Cross

template<typename T>
T Cross(

const XVector2<T> &a,

const XVector2<T> &b,

)

Computes the 2D cross product of two vectors.

For vectors (a.x, a.y) and (b.x, b.y), returns (a.x * b.y - a.y * b.x).

Template Parameters:

T – The component type of the vectors.

Parameters:

• a – [in] The first vector.

• b – [in] The second vector.

Returns:

The magnitude of the z-component if the vectors were in the xy plane.
