XMQuaternionLengthSq function (directxmath.h)
Computes the square of the magnitude of a quaternion.
Syntax
XMVECTOR XM_CALLCONV XMQuaternionLengthSq(
[in] FXMVECTOR Q
) noexcept;
Parameters
[in] Q
Quaternion to measure.
Return value
Returns a vector. The square of the magnitude 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.
