Street Parameters

Street Parameters can be individually set for each graph segment.

The parameters for Street Shape creation can be specified through the street parameter panel in the inspector


Parameter panel for street shape creation

Attributes can be mapped to Default, User, Object or to a map layer. See Mapping Attributes for details.

The following parameters are available for the user to control the resulting street shapes:

General Parameters

Parameter Function
shapeCreation If true, shapes are created from the street segment.

Street Width and Offset Parameters

Parameter Function
streetWidth Defines the width of the main street shape.
streetOffset Defines the distance the geometry will be offset from the center line.
sidewalkWidthLeft Defines the width of the left sidewalk.
sidewalkWidthRight Defines the width of the right sidewalk.
sidewalkWidthRight Defines the width of the right sidewalk.

Precision Parameter

Parameter Function
precision Graph nodes are interpolated using Bezier splines, resulting in curved streets. This parameter defines the spline sampling precision, i.e. 0 leads to a minimal and 1 to a maximal number of spline sampling points.

Lane Width Parameter

Parameter Function
laneWidth Determines the width of lanes used for UV texture mapping of streets.

Street widths are given in absolute length units, precision is given in a normalized [0, 1] range.

Auto-generated connection attributes

Connection attributes provide basic information about the underlying graph and give context information. CGA rules may want to access the following attributes.


Left: A street shape selected in the viewport. Right: The generated connection object attributes in the inspector.

Parameter Value
connectionStart Hints as to the adjacent geometry at the start or end of a street segment shape. Values include: STREET, CROSSING, JUNCTION, JUNCTION_ENTRY, DEAD_END, FREEWAY, FREEWAY_ENTRY and ROUNDABOUT
connectionEnd
sidewalkSide Which side of the street this Sidewalk shape is on, relative to the street direction: either Left or Right. SidewalkSide is only added to sidewalk shapes.

Connection attributes are object attributes of the graph segment and are inherited to the shape. Note the italic font in the shape's inspector.
