Negative Feedback Enables Fast and Flexible Collective Decision-Making in Ants. Positive feedback plays a major role in the emergence of many collective animal behaviours.
In many ants pheromone trails recruit and direct nestmate foragers to food sources. The strong positive feedback caused by trail pheromones allows fast collective responses but can compromise flexibility. Previous laboratory experiments have shown that when the environment changes, colonies are often unable to reallocate their foragers to a more rewarding food source. Physijs - a physics plugin for threejs.
Examples Physics plugin for three.js Physijs brings a very easy to use interface to the three.js framework.
One of the reasons three.js is so popular is because it is so incredibly easy for graphics newbies to get into 3D programming. Physijs takes that philosophy to heart and makes physics simulations just as easy to run. Tech. HyperPhysics.
