Computes the direction vector between 2 points.

Syntax

Definition:

HRESULT PointToPointDirection(
    HRESULT            hrPrev,
    TcVnPoint2_DINT&   aPoint1,
    TcVnPoint2_DINT&   aPoint2,
    TcVnVector2_LREAL& aDirection,
    bool               bNormalize
)

Parameters

Name	Type	Description
hrPrev	HRESULT	HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)
aPoint1	TcVnPoint2_DINT&	Point 1
aPoint2	TcVnPoint2_DINT&	Point 2
aDirection	TcVnVector2_LREAL&	Returns the direction vector from aPoint1 to aPoint2
bNormalize	bool	If true, aDirection length is normalized to 1, otherwise aDirection length is the distance between aPoint1 and aPoint2
