Refracts an incident 2D vector across a 2D normal vector.
XMVECTOR XMVector2RefractV( [in] XMVECTOR Incident, [in] XMVECTOR Normal, [in] XMVECTOR RefractionIndex );
- Incident [in]
2D incident vector to refract.
- Normal [in]
2D normal vector to refract the incident vector through.
- RefractionIndex [in]
2D vector whose x and y-components are both equal to the index of refraction.
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 < 0.0f, 0.0f, undefined, undefined >.
This function is identical to XMVector2Refract except that the RefractionIndex is supplied using a 2D vector instead of a float value.
