● Base color: For color preview purposes, click the Color icon to open the
palette. Select the appropriate VISSIM color (for example, as set by a
type or class of vehicles or pedestrians) for the display of the 3D model.
This selection cannot be stored in this window. Color settings are
defined by means of color distributions per vehicle class or type, cf.
section 5.3 (for pedestrians, cf. section 7.1 respectively).
● # Polys: The variance of the number of polygons (high/low) is displayed.
Next to the button, the number of states being available for this model is
displayed.
● ANIMATE: In case of various model states (as required for walking
pedestrians, for example) all states are displayed automatically one by
one.
Alternatively, you may click the button indicating the particular direction
to call the display of either the previous or the next state manually.
Additionally to the global Level of Detail settings defined via VIEW – OPTIONS
– [3D], you may define different LOD display parameters for the same
distances and graphical display settings for additional distances for the
particular 3D model.
Click the or button to call the next LOD for this 3D model. The name of
the currently displayed level is displayed.
● Override global cutoffs: Check this option to redefine the global LOD
settings by 3D model:
- Simple (Simplified vehicle geometry beyond)
- No lighting (No lighting beyond)
- Blocks (Draw vehicle blocks beyond)
● Min dist/level: Enter the new distance
● # Polys (curr): Output of the number of polygons, the model consists of.
The closer the distance, the more polygons are usually required for
modeling.
For Static 3D models, also the Elevation value ±0 can be entered and the
degrees can be specified for rotation in any direction (YZ, XY, XZ).
In 2D mode the vehicle is always displayed with the values (vehicle length,
axle positions, …) entered / shown in the Geometry dialog. In 3D mode the
3D model from the selected file is used. The geometry values from the 3D
model file are ignored in the simulation after any modification in the
Geometry dialog. This can cause vehicles to overlap or keep too large
gaps in 3D mode. After loading an *.INP file a warning message is
displayed if the geometry data differs from the values in the 3D model file.
Accordingly, the selection of a new 3D model will overwrite all Geometry
data.
