Function directx_math::XMPlaneNormalizeEst [−][src]
pub fn XMPlaneNormalizeEst(P: FXMVECTOR) -> XMVECTOR
Estimates the coefficients of a plane so that coefficients of x, y, and z form a unit normal vector.
Parameters
P
XMVECTOR describing the plane coefficients (A
, B
, C
, D
) for the plane equation Ax+By+Cz+D=0
.
Return value
Returns an estimation of the normalized plane as a 4D vector whose components are the plane coefficients
(A
, B
, C
, D
) for the plane equation Ax+By+Cz+D=0
.
Remarks
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.
