Visitations and Revisitations
August 14, 2018
Visitations and Revisitations is a series of four pieces by Matt Rogalsky, that was performed live at the Isabel Bader Centre for the Performing Arts. Visuals for each performance featured a number of new algorithms including a circular representation of audio waveforms as well as several flowers based on spiralling primitive shapes.
When designing a circular waveform, it was important to modify the radius of the circle such that the waveform reconnects at zero amplitude. Otherwise, a gap appears where the waveform reconnects. The radius of each circle was in this way dependant on the resonant frequency of the sound it was modelling.
