# XMVector2Cross function

Computes the 2D cross product.

## Syntax

```
XMVECTOR XM_CALLCONV XMVector2Cross(
FXMVECTOR V1,
FXMVECTOR V2
);
```

## Parameters

`V1`

2D vector.

`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.
