XMVector4Orthogonal function (directxmath.h)
Computes a vector perpendicular to a 4D vector.
Syntax
XMVECTOR XM_CALLCONV XMVector4Orthogonal(
[in] FXMVECTOR V
) noexcept;
Parameters
[in] V
4D vector.
Return value
Returns the 4D vector orthogonal to V.
Remarks
A 4D cross-product is not well-defined. This function computes a generalized 'cross-product' for 4D vectors. XMVector4Cross is another geometric 'cross-product' for 4D vectors.
The following pseudocode demonstrates the operation of the function:
XMVECTOR Result;
Result.x = V.z;
Result.y = V.w;
Result.z = -V.x;
Result.w = -V.y;
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
