Function directx_math::quaternion::XMQuaternionReciprocalLength [−][src]
pub fn XMQuaternionReciprocalLength(Q: FXMVECTOR) -> FXMVECTOR
Computes the reciprocal of the magnitude of a quaternion.
Parameters
Q
Quaternion to measure.
Return value
Returns the reciprocal of the magnitude of Q
.
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.
