Computes the 2D cross product.
XMVECTOR XM_CALLCONV XMVector2Cross( FXMVECTOR V1, FXMVECTOR V2 );
Returns a vector. The 2D cross product is replicated into each component.
The following pseudocode demonstrates the operation of the function:
XMVECTOR Result; Result.x = V1.x * V2.y - v1.y * V2.x; Result.y = V1.x * V2.y - v1.y * V2.x; Result.z = V1.x * V2.y - v1.y * V2.x; Result.w = V1.x * V2.y - v1.y * V2.x; return Result;
Note that a 'cross-product' in 2D is not well-defined. This function computes a geometric cross-product often used in 2D graphics. XMVector2Orthogonal is another possible interpretation of a 'cross-product' in 2D.
