Function directx_math::XMVector4RefractV

pub fn XMVector4RefractV(
    Incident: FXMVECTOR, 
    Normal: FXMVECTOR, 
    RefractionIndex: FXMVECTOR
) -> XMVECTOR

Computes a vector perpendicular to a 4D vector.

Parameters

Incident 4D incident vector to refract.

Normal 4D normal vector to refract the incident vector through.

RefractionIndex 4D vector, all of whose components are equal to the index of refraction.

Return value

Returns the refracted incident vector. If the refraction index and the angle between the incident vector and the normal are such that the result is a total internal reflection, the function will return a vector of the form < 0.0, 0.0, 0.0, 0.0 >.

Remarks

This function is identical to XMVector4Refract except that the RefractionIndex is supplied using a 4D vector instead of a float value.
