Visualizing Perlin Noise

Processing, Kinect

For this project I have explored Perlin noise and interactivity. The end result is an installation, which uses a Kinect and a projector for sensing people in spaces and for projecting the visuals.

My visuals are based on creating particles and moving them with a certain velocity that is based on the perlin noise. The particles leave a trail behind forming aesthetically pleasing lines, which are pseudo random in nature. The DLA walkers on the other hand quickly fade away creating grid line patterns.

Some of the features of the current project:

  • Mouse Interaction: To quickly test the visuals, I am using the mouse clicks for launching the particles / walkers.
  • Kinect Interactions: When a person is detected in space, I begin to track his hands.
  • As soon as the distance between the hand and the corresponding hip is more than 35 cms, the hand becomes active and the particles / walkers come alive to the corresponding position the projected display.
  • Gestures: The particles/ walkers are added to the system when the viewers, wave their hands or push.
  • Perlin Noise: the number of people present in the space varies the noise detail. When no one is present only 2 octaves are in use. For every additional person detected number of octaves gets incremented. At this point, I am not using any fall off so all the octaves are equally weighted.
  • Random Walkers:  I additionally implemented random walkers for where a bunch of walkers are launched into space and perform a grid like random walk and slowly fades away.

Color Palettes:

  • Demo Mode: Using 5 colors, which are chosen randomly.
  • Installations Mode:  Every person is allotted a distinct color.
  • Art mode: Using 2 complementary colors that switch randomly.
