Detailed Description

The TSL3DSatelliteHelper is used to draw satellite paths in a 3D standard data layer.

◆ path() [1/2]

static TSL3DPolyline * TSL3DSatelliteHelper::path	(	TSLSatellite *	sat,
		const TSLTimeInstant &	currentTime,
		int	timeFrame,
		double	intTime,
		bool	afterNow = false,
		int	numPoints = 0,
		bool	actualTrack = true )

static

Calculate a satellite's ground or actual track given a start time and duration. The path drawn is historical by default, although can be set to be predictive. The resolution of the path is determined by either the interval value or the number of points.

If the interval time given is zero then the number of points is used. Number of points is zero by default.

If neither an interval time nor a number of points is specified, or if the line cannot be created a null pointer is returned.

Note that the interval time needs to be given in minutes.

Note also that the caller owns the resulting 3d polyline.

Parameters

sat	the satellite
currentTime	the end time (or start time) for the path
timeFrame	the time frame, in whole minutes
afterNow	by default, false, indicating that the path is historical, if set to true, the path is predictive
intTime	the interval time, in minutes - the satellite's position is calculated after every intTime minutes
numPoints	the number of points that the polyline should contain, defaults to 0
actualTrack	True if the actual 3D track should be returned, false if the ground track is required. Default true.

Returns: a 3D polyline representing the ground or actual track, false otherwise.
