4.3.1.3 Changing the Field of View (Focal Length)
The 3D Graphics Mode
You can adjust the viewing angle that is used to look at a 3D scene. This is
similar to changing the focal length of a camera. The standard viewing angle
in VISSIM is set to 45°, which is a focal length equivalent of about 43mm (for
a 35mm camera system).
To change the field of view, use one of the options below:
► Press CTRL+PGUP or G to decrease the viewing angle by 1 degree
(i.e. moving a zoom lens towards the telephoto end).
► Press CTRL+PGDN or T to increase the viewing angle by 1 degree
(i.e. moving a zoom lens towards the wide-angle end).
The current viewing angle is displayed in the second section of the status bar
while the viewing angle is changed.
VISSIM does not store any changes to the viewing angle. As soon as
VISSIM is closed and reopened, the standard value applies.
Changing the viewing angle applies to all 3D navigation modes as well as
all the keyframes.
The following table shows the focal length equivalents of various viewing
angles:
View. angle F. length (35mm) View. angle F. length (35mm)
4° 500mm 38° 53mm
7° 300mm 40° 50mm
10° 200mm 44° 45mm
11° 180mm 54° 35mm
15° 135mm 65° 28mm
20° 100mm 72° 25mm
24° 85mm 81° 21mm
29° 70mm 90° 18mm
4.3.2 3D Visualization of Vehicles and Pedestrians
3D models in VISSIM can be assigned to each type of vehicles or
pedestrians respectively using model and color distributions (cf. sections
5.2.4 and 5.2.5 for details).
