Function directx_math::XMVector2RefractV [−][src]
pub fn XMVector2RefractV(
Incident: FXMVECTOR,
Normal: FXMVECTOR,
RefractionIndex: FXMVECTOR
) -> XMVECTOR
Refracts an incident 2D vector across a 2D normal vector.
Parameters
Incident
2D incident vector to refract.
Normal
2D normal vector to refract the incident vector through.
RefractionIndex
2D vector whose x
and y
-components are both 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
, undefined, undefined >.
Remarks
This function is identical to XMVector2Refract except that the RefractionIndex is supplied using a 2D vector instead of a float value.
