Chemotaxis
From Biocellion
This tutorial will guide you through the steps of adding a chemotactic force to the cells in your simulation. Requirements for chemotaxis include a population of agents, and a chemical field of a chemoattractant. The agents will move along the chemical gradient toward the chemoattractant.
In this example, a simple method is used to calculate the chemotactic force on a particle which responds to a chemoattractant , as follows:
- Generate a random unit vector , as a potential chemotactic force acting on .
- Along vector , sample ahead of , as well as behind , as and , respectively.
