WSF_EXPORT double	Intercept (const double aBodyLoc[3], double aBodySpd, const double aTgtLoc[3], const double aTgtVel[3], double aIntLoc[3], double aPredictAheadTime=0.0)

Detailed Description

Method(s) for performing intercept calculations.

Function Documentation

Intercept()

double WsfIntercept::Intercept	(	const double	aBodyLoc[3],
		double	aBodySpd,
		const double	aTgtLoc[3],
		const double	aTgtVel[3],
		double	aIntLoc[3],
		double	aPredictAheadTime = 0.0 )

A low level routine to calculate the intercept point and the time to intercept. This routine ignores the heading of the intercepting body and assumes it can turn instantly.

Parameters

aBodyLoc	The location of the body doing the intercepting.
aBodySpd	The speed of the body doing the intercepting. (assumed constant)
aTgtLoc	The 'target' location.
aTgtVel	The 'target' velocity vector.
aIntLoc	[output] The intercept location.
aPredictAheadTime	The predict ahead time to add/remove additional time to intercept.

Returns

The time to the intercept point. If the value is less than zero then intercept is not possible and aIntLoc will be set to the value of aTgtLoc.

Note

The input vectors must all have the same reference frame, i.e. they must all be WCS or must all refer to the same NED frame.
