VISSIM 5.30-05 User Manual

4.3 The 3D Graphics Mode
The 3D Graphics Mode
In the VIEW menu, click the 3D Mode command (default shortcut CTRL+D) to
call the three-dimensional display of the VISSIM model. Furthermore, also
static elements can be added to the network display at any network position.
The network display can be viewed from any observer position.
Except for placing static 3D models, the 3D graphics mode is intended
solely for presentation purposes. All network editing is to be done in 2D
graphics mode.
If a background image is active, when changing into 3D mode for the first
time (with that bitmap visible) it may take a moment for VISSIM to convert
the image to a 3D texture.
Display option settings can be stored in the *.INI file, cf. section 4.5.
Static 3D objects are taken into consideration when the rectangular floor
space is calculated. In this way, resulting gaps between the models and the
floor area can be avoided and also view problems in case of very large
models.
4.3.1 Navigation
This section describes the options how to move the observer position in 3D
mode.
4.3.1.1 Navigation Modes
In 3D mode additional toolbar buttons become active. The following
commands are available in the Navigation toolbar:
Show Entire Network: Displays the entire network.
Dynamic Zoom: In contrast to the ZOOM command in 2D which uses a
window to select the new viewing area DYNAMIC ZOOM in 3D moves the
network closer dynamically by dragging the mouse from left to right and
moves the network further away by dragging the mouse from right to left.
A right click restores the previous view. Alternatively the mouse wheel can be
used to zoom in/out independently of the current navigation mode.
Zoom by Factor: Zooms by a user-defined factor: Values < 1.0 zoom in.
