Function XMVector3AngleBetweenVectors

pub fn XMVector3AngleBetweenVectors(V1: FXMVECTOR, V2: FXMVECTOR) -> FXMVECTOR

Computes the radian angle between two 3D vectors.

Parameters

V1 3D vector.

V2 3D vector.

Return value

Returns a vector. The radian angle between V1 and V2 is replicated to each of the components.

Remarks

If V1 and V2 are normalized 3D vectors, it is faster to use XMVector3AngleBetweenNormals.
