Using fog in the 3D mode

For realistic simulations in 3D mode, you can add fog (List of 3D graphic parameters).

  • Linear mode from Fog start to Fog end. From the observer until Fog start, visibility is 100%. The fog looks dense if you choose a short distance between Fog start and Fog end. The fog looks less dense, the longer the distance is.
  • Exponential The fog begins at the location of the observer based on the Fog density defined in the 3D graphic parameter.

Notes:  

  • Vissim saves no settings with regard to fog. If Vissim is closed and then reopened; the fog is switched off.
  • The switching on of fog applies for all keyframes.
Examples of different types of fog effects

Fog mode: Off

Fog mode: Linear

Fog start 0.0 m: Fog starts at the location of the observer.

Fog-end 100.0 m: Visibility extends until the point of Fog end.

Fog mode: Linear

Fog start 40.0 m: Fog starts at a distance of 40 m from the observer.

Fog end 90.0 m: Visibility is limited from the point of fog start at 40.0 m and extends 50.0 m far until the point of fog end at 90.0 m.

Fog mode Exponential: Fog starts at the position of the viewer.

Fog density Default value 6.0: Fog density is relatively low, visibility is not limited.

Fog mode Exponential: Fog starts at the position of the viewer.

Fog Density: 30.0. This value is five times greater than the default value 6.0. This means visibility is very limited.
