Today I spent a large amount of time in the sound diffusion lab creating visuals in TouchDesigner. I had an idea of taking loads of lines and manipulating them to create a string vibrating effect. The easiest way of doing this was through instancing, which I learnt about through a tutorial by programming for people. You can watch it via > this link <
Through instancing you can take the points of a SOP and tell a Geometry Comp to use that to place more SOPs. This means you can take the points of a square and assign a circle to each of the points via the Geometry Comp. Which will result in 4 circles appearing at the points. I used a line with multiple points to placed lines next to each other. Then I used audio track to manipulate the points, so that you have multiple lines vibrating next to each other. Once that was rendered, I duplicated it and turned one on its side. To get the visuals to be small note, I used a composite TOP. So that they would show only where the lines intersect.
I am spending much time developing different visuals to use. I this will be the best way since I can refine it at a later stage. More visuals on the way...
