Detailed Description

Class finding the nearest track point.

The constructor searches all active tracks for the point nearest to the given location. In case of more than four active tracks, the most nearest for loaders remain in the TS_nearest.Res array.

Since: 0.0

Definition at line 79 of file track_store.bi.

Constructor & Destructor Documentation

◆ TS_nearest()

TS_nearest::TS_nearest	(	BYVAL_AS_float	La,
		BYVAL_AS_float	Lo
	)

Find the point nearest to a location.

Parameters

La	Latiture [radians]
Lo	Longiture [radians]

This constructor searches in all enabled tracks the point nearest to the given location. In the result array TS_nearest.Res the four most nearest point/tracks get collected, if there're more than four tracks enabled.

Since: 0.0

Callback for search nearest point.

Parameters

Model	tree model
Path	line in Model
Iter	iter in Model
UserData	unused

Returns: FALSE (in order to continue)

This function is designed as a gtk_tree_model_foreach callback. It searchesn (2d) in all enabled tracks for the nearest point to a given location and stores the distance and the track in a free slot in the result array TS_nearest.Res. Whenn all slots are used, a slot with bigger distance gets replaced (if any).
