Detailed Description

Function for boolean calculations on wings/fuselages.

These function currently only implement intersection algorithms between two shapes defined in cpacs ot a shape and a plane. Shapes or geometries are identified with their cpacs uid.

Currently only wings, wing segments, fuselages, and fuselage segments can be used in the intersection routines.

		int	curve1Idx,
		const char *	curvesID2,
		int	curve2Idx,
		double	tolerance,
		char **	intersectionID
	)

tiglGetCurveIntersection computes intersection point of two (intersection) curves. Both curves are the result of a previous intersection (e.g. Fuselage-Wing Intersection).

The curves must be specified by their intersectionIDs and an index of the wire in the intersection. For each calculated intersection, the distance between the point on the first curve to the point on the second curve is smaller than the tolerance specified by the user.

It returns an intersection ID for further computations on the result. To query the number of intersection points, call tiglGetCurveIntersectionCount. To query intersection points, tiglGetCurveIntersectionPoint or tiglGetCurveParameter has to be called.
