XMVector2Orthogonal function (directxmath.h)
Computes a vector perpendicular to a 2D vector.
Syntax
XMVECTOR XM_CALLCONV XMVector2Orthogonal(
[in] FXMVECTOR V
) noexcept;
Parameters
[in] V
2D vector.
Return value
Returns the 2D vector orthogonal to V.
Remarks
Note that a 'cross-product' in 2D is not well-defined. This function computes a generalized cross-product in 2D. XMVector2Cross is another possible interpretation of a 'cross-product' in 2D.
The following pseudocode demonstrates the operation of the function:
XMVECTOR Result;
Result.x = -V.y;
Result.y = V.x;
Result.z = 0;
Result.w = 0;
return Result;
Platform Requirements
Microsoft Visual Studio 2010 or Microsoft Visual Studio 2012 with the Windows SDK for Windows 8. Supported for Win32 desktop apps, Windows Store apps, and Windows Phone 8 apps.Requirements
