WRLDBuildingContour Class Reference

Represents a building or part of building as a polygon with minimum and maximum altitudes. This can be used to construct an extruded polygon (prism) to visually represent the building. Complex buildings may be made up of multiple WRLDBuildingContour.

@property bottomAltitude

@property (nonatomic, readonly) CLLocationDistance bottomAltitude

The minimum altitude above sea level.

@property topAltitude

@property (nonatomic, readonly) CLLocationDistance topAltitude

The maximum altitude above sea level.

@property pointCount

@property (nonatomic, readonly) NSUInteger pointCount

The count of CLLocationCoordinate2D points in this contour.

– getPoints:

- (void)getPoints:(CLLocationCoordinate2D *)coordinates

Get points that are vertices of the building outline polygon, ordered clockwise from above.

Argument Description

The array of coordinates for points. It must be large enough to hold the coordinates.
