XMQuaternionSquad method

Interpolates between four unit quaternions, using spherical quadrangle interpolation.

Syntax


XMVECTOR XMQuaternionSquad(
  [in] XMVECTOR Q0,
  [in] XMVECTOR Q1,
  [in] XMVECTOR Q2,
  [in] XMVECTOR Q3,
  [in] float    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.

Return value

Returns the interpolated quaternion. If Q0, Q1, Q2, and Q3 are not all unit quaternions, the returned quaternion 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.

The use of this method requires some setup before its use. See XMQuaternionSquadSetup for details.

Platform Requirements
