XMQuaternionIdentity function (directxmath.h)
Returns the identity quaternion.
Syntax
XMVECTOR XM_CALLCONV XMQuaternionIdentity() noexcept;
Return value
An XMVECTOR union that is the identity quaternion.
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.
Given a quaternion (x, y, z, w), the XMQuaternionIdentity function will return the quaternion (0, 0, 0, 1).
