NVG 1.4 and 1.5 define several types of shapes. Most of them are quite common, such as polygons or ellipses, and some are
more specific, such as corridors.
NVG 2.0 defines additional properties, such as a time span, and additional shapes such as orbit and rectangle. In addition,
the area shapes in the NVG 2.0 model are special in that they can contain inner rings (holes).
TLcdNVG20Polygon class implements LuciadLightspeed’s
ILcdSurface interface, rather than
All other shapes directly implement the corresponding LuciadLightspeed interfaces, such as
ILcdEllipse, and so on.
You can semantically link all objects extending
TLcdNVG20SymbolizedContent to a symbol from a symbology, such as the military symbology MIL-STD 2525c. Create the link by setting their
NVG documents allow per-object styling. Domain objects extending
TLcdNVG20Content expose a
TLcdNVGStyle property detailing the styling information.
TLcdNVGStyle 's styling properties can be
null, which specifies that a default value should be used.
The Customizing the NVG visualization guide further explains this process.
