Live VJing
Following the evolution from the previous section ‘Audio Reactive’ I mapped my Midi controller to a wide range of parameters in TouchDesigner, allowing me to influence the colour, geometry and background in real time.
I implemented more audio reactivity by linking the amplitude of the procedural noise that drives the geometry motion to the audio signal. I also mapped the strength of this audio reactivity to a dial on my midi controller so I could adjust the geometry dynamics to my taste.
Theory
I also mapped the feedback percentage to a dial on my controller so I could increase the trail of the spline to create an abstract form, or decrease the feedback to show the spline.
Procedural noise is used to inform colour variation, parameters of this noise are also controllable from my midi controller. To illustrate, as I increase the frequency of this noise, colour variation increases.
Alternative Iterations
In this clip I am experimenting with different colours, blur effects and spline harmonics.
Procedural noise also informs the shape of the 3D spline, hence when I decrease the frequency of this noise, the spline becomes smoother.
The system is very sensitive, meaning if I found a configuration I liked, because there are so many inter-related parameters, it was difficult to retrieve the previous configuration. I therefore spent a lot of time setting limits on my controller so the midi value would not exceed certain points.
