Claim 0:
1. A computer-implemented method for determining an attenuation of a wind caused by a simulated obstacle and experienced by a simulated vehicle in a simulation running on a simulation device, comprising:
receiving a wind direction and an initial speed for a simulated wind;
generating a line of sight vector based on the wind direction, the line of sight vector associated with the simulated vehicle and having a source position, a given direction and a given length, the given direction being one of opposite to the wind direction and identical to the wind direction, the source position being on the simulated vehicle, and a maximum distance for an obstacle to create wind attenuation for the simulated vehicle defining the given length of the line of sight vector;
determining that a simulated obstacle is present within a distance corresponding to the length of the line of sight vector;
calculating a wind attenuation gain using a distance between the simulated obstacle and the simulated vehicle;
calculating an actual speed for the simulated wind using the initial speed of the simulated wind and the wind attenuation gain; and
transmitting the actual speed of the simulated wind to a simulation engine associated with the simulation device, the simulation engine using the actual speed of the simulated wind to control the simulated vehicle.
