Verlet Physics and Springs

I created some threads made of particles connected through springs. Then I set a distance by which the particles are attracted to each other. If two particles are within that distance a new spring connection si created between the two.

Delaunay Portraits

In this software some particles are created randomly above an image. The probability of each particle’s creation is a function of the color value of the pixel in that location. Then the particles are used as vertices of a Delaunay tessellation. I made a GUI to control various parameters such as the number of particles, the distribution curve of the probability, the color, etc.

The Three Graces

Magnetic particles interacting with each other. Every 100 frame two new particles are born. The size of the particles is mapped on the image of the three graces by Antonio Canova. A grid structure is used to optimize the number of calculations. The code of this sketch uses polygons to render particles to take full advantage of the GPU.

Dance Between the lines

This work, done during a residency at Scene44, was the natural continuation of one of Recipient Collective past projects: Yi Ou Lai. From the visual point of view we wanted to further develop the idea of threads as a representation of the links between Chinese and European culture. We also decided to experiment with the visuals by introducing interactive elements that would translate the movement of the dancers into animation.  Music and sound are integral parts of the creative process, in this particular case, the music was composed by Alessandro Inguglia specifically for the show during the stay in Marseille.

Stigmergy Agents

From Wikipedia: Stigmergy is a mechanism of indirect coordination, through the environment, between agents or actions. The principle is that the trace left in the environment by an action stimulates the performance of a next action, by the same or a different agent. In that way, subsequent actions tend to reinforce and build on each other, leading to the spontaneous emergence of coherent, apparently systematic activity. Stigmergy is a form of self-organization. It produces complex, seemingly intelligent structures, without need for any planning, control, or even direct communication between the agents. As such it supports efficient collaboration between extremely simple agents, who lack any memory, intelligence or even individual awareness of each other. In this simulation, the agents move on a vector field where general direction is always rotating. Their movement is also influenced by some chemical attractors that each agent deposits on the ground, modifying the structure of the field.
