not the color scheme? Let's introduce ourselves to the Lookup and Ramp TOPs to take an input's brightness and map it to a new color!
What about other shapes? How do letters look when you distort them too? Turns out... it looks pretty good!
Introducing Channel Operators... or CHOPs for short. These are ways to control singular parameters, usually numbers, that make our artwork look less static.
Channel Operators can be used for a range of parameters, including Texture Operator parameters that we've covered elsewhere. Here we alter the displacement weighting on a Displace TOP!
Another simple effect we can use is by altering the noise TOPs to make them just a pixel in height (or width) and TouchDesigner will stretch this pattern to give us a slit scan effect.
Sometimes, your output can look a little flat, especially when you're making textures from scratch, so to give it some life, we can add a touch of static noise over the top to give our artwork some depth.
