Function XMVector4AngleBetweenVectors

pub fn XMVector4AngleBetweenVectors(V1: FXMVECTOR, V2: FXMVECTOR) -> XMVECTOR

Compute the radian angle between two 4D vectors.

Parameters

V1 4D vector.

V2 4D 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 4D vectors, it is faster to use XMVector4AngleBetweenNormals.
