F_VN_OrthogonalVector_TcVnVector2_REAL

Computes an orthogonal vector to a given source vector.

Syntax

Definition:

FUNCTION F_VN_OrthogonalVector_TcVnVector2_REAL : HRESULT
VAR_IN_OUT
    aSrc        : TcVnVector2_REAL;
    aOrthogonal : TcVnVector2_REAL;
END_VAR
VAR_INPUT
    bNormalize  : BOOL;
    hrPrev      : HRESULT;
END_VAR

Inputs

Name	Type	Description
bNormalize	BOOL	If true, aOrthogonal length is normalized to 1, otherwise aOrthogonal has the same length as aSrc
hrPrev	HRESULT	HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)

In/Outputs

Name	Type	Description
aSrc	TcVnVector2_REAL	Source vector
aOrthogonal	TcVnVector2_REAL	Returns a vector orthogonal to aSrc

Return value

HRESULT
