XMVector4Orthogonal method

Computes a vector perpendicular to a 4D vector.

Syntax


XMVECTOR XMVector4Orthogonal(
  [in] XMVECTOR V
);

Parameters

V [in]: 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.
