Virtual Tadpoles

Click inside the frame to add a virtual tadpole. There are two kinds of tadpoles:

  • Green tadpoles like to flock.
  • Red ones are singles and don't follow the crowd. However, flocking tadpoles are also attracted to them.

Use the menus above to chose the time-steps of the simulation and the character of the tadpole to be created.

Behavioral Animation

I designed this animation for Ken Perlin's Advanced Computer Graphics class. In our final project, I used similar algorithms to move and control a large number of autonomous actors in an three dimensional IMPROV-environment:

"The IMPROV Project at NYU's Media Research Lab is building technologies to produce distributed responsive virtual environments in which human-directed avatars and computer-controlled agents interact with each other in real-time, through a combination of Procedural Animation and Behavioral Scripting techniques."


Simulation and animation of crowd behavior is an active research area. Most of the work refers to Craig Reynolds Boids animation. His page also contains numerous links to similar research projects, mostly concerned with the simulation of flocks of animals (Terazopoulos' artificial life, Keio University's biological model simulation project).

A Swiss group at is working on the simulation of human crowds.

Some people are interested in human crowds for a different reasons than visual pleasure: The Defense Modeling and Simulation Office is looking at ...

"crowds massing for some protest... and the corresponding dispersal patterns of the crowd's response to the use of non-lethal weapons by responding troops."
