Estimates the coefficients of a plane so that coefficients of x, y, and z form a unit normal vector.
- P [in]
XMVECTOR describing the plane coefficients (A, B, C, D) for the plane equation
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
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.
