Claim 9:
10. A system 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:
a vector module configured for receiving a direction of a simulated wind and generating a line of sight vector based on the wind direction, the line of sight vector having a source position, a given direction and a given length, the given direction being one of opposite to a 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;
a distance module configured for determining that a simulated obstacle is present within a distance corresponding to the length of the line of sight vector;
a gain module configured for receiving a distance between the simulated obstacle and the simulated vehicle using the line of sight vector and calculating a wind attenuation gain using the distance between the simulated obstacle and the simulated vehicle, the distance being at most equal to the given length of the line of sight vector; and
a speed module configured for receiving an initial speed for a simulated wind, 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.
