XMQuaternionDot method

Computes the dot product of two quaternions.

Syntax


XMVECTOR XMQuaternionDot(
  [in] XMVECTOR Q1,
  [in] XMVECTOR Q2
);

Parameters

Q1 [in]

First quaternion.

Q2 [in]

Second quaternion.

Return value

Returns a vector. The dot product between Q1 and Q2 is replicated into each component.

Remarks

The DirectXMath quaternion functions use an XMVECTOR 4-vector to represent quaternions, where the X, Y, and Z components are the vector part and the W component is the scalar part.

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.
