XMQuaternionSlerp method

Interpolates between two unit quaternions, using spherical linear interpolation.

Syntax


XMVECTOR XMQuaternionSlerp(
  [in]  XMVECTOR Q0,
  [in]  XMVECTOR Q1,
  [in]  float t
);

Parameters

Q0 [in]

Unit quaternion to interpolate from.

Q1 [in]

Unit quaternion to interpolate to.

t [in]

Interpolation control factor.

Return value

Returns the interpolated quaternion. If Q0 and Q1 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.

When t is 0.0f, the function returns Q0. When t is 1.0f, the function returns Q1.

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.
