XMVector2AngleBetweenVectors method

Computes the radian angle between two 2D vectors.

Syntax


XMVECTOR XMVector2AngleBetweenVectors(
  [in]  XMVECTOR V1,
  [in]  XMVECTOR V2
);

Parameters

V1 [in]

2D vector.

V2 [in]

2D 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 2D vectors, it is faster to use XMVector2AngleBetweenNormals.

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

Namespace

Use DirectX.
