Function XMVector4Orthogonal

pub fn XMVector4Orthogonal(V: FXMVECTOR) -> XMVECTOR

Computes a vector perpendicular to a 4D vector.

Parameters

V 4D vector.

Return value

Returns the 4D vector orthogonal to V.

Remarks

A 4D cross-product is not well-defined. This function computes a generalized ‘cross-product’ for 4D vectors. XMVector4Cross is another geometric ‘cross-product’ for 4D vectors.

The following pseudocode demonstrates the operation of the function:

XMVECTOR Result;

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

return Result;
