Modeling the Spread of a Virus in a Modern Environment Tyler Haines Computer Systems Lab 2009-2010 1

Introduction A real-time simulation of the spreading of a virus in a building Simulates the path of a virus spreading from host to host Can see what style of buildings reduce the chance of a virus spreading 2

Background Main system, graphics, interface are all written in Java Information on virus spreading Airborne 3

Background Potential field AI concept for basic directional steering 4 http://aigamedev.com/open/tutorials/potential-fields/ 4

Background Main pathing uses “probe points” 5

Results Virus Smaller hallways cause an increase in people density, and increase the chance of getting infected Pathing You cannot rely on only one type of pathing algorithm alone Potential field + “probe points” 10
