Article
02/22/2024

Compute the radian angle between two 4D vectors.

Syntax

XMVECTOR XM_CALLCONV XMVector4AngleBetweenVectors(
  [in] FXMVECTOR V1,
  [in] FXMVECTOR V2
) noexcept;

Parameters

[in] V1

4D vector.

[in] V2

4D vector.

Return value

Returns a vector. The radian angle between V1 and V2 is replicated to each of the components.

Remarks

If V1 and V2 are normalized 4D vectors, it is faster to use XMVector4AngleBetweenNormals.

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.
