fresnel

 

 

This node calculates Fresnel reflection and refraction vectors.

 

 

[Inputs]

 

Enabled - Enable or disable node evaluation.

 

#Vector - Vector that will be reflected and/or refracted.

 

#Normal - Normal around which the input vector will be reflected and/or refracted.

 

IOR - Index of refraction.

 

Normalize Vector - Computations require normalized vector, but in the case that input vector is already normalized you can uncheck this option.

 

 

[Outputs]

 

Reflect - Reflected vector (not normalized).

 

Refract - Refracted vector (not normalized).
