[−][src]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;
