Function directx_math::XMVector2Orthogonal

pub fn XMVector2Orthogonal(V: FXMVECTOR) -> XMVECTOR

Computes a vector perpendicular to a 2D vector.

Parameters

V 2D vector.

Return value

Returns the 2D vector orthogonal to V.

Remarks

Note that a ‘cross-product’ in 2D is not well-defined. This function computes a generalized cross-product in 2D. XMVector2Cross is another possible interpretation of a ‘cross-product’ in 2D.

The following pseudocode demonstrates the operation of the function:

XMVECTOR Result;

Result.x = -V.y;
Result.y = V.x;
Result.z = 0;
Result.w = 0;

return Result;
