LineIntersectionPointAndAngle

Computes the intersection point and angle between two lines (returns S_FALSE if the provided lines are parallel).

Syntax

Definition:

HRESULT LineIntersectionPointAndAngle(
    HRESULT            hrPrev,
    TcVnVector4_LREAL& aLine1,
    TcVnVector4_LREAL& aLine2,
    TcVnPoint2_REAL&   aIntersecPoint,
    float&             fAngle,
    bool               bAngleInDegrees
)

Parameters

Name	Type	Description
hrPrev	HRESULT	HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)
aLine1	TcVnVector4_LREAL&	First line. The first and second element describe the x and y component of a vector collinear to the line. The third and fourth element describe the x and y component of a point on the line.
aLine2	TcVnVector4_LREAL&	Second line. The first and second element describe the x and y component of a vector collinear to the line. The third and fourth element describe the x and y component of a point on the line.
aIntersecPoint	TcVnPoint2_REAL&	Returns the intersection point of aLine1 and aLine2.
fAngle	float&	Returns the intersection angle of aLine1 and aLine2.
bAngleInDegrees	bool	If TRUE, fAngle is in degrees. If FALSE, fAngle is in radians.
