XMVector3AngleBetweenNormals

Computes the radian angle between two normalized 3D vectors.

Syntax

XMVECTOR XMVector3AngleBetweenNormals(
         XMVECTOR N1,
         XMVECTOR N2
)  

Parameters

N1
Type: XMVECTOR 

Normalized 3D vector.

N2
Type: XMVECTOR 

Normalized 3D vector.

Return value

Type: XMVECTOR 

Returns a vector. The radian angle between N1 and N2 is replicated to each of the components.
