Function directx_math::XMVector2Cross

pub fn XMVector2Cross(V1: FXMVECTOR, V2: FXMVECTOR) -> XMVECTOR

Computes the 2D cross product.

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.
