Description

• I designed a boids simulation that represents a school of fish in the ocean. Each fish was designed as a green triangle over a yellow triangle with an ellipse for the eye. The simulation will start with 25 fish and will generate 3 more fish per frame until it reaches 50.
• The user can turn on an off:
  • alignment (steer towards the average heading of local flockmates)
  • cohesion (steer to move towards the average position (center of mass) of local flockmates)
  • separation (steer to avoid crowding local flockmates)

User interaction

• mouse left click: add more fish (up to 100)
• S: separation feature on
• s: separation feature off
• C: cohesion feature on
• c: cohesion feature off
• A: alignment feature on
• a: alignment feature off
• F: 10 of the fish will follow the mouse and will disappear when then reach it (follow feature)
• f: follow feature off
• d: double the speed of the fish up to a maximum speed
• h: reduce the speed of the fish by 2

Programming language

• Processing

Libraries

• peasy: PeasyCam provides a dead-simple mouse-driven camera for Processing.
