Computes the 2D cross product.
Syntax
XMVECTOR XM_CALLCONV XMVector2Cross(
[in] FXMVECTOR V1,
[in] FXMVECTOR V2
) noexcept;
Parameters
[in] V1
2D vector.
[in] V2
2D vector.
Return value
Returns a vector. The 2D cross product is replicated into each component.
Remarks
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.
