Detailed Description

Functions that finds the localization of objects.

Function Documentation

Check if coordinate c is on line boundary or on line interior (see explanation above for definition of boundary and interior of a line).

Parameters:

c	The coordinate to be tested.
l	The line used in the test.

Obs: Do box elimination.

Check if coordinate c is on segment (segment is closed).

Parameters:

c	The coordinate to be tested.
c1	The first segment's coordinate.
c2	The second segment's coordinate.

TL_DLL bool TeLocateLineSegment	(	TeCoord2D &	pin,
		TeLine2D &	line,
		int &	segment,
		double	tol = `0.0`
	)

Locate the nearest line segment of a coordinate.

Parameters:

pin	The coordinate.
line	The line.
segment	The position of the segment in the line
tol	Tolerance.

Point in polygon inside/outside/boundary code.

Parameters:

c	The coordinate to test.
r	The simple polygon to test.

Note:: Check if point is INSIDE of a given ring. The ring is treated as a simple polygon (no holes).

Thesis, Department of Electrical Engineering and Computer Science, Massachusetts Institute of Technology, 1993. Obs: Doesn't do box elimination.
