Function directx_math::XMVector3NormalizeEst [−][src]
pub fn XMVector3NormalizeEst(V: FXMVECTOR) -> FXMVECTOR
Estimates the normalized version of a 3D vector.
Parameters
V 3D vector.
Return value
Returns an estimate of the normalized version of V.
Remarks
For a vector with 0 length or infinite length, this function returns a vector of QNaN.
Est functions offer increased performance at the expense of reduced accuracy. Est functions are appropriate
for non-critical calculations where accuracy can be sacrificed for speed. The exact amount of lost accuracy
and speed increase are platform dependent.
