Function XMVector2AngleBetweenVectors

pub fn XMVector2AngleBetweenVectors(V1: FXMVECTOR, V2: FXMVECTOR) -> XMVECTOR

Computes the radian angle between two 2D vectors.

Parameters

V1 2D vector.

V2 2D 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 2D vectors, it is faster to use XMVector2AngleBetweenNormals.
