[−][src]Function directx_math::XMVector3RefractV
pub fn XMVector3RefractV(
Incident: FXMVECTOR,
Normal: FXMVECTOR,
RefractionIndex: FXMVECTOR
) -> FXMVECTOR
Refracts an incident 3D vector across a 3D normal vector.
Parameters
Incident
3D incident vector to refract.
Normal
3D normal vector to refract the incident vector through.
RefractionIndex
3D vector whose x
, y
, and z-component
s 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
, undefined >.
Remarks
This function is identical to XMVector3Refract except that the RefractionIndex is supplied using a 3D vector instead of a float value.
