Function XMQuaternionLengthSq

pub fn XMQuaternionLengthSq(Q: FXMVECTOR) -> FXMVECTOR

Computes the square of the magnitude of a quaternion.

Parameters

Q Quaternion to measure.

Return value

Returns a vector. The square of the magnitude of Q 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.
