XMQuaternionSquadV method

Interpolates between four unit quaternions, using spherical quadrangle interpolation.

Syntax


XMVECTOR XMQuaternionSquadV(
  [in]  XMVECTOR Q0,
  [in]  XMVECTOR Q1,
  [in]  XMVECTOR Q2,
  [in]  XMVECTOR Q3,
  [in]  XMVECTOR T
);

Parameters

Q0 [in]

First unit quaternion.

Q1 [in]

Second unit quaternion.

Q2 [in]

Third unit quaternion.

Q3 [in]

Fourth unit quaternion.

T [in]

Interpolation control factor. All components of this vector must be the same.

Return value

Returns the interpolated quaternion. If Q0, Q1, Q2, and Q3 are not unit quaternions, the resulting interpolation is undefined.

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.

This function is identical to XMQuaternionSquad except that T is supplied using a 4D vector instead of a float value.

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.
