Created by James Alliban, Nova is an experimental study of the slit-scan technique with a particular focus on emphasising its spacial and temporal properties. The slit-scan image is created using video footage of bioluminescent deep sea creatures, particularly Comb Jellyfish. The resulting structure resembles a surreal organism that is locked into an ever-increasing state of perpetual growth, decay and transformation.
The structure is built and rendered in realtime using openFrameworks. It uses the incoming column of pixels from the video to determine the z-depth of the vertices emanating from the centre (depth based on pixel brightness). The new vertices continually radiate outwards undergoing a range of forces. These include perlin noise (standard) and verlet integration for cloth simulation (following this excellent explanation). As the vertices reach the edge of the 'organism' they increase in agency while their connections begin to weaken. This results in more tearing and disintegration.
