Typedef Documentation

typedef struct AELineSegment2 AELineSegment2

Function Documentation

s32 AEBuildLineSegment2	(	AELineSegment2 *	pLS,
		AEVec2 *	pPt0,
		AEVec2 *	pPt1
	)

Initalize pLS using pPt0 and pPt1. Also computes the normal (unit vector) and the dot product of the normal with one of the points.

Warning

The distance between pPt0 and pPt1 should be greater than EPSILON.

Parameters

[out]	pLS	Pointer to AELineSegment2 to be set.
[in]	pPt0	Pointer to AEVec2 for input.
[in]	pPt1	Pointer to AEVec2 for input.

Return values

s32	Returns 1 if pLS is successfully intialized. Else returns 0.
