STISIM Drive (SDL) - FOG - Fog Effects

This is a new event that allows you to dynamically display fog in the roadway scene. The fog event can be used to temporarily or permanently reduce the visibility in a scenario. Unlike in previous versions of the program where the fog was either on for an entire run or off for the entire run, the fog event allows the fog to be dynamic so that you can have it appear and disappear as a function of how far the driver has traveled. If you want to set fog for an entire run, this can be done using the atmospheric conditions found in the Other tab of the Configuration option found in the Options menu. The fog's color can be set using the "Set Simulation Colors" and "Assign Simulation Colors" options found in the Options menu.

EVENT PARAMETERS:

PARAMETER 1:	Longitudinal distance, in feet, that the beginning of the fog is away from the driver when it first becomes visible.
PARAMETER 2:	Depth to opacity. This is the distance, in feet, that the driver will be able to see into the fog.
PARAMETER 3:	The longitudinal length, in feet, of the fog event. The fog will disappear after driving this distance through it.
PARAMETER 4:	Transition distance, in feet, to go from no fog to full fog. This allows the fog to start and end gradually.

EXAMPLES:

5000,FOG,1000,1000,2000,500

The example FOG event above, shows how you would add a short patch of fog to a scenario. After the driver has driven 5000 feet, fog will start to appear 1000 feet in the distance. As the driver gets closer to the fog, it will start to get denser over a 500 foot distance, until the driver can only see 1000 feet ahead. After driving 1500 feet through the fog (2000 – 500), the fog will start to lessen, and over the final 500 feet it will disappear.
