Changing the 3D viewing angle (focal length)

You can select the viewing angle in 3D mode. This corresponds to the setting of the focal length in photography.

The default value of the viewing angle is 45° in Vissim. This corresponds to a focal length of 43mm in a 35mm system.

  • ►  If you want to reduce the viewing angle by two degrees, press the Ctrl+Page up keys.
  • ►  If you want to enlarge the viewing angle by two degrees, press the Ctrl+Page down keys.

The current viewing angle is displayed in the first column of the status bar during the change.

Notes:  

  • Vissim does not save any changes to the viewing angle. The default viewing angle is set again the next time you open Vissim.
  • The modification of the viewing angle applies to Rotate mode (3D) and Flight mode (3D) and all keyframes.

The table displays the corresponding focal lengths for different viewing angles:
